Abstract
An electric coolant pump includes an outer housing, a motor, an impeller, and an electrical control unit. The outer housing includes a first housing portion, a second housing portion, and a partition plate integrally formed. The partition plate is disposed between the first housing portion and the second housing portion. The motor is received in the first housing portion. The motor includes a sealing sleeve, a stator disposed on an inner wall surface of the outer housing, and a rotor rotatably received in the sealing sleeve. The impeller is driven by the rotor of the motor to drive a coolant to flow. The electrical control unit is received in the second housing portion and electrically connected to the motor. The electrical control unit and the impeller are respectively located at two opposite ends of the motor.
