Abstract: An electric water pump with a control panel mounted in the middle of the water pump is disclosed, including a water pump volute casing, a water pump impeller, a pump cover, a water pump control panel, a rotor, a rotor cover, a housing, a rear bearing, a stator, a thrust ring, and a front bearing. The water pump volute casing is mounted on a surface at a front end of the pump cover. The water pump control panel is mounted on a surface at a rear end of the pump cover. An end opening of the rotor cover is sleeved on an outer circumference of a boss at the rear end of the pump cover.

Abstract: An electric centrifugal pump includes a water pump shell, a water sealing bearing, a water pump impeller, a spring washer, an inner motor cover, a bearing pedestal, a front rotor bearing, a motor stator, a motor rotor, a shaft of the motor rotor, a rear bearing of the motor rotor, a leading impeller, a leading impeller cover, a water pump driving control panel, a controller cover and a motor shell, and an internal forced cooling system is formed by the water inlet cavity of the water pump, an axial through hole of the shaft of the motor rotor, the leading impeller, a leading impeller cavity of the leading impeller, a spiral overflowing hole of the inner motor cover, a rotor cavity, a spiral overflowing hole of the bearing pedestal and the water pump impeller which are sequentially communicated.
