B.W.D. Scooter Test Drive #1

The B.W.D. Scooter is an electric kick scooter with Both Wheels Driven by custom-built brushless DC hub motors. For more information, visit:
http://web.mit.edu/first/scooter

The hub motors built into each wheel are 3-phase, 14-pole brushless outrunners; the inside of the motor is stationary and the outside spins. The design is based heavily on Charles Guan's Project RazEr. Each motor is made of stacks of thin, laser cut steel laminations donated by Proto Laminations. They are direct-drive, so there is no need for chain or belt, but a practical consequence of this is an inherent 1:1 gear ratio. To get a lot of torque with no gear reduction, we chose to use two motors and strong NdFeB magnets.
