Abstract: A motor control system for heating, ventilation, and air conditioning (HVAC) applications is described. The motor control system includes a thermostat and an electronically commutated motor (ECM) coupled to the thermostat. The ECM is configured to retrofit an existing non-ECM electric motor included in an HVAC application and to operate in one of a plurality of HVAC modes. The HVAC modes include at least one of a heating mode, a cooling mode, and a continuous fan mode. The HVAC mode is determined based at least partially on outputs provided by the thermostat.

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 HVAC system including a compressor, a fan, and a bypass circuit for the compressor and/or fan are described herein. The bypass system includes a combination of circuits that work together to allow an electric machine to continue operation. The bypass circuit can be coupled to a failed drive to continue to operate the HVAC system if the drive or another part fails.

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.

Abstract: A diagnostic device for an electric motor includes a device memory, a wireless communication interface, and a processor. The interface is coupled to the device memory and retrieves, over a first wireless channel, operating data stored in motor memory on the electric motor. The interface transmits, over the first wireless channel, operating parameters to the electric motor. The operating parameters define a test routine for the electric motor. The test routine, when carried out by the electric motor, generates test data corresponding to the operating parameters and that is written to the motor memory. The interface retrieves, over a second wireless channel, the test data stored in the motor memory. The processor is coupled to the device memory and the interface. The processor processes at least the test data to diagnose the malfunction.
