Repeat Problem 22 with the machine supplied from an 11-V line to neutral 6-Hz source.

Problem 22

A four-pole, 7.5-hp, three-phase induction motor has the following parameters

The machine is supplied from a 110-V line-to-neutral 60-Hz source.

(a) Calculate the steady-state starting torque and current.

(b) Calculate the no-load current. Neglect friction and wind age losses.

(d) If the rotor is driven mechanically to - 500 rpm, determine the mechanical power at the shaft and electrical power at the stator terminals. From these, explain the power flow in this region of operation.
