PURPOSE: A hydraulic pump with an integrated electric motor is provided to improve the cooling effect of an electric motor by simultaneously cooling a rotator and a stator in the electric motor with using oil. CONSTITUTION: A hydraulic pump with an integrated electric motor comprises a hydraulic pump(11), an electric motor(12), a housing body(13), an oil cooling part(14), and a control box. The hydraulic pump forms hydraulic pressure in the hydraulic working oil. The electric motor converts electric energy to mechanical energy. The housing body has a receiving space for receiving the hydraulic pump and the electric motor together. A flow path for flowing hydraulic working oil is formed inside the housing body. The oil cooling part cools the hydraulic working oil. The control box is coupled to the housing body and controls the operation of the hydraulic pump, the electric motor, and the oil cooling part. Some of the hydraulic working oil flowing into the housing body flow into the electric motor. |
