How do hub motors work?

How does an eBike hub motor work?

In the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. In this way, high power and torque is developed by a smaller motor that weighs less.

How do you drive a hub motor?

The direct drive hub motor is about as simple as things get. Imagine taking an electric motor, but holding the axle and letting the body of the motor spin. Now lace a bicycle rim onto this spinning motor body and there you have it, no moving parts other than the wheel itself.

How long do Hub Motors last?

Electric Bike motors will generally last a long time and some types of motors, like the direct drive hub motor can last upwards of 10,000 miles or more. You’ll probably be replacing brake pads and tires multiple times, chains, cassettes, and the battery before the motor.

Instead of having one motor powering all the wheels using gears or chains, they build a motor directly into the hub of each wheel—so the motors and wheels are one and the same thing. That’s what we mean by a hub motor. Photo: Left: The hub motor of an electric bike.

Which is better hub motor or mid-drive motor?

Mid-drive motors are known for higher performance and torque when compared to a similarly powered traditional hub motor. One key reason why is that the mid-drive motor drives the crank, instead of the wheel itself, multiplying its power and allowing it to better take advantage of the bike’s existing gears.

Can you run a hub motor without a controller?

Re: Way to test run a hub motor without the controller? Assuming its a brushless motor (3 wires ?) , then no, you need a controller to test run it. But controllers are easy and cheap to get so just look through Ebay or similar for another.
