How does a VFD improve the life of an electric motor?
A. By reducing the amount of current flowing through the motor B. By reducing the mechanical stress on the motor C. By reducing the heat generated by the motor D. All of the above
Explanation: A VFD can improve the life of an electric motor by reducing the amount of current flowing through the motor, reducing the mechanical stress on the motor, and reducing the heat generated by the motor. By adjusting the speed of the motor to match the load on the system, the VFD can reduce the current flowing through the motor, which can reduce the wear and tear on the motor. Additionally, by reducing the mechanical stress on the motor, the VFD can reduce the wear and tear on the motor, which can also improve its lifespan. Lastly, by reducing the heat generated by the motor, the VFD can improve the life of the motor by reducing the thermal stress on the motor.
