Powerful, Efficient and Reliable BLDC Motors We are leading manufacturer of general-purpose brushless dc (BLDC) motors with power range from 200W to 20KW, and the voltage range from 24V to 120V DC. Cromotor V3 The QS motor company has also decided to begin selling their E-motorcycle hubs with axles that that have been modified to fit a bicycle. Range: 50 miles. In this example, a motor spinning 480-RPMs, would be traveling 37-MPH (59-km/h) in a common 26-inch outer-diameter (OD) of tire, but…if you switched to a smaller 17-inch moped rim with the recommendad 2.5-inch tire, the OD would be roughly 21-inches, and then the 480-RPM would result in 31-MPH (49-km/h). High-performance reliable 48V 1000W MXUS electric motor rear hub motor. The old common style is a thin stamped-steel plate. It only has a single-speed freewheel (of course! The quality of the steel in the laminations (and also their thickness) can affect how much eddy current heat a motor will suffer. If you want to ventilate a hubmotor, I advise you to spray a coating onto the stator to water-proof it against rust (see our article on hot rodding hub motors for more details). The … Motor Type: BLDC Hub Motor with Permanent Magnets, 2. From the outside, a geared hub motor is usually smaller in radius but wider than a direct drive hub. 5★ We’ll tell you who has what. 5% coupon applied at checkout Save 5% with coupon. Once the motor cools down, the CA-V3 will re-apply the amps from the controller. Moped rims that are 1.8-inch wide are available if you want a 3.5-inch tire. The extra copper mass in this motor makes this hubmotor the heaviest of these options, and the biggest problem with it will be finding the space on your frame to mount a big enough battery to keep it fed. This provides the builder with a LOT of options when trying to balance which voltage, tire-diameter, and top-speed you want. Their motor phase wires are thicker than the other motors listed, and their axle design is stronger. Notice the bump in shape to accomodate the extra axle-shoulder width. Don’t let the 1500W catalog name fool you. However…they also have a smaller amount of copper mass than a DD hub, and they have a poor heat-shedding path. ★★★★★ You would drill a small hole near the axle, and with that hole positioned below the axle, you would add oil up to that point (you don’t fill up the motor completely). Here is part of an advertisement for QS Motor. The popular 5T at 72V would provide 518 unloaded RPMs, and when mounted in a 26-inch tire, that would be 40-MPH (64 km/h), and…72V X 70A = 5,000W. ATF will not boil at the temperatures that are below the max temps we recommend for these motors, plus ATF is affordable, readily available, and already has anti-foaming agents. This makes it light, and still able to properly seat a 2.0-3.0 inch wide tire. Dump truck driver in the 2000's/SW Utah. Details for 5kw electric bike hub motor QS V3 5000w motor 10kw peak power.

I can’t imagine going to the effort of buying a motor as heavy and capable as these, and then running it off of only 48V, so…these motors are most frequently seen using something between 72V-100V. Weight: 81.5 lbs. If you like using tons of amps, you might be well-served by a sensorless controller (or at least have one handy as a spare). The stepper motors should be connected via a driver IC (like A4988) with a 1, 2 or 3-wire connection: Although a rear suspension takes up some of the precious frame area with the shock absorber (limiting the size of a central frame-mounted battery), recent improvements in the battery cells that are available mean that even a small battery pack can have decent power and range. Product Description. Since the copper wire is already getting more heat than we want, the undesirable heat from eddy currents can be reduced by making the electromagnet cores out of a stack of thin steel plates, called laminations. Due to the angled holes in the moped rims, a large DD hub can be laced with a one-cross pattern, which is much better than a radial pattern (which many builders had been previously forced to use to get a large hub in a smaller rim). ), and if the heat keeps rising, you can program the amps to be completely cut off at your designated set-point (like 200fF/ 93C?). For the street, a smaller diameter wheel is more efficient (due to the higher motor “magnet speed” per distance that the wheel traveled), but…switching from one wheel to a smaller one will also lower your top speed. I’ve listed my recommended power levels for each motor option, but…the real limit to how much power you can feed them is…how much heat they can survive? However, this year there has been a dramatic improvement in the selection of high-amp 18650 cells, which have proven to be the safest batteries available. Here is the article on the Edge motor I tested, I like it. MXUS 3000W V2 1. Using 50V X 50A = 2,500W is now a plug-and-play option that you can use with confidence. I have also heard of electrical transformer oil being used successfully. Even if you don’t add a read-out to it right away, you have it available without needing to take the motor apart to add one later. Pic courtesy of ES member ridethelightning. 6T______7.3 This motor made a big splash on the E-bike scene last year. ), and will also spend a lot of time at speeds above 30-MPH…a large rear DD hub can be the ticket to a very fun ride. Useful Info: Torque ...

There is a thin layer of air between the hot (stationary) stator and the spinning aluminum side-plates. This is the hubmotor that got bystanders to start yelling “That’s not an E-bike, it’s a motorcycle!”. If the 35mm wide stator had been made wider, you’d have fewer gears, and also…the motor would be heavier and more expensive. Trust us on this! ), which would raise the top-speed back to normal when compared to using that particular Kv of hub at 48V. 2★ The 205 in the name means the stator is 205mm in diameter, and the 35H means the stator is 35mm wide (“H” is for height, the Chinese motor catalogs list their internal construction this way, viewing the motor on its side). Crystalyte recently changed the motor-case so that it uses common-style spokes, instead of the “straight-pull” spokes shown here. Watch the 2-minute video of Luke/liveforphysics and his friends when they melt down a common Crystalyte H35 hubmotor to see how much side-plate ventilation helps it. output power range from 300W to 2000W, its torque range on continuous duty is 1.2-3.5Nm, on intermittent duty up to 3-8.75Nm. The front motor is for 100mm standard dropouts. wide bottom bracket shell and 35mm inside diameter.

As with most electric motors, the required load and speed dictate the size of an in-hub motor necessary to handle a given application. There have been many experiments that either added a little Automatic Transmission Fluid (ATF) to the motor, or… simply drilling some holes in the sideplate to let the excess heat out. The thick aluminum spokes on the right absorb heat-spikes when accelerating, and are well worth the extra price for the higher performance and helping the motor survive heavy abuse. 2. You can have many wraps of thinner wire, or fewer wraps of thicker wire. They also provide good torque by spinning a smaller (and lighter) motor much faster and then reducing the RPMs down to the wheel speeds with an internal set of gears. So, I purchased 36V 48V 250W electric bike hub motors High Speed Brushless Gear Hub Motor e-bike Motor Front Wheel Drive DQ100. If bruchless motors like to spin at high RPMs I don't understand why an appropriately powered direct drive hub motor would not provide a high top speed as the faster it spins the efficient it should become. Once you trace the shape of metal plate you’d need for whatever frame you have, the custom torque-plates can be water-jetted or laser-cut, and then shipped directly to your mailbox. Last year, we wrote an article on several new selections of safe high-amp cells. Even if you don’t need 39-MPH, you might order the “fast” 4T if you want to lace the hub to a smaller 17-inch moped rim (similar to a 20-inch bicycle rim). The “H” hubmotor family doesn’t have the option of an aluminum stator-core, or thinner laminations. Temp Sensors GOGOA1.com, plot no 36, sector 2A, Near NMMC school, koparkhairane, Navi Mumbai. How to make high speed brushless moto , Supper fast brushless motorRelated Videos1. I recommend buying the bare unlaced motor, and using a moped rim. However, as some of the electrons in the steel material move around due to the magnetic forces, their movement causes “eddy current” heat. They can freewheel very easily when not using any power. • Motor weight less than 30 kg • Must interface with EV-C200 controller • Acceleration from 0-60 mph in less than 15 s. • Solar/Battery power must be used • Constant Torque with speed variation. The aluminum stator-cores I promoted here will only help for a short while. I may be getting one of these motors soon from Alan Hu for testing, and I will report back]. The vast majority of affordable DD hubs I see have a stator about 28mm wide, has a stamped steel stator core, and use the thicker laminations. Rough idea of 48V speeds in a common 26″ OD diameter tire: It is the “value” leader in this category because it costs less than the other two, and it is also a little lighter with its 45mm wide stator. This is referred to as the motors “Kv” (19th century German for Konstant per voltage). If you notice that your temperature sensor is indicating your motor is getting too hot, and doing that too often? lacing their hubs to a moped rim instead of a bicycle rim, high-performance 25R and 30Q battery packs, I may be getting one of these motors soon, Here is the article on the Edge motor I tested, I like it, This is the motor that started this entire category. For builders who want all of these upgraded features, Crystalyte has “The Crown“, which can be had with a 30mm wide stator or a 40mm wide stator. They can currently be purchased in North America at Kinaye Motorsports. $150.19 $ 150. Steel stator core vs aluminum This is my new favorite DD hub for the street. 6T: 25-MPH (40 km/h) Next up is a few things that you should know, so you will understand why I am recommending these particular hubmotors, and then…we will get on to the important part…the list!

This hub can eat 1500W while its sleeping without getting warm. Seeing all the buzz about mid drives might have gotten you started thinking that the simple hub motor is dying off, but…the truth is that large direct drive (DD) hubs have remained the best option for street E-bikes that are using very high amounts of power. Many early E-bike hot-rodders still own several fried and un-sellable motors that they use as “wall art”. 48 a),60 v 200 - 400 rpm (0. 5.5T_____8.1 Rated Voltage: 72V( 48-144V Can be optional), 10. Max power 800 watt – 4000 watt (4kw). Hub Motors for Personal Electric Vehicles Click to see hub motor details. Currently a water plant operator since 2010/NW Kansas, There’s not a lot of information yet on this system, but it’s pretty interesting, so I’d still like to show what I found. Standard Motors. ), but the drop-out shoulders on the axle are 150mm wide. The number of wraps and wire thickness affects the motors’ Kv. Each stator tooth has a certain amount of airspace into which the manufacturer can wind copper wire around it. It has 130mm wide drop-out shoulders on the axle, so it fits into common bicycle frames without any spreading of the swingarm. If you see a “V1” version on the MXUS AliExpress web-page, it has the steel stamped stator support and thicker laminations. Also, if your motor is getting way too hot on a frequent basis, you might be using a motor that is too small for the job, Be aware, the Hall sensors are typically more fragile than the stator (including the fragile soldered joints), and Halls have frequently been found to die when abused with too much heat. 7T______6.3 ★★★★★4.0 out of 5 VotesRated by 273 Buyers 10 inch electric motorcycle mtor, drouput out size 1200mm, Rated power 48v,60v, 72v, 84v,96v,high speed and power.

This would be the most efficient option due to the faster motor magnet speed. Heat is the enemy when you are raising the power to find a motors’ limits. If you ordered the hub from Leaf with a rim laced to it, the price is about $20 more. Aikema 100SX front motor is a brushless,geared hub motor, light in weight,efficiency more than 80%, noise is lower than the other same normal small high speed hub motor. Max speed can be customized from 30-120KMPH. The stator width is 50mm, but also…the stator-teeth slots are deeper for more copper-fill, and all of this adds up to a motor that can take more watts. 68 a), Maximum speed can be achieved : 25 - 50 km / hr, Constant current at ideal load : 15 - 35 ampere, No-load speed: 24 v 250 rpm (0.35 a),36 v 450 rpm (0.38 a),48 v 650 rpm (0.42 a),60 v 800 rpm (0.61 a), Maximum speed can be achieved : 30 - 40 km / hr, Constant current at ideal load : 5-15 ampere. Many kinds of wheel motors could be supplied, such as brushless gearless hub motor, geared hub motor, spoke motor, ATV motor, and so on. You must either lower the amps, oil-cool the insides, ventilate the side-plates, or move up to a larger motor. 250W Central Motor, Motor with integrated controller. However, at high speed operations iron losses3 and copper losses4 including PM losses reveal that total loss is the same for both machines (p.6). At 72V and also above 72V, three names I read about quite often are Kelly, Sabvoton, and Adaptto, but…I have no experience with any of them. The two bikes namely KM3000 and KM4000 get a DeltaEV BLDC hub electric motor with the help of which, these can hit a top speed of 120kmph. This Cromotor is mounted in a smaller rim, on Martins E-Moped. Last year was an exciting time for E-bike enthusiasts who wanted a mid drive system with many new component options. The width of the stator also affects the RPMs the motor will spin at (due to the increased resistance to current flow from longer lengths of wire in the coils). You want the “V2” with the thick aluminum in the stator support, and thinner laminations. Geared hubs have no cogging due to an integrated freewheel inside the motor-case. We recommend spraying the inside of ventilated with a water-resistant coating that is designed for electric motors. While any hydraulic motor can be used for wheel drive, the speed of standard motors is far too high and their torque is far too low for direct drive to the wheels. Once the motor gets heat-soaked, you have to lower the amps, or risk a melt-down. If you are just a commuter that only needs 28-MPH (45 km/h) in a relatively flat region, you will most likely be best served by the most popular type of system, which is a geared rear hubmotor using about 50V X 25A = 1250W. You can program the amps from the controller to automatically be cut back when it gets very warm (perhaps at 160F / 71C?

If you like the motor to stay sealed up against the rain, mud, and grit from the road…you should pay a little extra to get the aluminum stator support…it is well worth it. 1★ Our 8 inch hub motor wheel power has 180w,250w,350w,500w. A quality torque arm doesn’t wear out, and a cheap one can cost you much more than just needing to buy a stronger one if the first one fails at 40-MPH. The next three motors are very heavy and can take a LOT of power. Power to weight, the geared hub motor is much better than a direct drive hub motor (read our story comparing geared and direct drive hub motors). Here is a close-up of the copper wire coils, which are wrapped around stacks of thin steel plates called laminations. The thinner 0.35mm lams are better than thicker 0.50mm ones. 17inch 3000W Electric Motorcycle Wheel Hub Motor, 9. High Quality Lithium Battery Packs for EVs, Boats Click here to see detail.

That means you would have to use an 18-FET controller to safely run 50A peaks, due to more of the input watts being converted to waste-heat. There are actually other QS motors that are larger than this (with a 273mm diameter stator), but…this 205mm-dia stator provides a level of power that stretches the already abused electric “bicycle” label. Small size and light-weight featured good performance for urban electric cycling. PRA 230 Wheel Hub Motor. Direct drive hub motors don’t have any internal gears and geared hub motors have only single gear ratio. [edit, July 2016…A new motor is now being retailed in North America. 5T: 31-MPH (49 km/h) This aluminum mass acted as a “heat sponge” that soaked up sudden and short heat spikes from using very high amps when accelerating…and then the aluminum … Motor design: Double axle out with 17inch Aluminium rim . 2. Sadly, the “H” axles have not proven to be as strong as I would have liked. Here are two identical stator-cores for RC outrunners. This looks like a motorcycle rim, but it is available in aluminum, and also with a 1.6-inch width. A custom thick stainless steel torque-plate from ES member teklektik. Although a few companies make a 250 watt direct drive motor (such as Bionx’s 250 watt motor, the same motor that goes on the Smart Bike), we strongly suggest that if you buy a bike with this size of motor that you opt for … Their H35 and H40 family of motors were affordable hubs that were used in a LOT of experiments.
