Abstract

A motor unit system is described. The motor unit system may include a housing with a circular cross-section and a brushless direct current motor with a shaft and a winding, the shaft extending from inside the housing to outside of the housing. A motor controller may also be contained within the housing, along with a first connector and a second connector. The first connector may include a first pair of contacts electrically coupled to the motor controller at a power supply input. The second connector may be adapted to operate independently from the first connector, and may include a second pair of contacts electrically coupled to the motor controller at a control input.
