What is an Electric Water Pump?

As we all know, an electric water pump is an coolant pump with an electronic control drive unit used in automobiles’s thermal management system to cooling the engine, battery, or motor control unit.

Electric water pump is mainly composed of three parts: a flow unit, a motor unit, and an electronic control unit. The working state of the pump can be adjusted through the electronic control unit, such as: controlling the start/stop of the pump, flow control, pressure control, anti-dry-run protection, self-maintenance and other functions. The working state of the pump can be controlled by an external signal. As a brushless DC pump, the power of an automotive electric water pump is relatively small, generally below 1000W, and is usually driven by a BLDC motor.
