More Information
Summary:A chiller system is provided which comprises a compressor, a synchronous motor and a controller. The compressor is configured to circulate a refrigerant between an evaporator and a condenser in a closed refrigerant loop. The synchronous motor is configured to drive the compressor, the motor comprising a stator winding and a rotor. The controller is configured to estimate a flux linkage of the rotor. The controller is further configured to provide a control signal to the motor based on the estimated flux linkage.
