Electric coolant pump

An electric motor drives the coolant pump. The power output of the electric motor (400 Watts) is controlled by a control electronics circuit. This control electronics circuit is connected via the bit-serial data interface with the DME (Digital Engine Electronics). The DME uses the load, operating range and the data of the temperature sensors to determine the required cooling power. The DME sends to the corresponding signals for control of the coolant pump to control electronics circuit. The coolant pump's motor is immersed in flowing coolant. This cools the motor and the control electronics circuit. The coolant also lubricates the bearings of the electric coolant pump.
