Abstract

A motor unit system is described. The motor unit system may include a housing with a brushless direct current motor and a motor controller contained within the same housing, where the motor controller comprises a printed circuit board, and an integrated circuit mounted on a component side of the printed circuit board, and a base plate at one end of the housing. The integrated circuit may be interposed between the base plate and the printed circuit board.
