摘要： In an electric pump unit in which a single shaft (main shaft) functions both as a rotation shaft of a pump section and that of a motor section, a rotor of a motor has a structure in which a magnet is embedded in a rotor core (IPM structure). According to the configuration, in the electric pump unit of the invention, it is not required to dispose a protective ring in the periphery of the rotor core. In addition, rotation of the main shaft can be supported by the inner-diameter face of the stator core. Accordingly, the electric pump unit of the invention can be configured as an electric pump unit which is lighter, more compact, and more economical as compared with a conventional product.

摘要： In a method of operating an electric motor which drives an auxiliary oil pump for supplying a hydraulic pressure of an ATF to a transmission, only at an idle stop of an engine via a rotation shaft pivotally supported by ball bearings, the electric motor is rotated at a very low speed or in an intermittent manner when an automobile is traveling and the auxiliary oil pump is not used. According to the configuration, the electric motor is slightly rotated during when the automobile is traveling, whereby impressions are prevented from being formed on the ball bearings.

摘要： An electronic controlled coupling including a wet-type multiple disc clutch, a coupling case, a hydraulic chamber, an oil pump, an electric motor, an electric control unit, and a supply passage for supplying hydraulic pressure. The coupling case accommodates the wet-type multiple disc clutch and contains oil. The oil pump driven by the electric motor is connected to the coupling case. The outlet of the oil pump is connected to the hydraulic chamber of the wet-type multiple disc clutch with the supply passage therebetween. The electric control unit controls the speed of rotation of the electric motor through a motor driver so that the pump discharge pressure is equal to an operating pressure required for the wet-type multiple disc clutch. The electronic controlled coupling performs a complete coupling mechanism increasing the durability as a coupling and a compact and simple structure enhancing the flexibility in designing.
