Determine the current flowing through a three phase 2 hp 400 volt motor having an efficiency rating of 93 and a power factor of 0 9.

10 hp electric motor 3 phase amp draw.

Since motors are not 100 efficient the number of amps needed to achieve the power output is actually higher depending on the efficiency. Motors ac vfd drive 3 phase power training about 90 marketing may 17 2020. The same power of motor would draw 3 5 amps at 480 v single phase but a 480 v supply could most likely be a three phase suppy and. This calculator will also give you motor amps and recommended breaker size starter size heater size and conduit size.

Written on the motor nameplate first if it is available. Example if you have 100 hp multiply by 746. 230 volts motor single phase. Motors horsepower and amps of 230vac and 460vac 3 phase 60hz electric motors here are the full load amp fla values for typical 230vac and 480vac 3 phase motors.

V l l voltage line to line. Multiply hp horsepower by 746. The are only intended to be guidelines and in all cases the full load amps of the motor nameplate should be used for final calculations. 230 volts motor 3 phase.

115 volts motor single phase. 3 phase ac motor f l a. V l n voltage line to neutral. 460 volts motor 3 phase.

Since 1 hp is equal to 746 w simply multiply the horsepower by 746 for this conversion. For example if there are three 15 amp motors in the circuit the ampacity rating of the wire feeding the. The tables below are intended to be a general guide for ac motor full load amperes. How to convert hp to amp ac 3 phases in only 3 step.

The first step to convert hp to amps is convert hp to watts. Always use the f l a. I ac2ø current ampere 2 phase. As a rules of thumb amps horsepower rating can be estimated to.

I ac3ø current ampere 3 phase. Three phase amps hp 746 e age efficiency pf 1 73 example. Always check nameplate information before designing protective devices wiring and switch gear. V dc voltage direct current.

Branch circuits that contain two or more motors must have wire in which the ampacity rating of the wire must be at least 125 of the full load current of the largest motor plus the sum of full load currents for the rest of the motors. A 1 hp motor is reckoned to draw 7 amps at 240 v single phase.
