A three-phase 3.7 kW/5 hp, 1420 rpm, delta connected squirrel cage induction motor is used to drive a constant power load. It has its per-phase equivalent circuit parameters referred to stator: R1=5.392, R2=5.722, X, =X2=8.222, Rm=20002, and Xm=192 2 at rated voltage and frequency of 415 V, 50 Hz. At 360 V, 50 Hz, it has Rm=2100 2 and Xm=2402. Calculate its (a) supply current, (b) losses, and (c) input power at rated speed and voltage. Calculate its (d) supply current, (e) losses, and (f) input power at rated speed and 360 V, 50 Hz. For constant output power, consider new slip=rated slipx (Vrated VNew) approximation,

Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.
