PURPOSE:To prevent an excessive increase of temperature and overcooling of a controller, by directly coupling an oil pump to a motor further providing the controller, which detects an operational condition of a vehicle to control the motor, in the vicinity of the oil pump. CONSTITUTION:An oil pump 2 is directly coupled to a DC motor 1, and each of their shafts is integrally formed. The pump 2 is connected to a control valve 3 through pipes 2a, 2b. While a controller 14 is integrally mounted to the peripheral part of the motor 1, and said controller 14 detects an operational condition of an automobile, that is, car speed and turning direction of steering to a control on and off of an electric current conduction of the motor 1. Further a conduction pipe 15 introducing working fluid of the pump 2 is provided in the controller 14. Then the motor 1 and the controller 14 are cooled by the working fluid. |
