How many amps does a 60 hp motor draw? - Repair and maintenance

How much current does a motor draw? Calculate the amps used by dividing the wattage by the voltage. For example a 500-watt motor — running on 50 volts — will draw 10 amps. A motor with the same wattage — running on 20 volts — will use 25 amps. This is the theoretical number of amps used by the motor. IT IS INTERESTING: Does water get

How to Size a Circuit Breaker for a Motor Properly & Accurately?

Its voltage is 220V, while the power factor is 0.8 with an efficiency of 90%. With these values in mind, we'll arrive at the following equation: I = (25 x 746) / (√3 x 220 x 0.8 x 0.9) The total pullout current is 67.98 amperes. 2.
