The following table shows the load current drawn by three phase motors of various power ratings and supply voltages. To read this table, look up the power of your motor in the either of the yellow columns and then read along to the appropriate voltage current. The value indicated is the full load current in amps. Power.

Abstract and Figures. Introduction: The three phase induction motors are simple in construction, rugged, low cost and easy to maintain. They run at a constant speed from no-load to the full load

An electric motor has specifications: voltage is 380 V, 3 phase, frequency is 50 Hz, 1500 rpm, cos phi is 0.8 and real power on the name plate is 22 kW. Convert to HP (Horse Power) and calculate, how many current of electricity will flow into the motor?

exists for low voltage three-phase asynchronous motors. holes (see diagram below). For more information, see ABB's Low Voltage Motors Manual.

Most electric motors are designed to run at 50% to 100% of rated load. Figure 3 Relationships Between Power, Current, Power Factor and Motor Load.

3. Conductors with compact and compressed stranding have about 9 percent and 3 percent, respectively, smaller bare conductor diameters than those shown. See Table 5A for actual compact cable dimensions. 4. The IACS conductivities used: bare copper = 100%, aluminum = 61%. 5. Class B stranding is listed as well as solid for some sizes.

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

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.
