WebAug 4, 2008 · If we assume the motor is only 50% efficient then, to produce 3 hp, it will have to be supplied with electrical power of at least 2 x 2.25 = 4.5 kW. Since Power P (Watts) = V (Volts) x I... WebInstead of that by calculating no-load current of the 50HP motor (it will be 6 to 10 Amps), you can design low rated starting equipment (i.e starter, cables etc) to start the motor at the maintenance floor itself. The no-load current is used to improve the winding resistance (to improve the megger value).
WebJan 23, 2024 · The first step to convert HP to amps is to convert HP to watts. Since 1 HP is equal to 746 W simply multiply the horsepower by 746 for this conversion. Watts = Horsepower × 746 as we know all motors are not 100 % efficient efficiency usually from 70 % to 99 %. Hence Watts = watts/ η Convert to Amps WebNov 24, 2024 · An operating three phase motor has voltages measured with a voltmeter on each phase of 453, 458, and 461 volts, amperage measured on each phase with an ammeter are 14.1, 13.9, and 13.8 amps, power factor was measured as 0.82. The average voltage is 453 plus 458 plus 461 divided by 3 which equals 457 volts.
