Abstract: An electric motor for a pump is provided. The electric motor includes a motor controller configured to convert alternating current (AC) power supplied to a variable frequency variable voltage power for driving the electric motor at a motor output according to a commanded motor output. The motor controller includes an inverter configured to generate the variable frequency variable voltage power according to the commanded motor output and a microcontroller coupled to the inverter. The microcontroller is configured to control the inverter to operate at a first switching frequency when the motor output is less than a threshold motor output and control the inverter to operate at a second switching frequency when the motor output is greater than the threshold motor output, wherein the second switching frequency is less than the first switching frequency.

Abstract: A health monitor circuit for an electric machine includes a plurality of sensors, a rectifier, a memory device, and a microprocessor. The plurality of sensors includes a current transformer configured to be electromagnetically coupled to an electrical conductor that feeds a stator winding of the electric machine. The rectifier is coupled to the current transformer and is configured to convert an AC signal generated by the current transformer to a DC signal to supply power for the health monitor circuit. The microprocessor is coupled to the memory device and the plurality of sensors. The microprocessor is configured to periodically collect a stator current measurement from the current transformer and write the stator current measurement to the memory device.

Abstract: A motor controller for an electric motor for driving a blower to generate an airflow. The motor controller includes a processor and a drive circuit configured to regulate power supplied to the motor to turn the blower. The processor computes a system resistance for the blower based on a fixed set point for a first control parameter and a feedback parameter. The processor receives an airflow rate demand value and computes an operating set point for a second control parameter based on the system resistance and the airflow rate demand value. The processor controls the drive circuit based on the operating set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: An electric motor system is described. The electric motor system includes a drive circuit including an inverter configured to supply variable frequency current and a contactor configured to supply line frequency current. The electric motor system also includes an electric motor coupled to the drive circuit wherein the electric motor is communicatively coupled to a controller. The controller is configured to control the inverter to supply variable frequency current to the electric motor, thereby operating the electric motor at a motor speed, and determine, based upon at least one input parameter, a maximum potential motor speed the inverter can achieve. The controller is also configured to receive a command to operate the electric motor at line frequency current and control the drive circuit to transition from supplying variably frequency current to supplying line frequency current before the maximum potential motor speed the inverter can achieve is reached.
