B.W.D. Scooter Custom BLDC Motor - Test #1

Fast-forward to 1:50 to see it spinning!

This is test #1 of the B.W.D. Scooter's first custom-built motor. The scooter is this year's Edgerton Center Summer Engineering Workshop project. B.W.D. stands for either "both wheel drive" or "brushless wheel drive," since the Razor-style scooter will have two integrated BLDC hub motors.

The hub motor is built from scratch using laser-cut steel laminations donated by Proto Laminations. It has 12 slots and 14 neodymium block magnets (see LRK winding motors). The inspiration came from Charles Guan's Project RazEr.

This test was at 36V. The first 1:50 is us trying to find the right permutation of phases, since the motor is electronically commutated based on signals from hall effect sensors. The next step is to add tread and...oh yeah...build the scooter.
