PURPOSE: To provide an electric oil pressure pump that has a good control mechanism for controlling delivery fluid pressure and flow quantity of the pump.

CONSTITUTION: A speed sensor 46 and a pressure sensor 56 are arranged in a motor/pump unit. In order to compare with the corresponding command signals, electric signals being respective functions of motor speed and pump delivery pressure are supplied. The pump speed sensor 46 is supported by an intake inducer of the pump and includes a detection assembly 52. Periodical signals indicating angle speeds of the pump are supplied to a pump controller 54 operated by a microprocessor. A pump delivery port 28 is connected to the pressure sensor 56, and the signals indicating the pump delivery pressure are supplied to the controller 54. A temperature sensor 58 is installed in a housing 12, sensor signals indicating temperature of oil pressure fluid of casing pressure surrounding the motor and the cylinder block are supplied to the controller 54.
