MAC motor is the best geared motor of the market. 32 magnets for maximum torque and silent.

Types of Motors: Hub Motor vs. Mid-Drive Motor Though there are a few other types of electric bike motors available, hub motors and mid-drive motors are the most popular options, so we will delve into the details of those two here. More common than mid-drive motors, hub motors are installed directly inside the hub of the bike's front or rear wheel.

This motor includes an internal 6-pole speedeometer sensor so it can use a CA-DP device and not require an external speedo pickup. Includes 3 piece CNC'd torque arm with inner spline made from 7075 alloy. For more details see the GMAC Info Page. Bearings: I see elsewhere the Gmac is a mac geared hub motor modified to have regenerative braking. I prefer a standard MAC as I pedal myself a lot and use the one-way clutch 70% of the time to be free of drag. But people have different needs. A clutchless model may be just the thing for a dedicated commuter e-bike.

The GMAC is probably the best geared hub motor you can get right now. It has proper sized 10mm axles and a built-in torque arm, which means that it's probably going to have the widest compatibility with existing bikes. Most hub motors use 14mm axles with the sides ground down to 10mm so it can slot into drop outs.

5. METHEDOLOGY The main advantage of the clutch is more control on street.

Includes 3 piece CNC'd torque arm with inner spline made from 7075 alloy. For more details see the GMAC Info Page The result is the GMAC, which offers a new clutchless design and thus enables regen braking, even with a smaller, lightweight geared hub motor. gmac motor 1 While regenerative braking in e-bikes usually only offers around a 5% increase in range during city driving, its braking benefit is often more important than its efficiency gains. GMAC Clutchless Geared Hub Motor, Standard 10T (8.1 RPM/V) winding. This motor includes an internal 6-pole speedeometer sensor so it can use a CA-DP device and not require an external speedo pickup. Includes 3 piece CNC'd torque arm with inner spline made from 7075 alloy. For more details see the GMAC Info Page.

We hope our BTN cheap kits can help I've pretty much settled on a MAC or GMAC motor and was looking at the Grin kit vs the EM3V kit vs a bit of each. My priorities are relatively lightweight, would like to have ~1500w acceleration available, but would use that rarely, low-maintenance, torque sensor (Sempu looks best here) and will generally commute on the fairly flat bike path so not a lot of braking. I have a geared hub motor running 52v 20a , and tops out at about 28mph on a 700 x 38c tire. I'd like to get a little more speed out of it, but can't go too big on the torque. So, it seems that running 72v and 12~15a would be a way to do it, after repla GMAC clutchless geared hub motor and the GCD, can be run with a throttle or as a speed pedelec; Regular geared drivetrain running a Direct Drive hub motor or geared-hub-motor (and this can include a torque sensing system for a speed pedelek system; Yes, There were no topics or threads in this section of the new forum yet, so I'm posting a video I did some time ago, that will probably be helpful to some with existing geared hub motors, at some point, and also help with choices between geared versus direct-drive hub motors. 2019-04-01 · HENGTAI MOTOR.

Clutches and brakes are used to adjust the speed of rotating elements. A variety of technologies are used for clutches and brakes including (in order of increasing force) pneumatic, electromagnetic, mechanical, and hydraulic. Key factors to consider include torque, diameter, response time, power budget, and cost. The GMAC motor without a clutch has a no-load drag that varies from 1.0- 1.5 Nm with sheel speed, which is more than a typical direct drive hub motor (0.6-1.0 Nm). For most riders this would be a detectable amount of extra resistance when pedaling the bike, and it's one of the reasons that geared hub motors have all tended to have a freewheel built in.
