Abstract
A method for operating a linear compressor of an appliance is provided. The method includes operating a motor of the linear compressor in order to drive a rotor of the motor. The method also include obtaining, via a controller of the linear compressor, a voltage feedback measurement of the motor. Further, the method includes adjusting, via the controller, a control setpoint for the motor based on the voltage feedback measurement and a voltage threshold. In addition, the method includes controlling, via the controller, the motor of the linear compressor based, at least in part, on the adjusted control setpoint so as to implement a flux weakening operation when the voltage feedback measurement is greater than or equal to the voltage threshold.
