you need the current of motor or the KW/HP rating
20 kw
230 v 6 amps is 1380 VA which equals about 1 kW, so a 3 kW motor implies it's a 3 phase motor. It would turn over on a single phase supply in whatever direction it was first spun in, but the performance would be poor and the motor or generator could get damaged.
The frictional losses and the resistive losses generate heat in a motor
total hour = 24*7 = 168 hrs now 1 h.p. =0.750 kw 7.5h.p. =(?) Hence = 5.625 kw hence total unit = kw*hrs =5.625*168 =945kwh NOw cost = unit/hrs *motor running hrs =6 Rs for indust * 945 =5670 Rs

How to calculate motor kw for cranes
To convert AC tonnage to kVA and kW, use the following formulas: For kVA: kVA = (tonnage x 3.517) For kW: kW = (tonnage x 3.517 x power factor). Remember to consider the power factor of the system when converting from tonnage to kVA and kW.
To convert horsepower (hp) to kilowatts (kw), you can use the conversion factor of 0.746. Therefore, for a 100 hp motor, the power in kilowatts would be 100 hp * 0.746 = 74.6 kW.
Typical motor and belt efficiencies: * Motor 1kW - 0.4 * Motor 10 kW - 0.87 * Motor 100 kW - 0.92 * Belt 1 kW - 0.78 * Belt 10 kW - 0.88 * Belt 100 kW - 0.93Depending on the motors input , we can measure the voltage consumed by a ceiling fan.Normally , household fans consume 200 - 400 watts of energy.hope this helps =)
