A 3-phase induction motor can be used for different applications with various speed and load requirements. Electric motors can be found in almost every production process today. Getting the most

Table 430.249 Full-LoadCurrent, Two-Phase Alternating-CurrentMotors (4-Wire) The following values offull-loadcurrent are for motors running atspeeds usual forbelted motors and motors with normal torque characteristics. Current in thecommon conductor of a 2-phase, 3-wiresystem will be 1.41 times the value given.

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?

lower current than that shown in the table; while motors of lower speed usually take higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual f.l.c from the motor rating plate

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

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 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.
