This document presents the equivalent circuit diagram of an induction motor and summarizes the results of various tests on a 5 HP, 4-pole, 220 V, 3-phase, 60 Hz induction motor with a B-type winding design and nominal current of 12.9 A.
The tests included:
1) Stator resistance (CD) test to measure stator resistance
2) No-load (vacuum) test to measure nominal voltage
3) Blocked rotor test to measure nominal current
The test results found:
1) CD voltage = 13.8 V
2) No-load voltage = 220 V, current = 13.0 A, power = 200 W
