Abstract:
1. A working fluid medium temperature control system, comprising: a working fluid medium; an actuator operable on the working fluid medium; a pump for the working fluid medium; a fluid passage structure for the working fluid medium; an electric motor drivingly connected to the pump; and a control unit for the electric motor, the control unit including an inverter and an inverter controller; the inverter and the electric motor being integrated in such a way that the inverter is in heat transfer communication with the electric motor, the fluid passage structure being in heat transfer communication with the inverter, wherein the control unit is configured to adjust the temperature of the working fluid medium by allowing current to pass through coils of the electric motor in such a way that the coils generate heat to raise the temperature of the working fluid medium.
