What is a hub motor on an electric bike?
As the name implies, hub motors place the electric motor in the front or rear wheel hub to help you move the bicycle down the road. A mid-motor puts an electric motor and gears right on the pedal shaft and boosts your pedal power directly, transmitting it through a chain or belt to the rear wheel.
What type of motor is used in electric bikes?
Three-phase motors are the most popular among all the configurations and are widely used in E-bikes. The stator of a BLDC motor consists of stacked steel laminations with windings placed in the slots that are axially cut along the inner periphery.
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.
How long do hub motors last?
between 3,000 to 10,000 miles
As a result, the typical eBike gear-hub motor will have to be replaced typically between 3,000 to 10,000 miles, depending on the quality of the motor and how hard you push your eBike. Fortunately, gear-hub motors are far less expensive than mid-drive motors, and they are easier to replace and install as well.
How does a hub motor work?
A electric bike hub motor is a device that converts electrical energy into mechanical energy. It produces a rotating magnetic field by using an electric coil (the stator winding) and acts on the rotor squirrel cage type closed aluminum frame to form a magneto electric rotating torque.
Why is hub motor used?
By eliminating the main powerplant, hub motors negate the need for a heavy transmission, driveline, differential, and axles. This cuts mechanical losses, inherent in every component standing between the engine and wheel, and makes the car or truck run quieter. It also cuts weight, which makes for more-efficient travel.
