The invention relates to an electric hydraulic pump for hydraulic control and an oil supplying system provided with the same. The electric hydraulic pump for a transmission includes: a motor includinga motor cover, a motor case coupled with the motor cover, and a stator and a rotor disposed within the motor cover and the motor case; and a pump including a pump case forming a pump chamber, and a gear rotor which is disposed within the pump chamber, connected with the rotor through a motor shaft and receives rotational power of the motor. In particular, a plurality of oil circulation holes areformed in the motor cover and a connecting hole is formed in the motor cover corresponding to the pump case, and an oil flow channel is formed within the pump case for connecting the connecting hole and an oil inlet of the pump chamber. 本发明涉及用于液压控制的电动油泵和设置有该电动油泵的供油系统。具体地，一种用于变速器的电动液压泵包括：电机，其包括电机盖、与电机盖接合的电机壳体、以及设置在电机盖和电机壳体内的定子和转子；以及泵，其包括形成泵腔的泵壳体、以及设置在泵腔内的齿轮转子，所述泵通过电机轴与所述转子连接并且接收所述电机的旋转动力。具体地，多个油循环孔形成于所述电机盖，并且连接孔形成在对应于泵壳体的电机
