Question

Based on the motor nameplate below, when operated at the rated voltage and current, determine the following:

a. The real power, P, reactive power, Q, and apparent power, S, used by the motor.

b. Sketch an equivalent circuit to model for the motor.

c. The efficiency of the motor (calculated from shaft power/real power in).

d. What value of capacitor would you use to correct the power factor to 1?

e. Sketch a vector diagram showing the phasor current in the motor, the phasor current in your compensation capacitor and the total phasor current. (Assuming that the voltage phase is zero.)

f. How much torque would the motor produce at the rated RPM?
