Mechanical and electrical integrated drive unit i.e. electrical oil pump, for use in automatic transmission of vehicle, has magnet wire covered at end of tubular element inserted into through hole and attached to control circuit board

摘要

The drive unit i.e. electrical oil pump (1), has a partition wall (29) insulating a motor (9) of a control circuit board (27). A housing (26) accommodates the control circuit board. A magnet wire (53) of the motor is covered at an end of a conductive tubular element. The magnet wire and the tubular element are connected. The tubular element is firmly inserted into a through hole, which is formed in the partition wall such that a front end region of the tubular element projects into interior of the housing. The tubular element is attached to the control circuit board.
