Abstract: An HVAC system including a multi-capacity compressor, and a control system for the multi-capacity compressor are described herein. The control system includes an AC line voltage source, a variable-voltage variable-frequency drive, and a processor. The AC line voltage source is configured to operate the multi-capacity compressor. The variable-voltage variable-frequency drive is coupled to the AC line voltage source and is configured to operate the multi-capacity compressor at a variable speed. The processor is coupled to the AC line voltage source and the variable-voltage variable-frequency drive, and is configured to selectively couple the AC line voltage source and the variable-voltage variable-frequency drive to the multi-capacity compressor to operate the multi-capacity compressor. The processor is further configured to transmit a capacity control signal to the multi-capacity compressor. The capacity control signal is instructive to operate the multi-capacity compressor in one of a plurality of capacity settings.

Abstract: Methods and systems for controlling an electric motor using a motor controller including a processor are provided. The method includes transmitting, by the processor, a no-spin signal commanding the electric motor not to spin, receiving temperature information associated with a temperature of the electric motor, comparing the temperature information to a predetermined threshold temperature to determine whether the temperature is at a sufficient level to prevent icing, and adjusting current applied to the electric motor when the temperature measurement is below the predetermined threshold.
