  • Publication number: 20240291412
    Abstract: A variable frequency drive motor system and method with a single variable frequency drive controller controlling multiple synchronous reluctance motors in an open-loop mode using volts-per-Hertz control. Each motor includes a rotor including three or more curved, spaced-apart barrier slots extending longitudinally through each quadrant of the rotor. The rotor also includes a conductive cage including a plurality of conductive rotor bars contained within the barrier slots and also extending longitudinally through each quadrant, and conductive end rings located at opposite ends of the rotor and electrically connected to the respective ends of the rotor bars. The controller controls speed and torque by varying input frequency and voltage in an open-loop mode by adjusting the voltage magnitude of an inverter's output to each motor to match a required load torque in a volts-per-Hertz relationship. An operator interface allows for starting, stopping, adjusting, and otherwise controlling the operation of each motor.
