Abstract
A pump-motor unit for pumping a coolant for cooling an internal combustion engine in which a centrifugal pump is connected to an electrically commutated d.c. motor to be driven thereby. A power electronic circuit is mounted on a plate and installed in the unit in connection with the d.c. motor to operate the motor in accordance with signals delivered to said power electronic circuit from an external power source. A cooling body is supported in the unit to cool the power electronic circuit by transferring heat from the power electronic circuit to the coolant. The centrifugal pump and the d.c. motor are interconnected through the cooling body.
