classes IE1, IE2 and IE3 for low voltage three phase motors in the power range from 0.75 kW to 375 kW (2, 4 & 6 Poles). In today's world where requirement of electrical energy is considerably increasing due to automization, innovations, huge productions and many other factors, while on the other hand the resources for generating this energy are

Based on Motor Horsepower Motor horsepower and motor Full Load Amperes (FLA) shown are taken from NEC® Tables 430.248 through 430.250 covering standard speed AC motors with normal torque characteristics. Fuse ratings for motors with special characteristics may need to vary from given values. If motor running protection will be provided by the

Wye connected 12-lead motors differ from 9-lead three-phase dual-voltage motors in that none of the coils is permanently connected and therefore all can be tested separately. Although this increases the time required to test every possible combination; it does allow you to better pinpoint exactly where a failure may occur in the motor.

The winding with seriously aged insulation should be exchanged. 4. The induction motor sound is abnormal. In two-phase operation, there is a buzz sound. Restart the motor after shutting down. If the motor doesn’t rotate in two-phase operation, find the reason for phase loss and eliminate it. The three-phase current is unbalanced.

phase 3 apparent power = 82 x 230 = 18,860 VA = 18.86 kVA Total three phase power = 18.4 + 16.1 + 18.86 = 53.36 kVA Similarly given the power in each phase you could easily find the phase currents. If you also know the power factor you can convert between kVA and kW as shown earlier. Unbalanced Voltages
