1. A four-pole, three-phase induction motor rotates at 1,700 r/min when the load is 100 N-m. The motor is 88 percent efficient.
a. Determine the slip at this operating condition.
b. For a constant-power, 10-kW load, determine the operating speed of the machine.
c. Sketch the motor and load torque-speed curves on the same graph. Show numerical values.
d. What is the total power consumed by the motor?
2. Find the speed of the rotating field of a six-pole, three-phase motor connected to (a) a 60-Hz line and (b) a 50-Hz line, in revolutions per minute and radians per second.
