Patent number: 8476795Abstract: In a circuit substrate of an electric water pump, a Hall IC can be mounted on a circuit substrate at an optimum position in a stable and durable state. The electric water pump includes a motor housing, a stator constituted by a stator core covered by a resin insulator and a coil, a circuit substrate, a holder 6 mounted on the circuit substrate, and a Hall IC mounted on the holder. A holder accommodation portion, into which the holder is inserted, is formed in the insulator, the stator is disposed in and fixed to the motor housing, the circuit substrate is appropriately mounted on the motor housing, and the holder 6 is inserted into and supported by the holder accommodation portion.Type: GrantFiled: April 11, 2011Date of Patent: July 2, 2013Assignee: Yamada Manufacturing Co., Ltd.Inventors: Keisuke Wakabayashi, Masanori Umeno, Nobuyuki Kabasawa

Patent number: 7240656Abstract: An object of the invention is to provide an electric oil pump with greatly improved operation, increased endurance, and extended service life of an Oldham's coupling connecting a drive shaft that rotates a rotor in a pump housing and a motor output shaft in a motor housing. The electric pump comprises a pump housing having a rotor and a drive shaft for rotatably supporting the rotor, and a motor housing connected to the pump housing and having an output shaft connected to the drive shaft via an Oldham's coupling. The pump housing is provided with a coupling chamber for accommodating the Oldham's coupling, and a linking channel for transporting the leaked oil from a rotor chamber accommodating the rotor of the pump housing to the coupling chamber.Type: GrantFiled: December 22, 2005Date of Patent: July 10, 2007Assignee: Yamada Manufactoring Co., Ltd.Inventors: Kosuke Yamane, Masanori Umeno, Keisuke Kashiwa, Hirotaka Eno
