LEAF Motor: Spin-Up

This is the very first spin-up test of the Less Epic Axial Flux (LEAF) motor, to about 1500rpm. The LEAF motor is a "DIY" coreless axial-flux brushless motor. More information.

The LEAF motor is the end result of a cheap set of wedge magnets that I bought. They're for "building efficient and powerful wind generators," but I was pretty sure I could make a motor out of them instead. In this video, it's getting a jump-start from a Battlebot weapon system. This controller is sensorless, so it needs a running start with this much inertia. The next test will be with full sinusoidal control and rotor position sensing.
