The no-load and blocked-rotor tests on a three phase, wye-connected induction motor yield the following results:
• No-load test: line-to-line voltage 400 V, input power 1770 W, input current 18.5 A, and friction and windage loss 600 W
• Blocked-rotor test: line-to-line voltage 45 V, input power 2700 W, and input current 63 A
Determine the parameters of the equivalent circuit
Definition of Magnetism Magnetism is explained as the force produced by charge particles (electrons) of magnet. A magnet is a material that obtained a magnetic field.
