Abstract: A system including an electric motor of a compressor system and a controller is disclosed. The electric motor includes an inverter and a contactor to operate the electric motor at variable frequency power and line frequency power, respectively. The controller is configured to determine that the electric motor needs to be operated using the line frequency power instead of the variable frequency power in accordance with a load condition on the system. The controller is configured to determine a time to generate a signal to close the contactor by energizing a coil of the contactor, and initiate transition of the electric motor to operate using the line frequency power instead of the variable frequency power by applying the signal to close the contactor at the determined time.

Abstract: An electric motor system is provided. The electric motor system includes a drive circuit including an inverter configured to supply variable frequency current over a first duration and a switch configured to supply line frequency current over a second duration. The electric motor system further includes an electric motor coupled to the drive circuit and a controller communicatively coupled to the drive circuit. The controller is configured to control the inverter to supply variable frequency current to the electric motor over the first duration, determine to control the drive circuit to transition from supplying variable frequency current to supplying line frequency current, measure at least one parameter of the inverter, compute, based on the at least one measured parameter, an adjustment to a default parameter to enable the inverter to reach a threshold output frequency, and operate the inverter based on the computed adjustment to the default parameter.
