Abstract
A hub motor includes a hub motor body, an axle extending into the hub motor body, a rotor coupled to the outer housing, a stator within the rotor and coupled to the axle, and a brake within the hub motor body. The brake may include a brake pad spring-biased into braking engagement and moved out of braking engagement by an electromagnetic coil, such that the brake will fail into a braked state.
