you need the current of motor or the KW/HP rating
20 kw
The frictional losses and the resistive losses generate heat in a motor
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.
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 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.
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.
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 =)
