100 Hp Electric Motor Amp Draw

Multiply hp horsepower by 746.

100 hp electric motor amp draw.

How to convert hp to amp ac 3 phases in only 3 step. Example if you have 100 hp multiply by 746 and you get 74600. 1 hp 0 745 kw. In the calculator above fla is rla 25.

Amps hp 746 v η pf thus the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For a 1 horsepower hp motor the load should typically be in the range 1 2 to 1 hp with maximum efficiency at 3 4 hp. Locate the terminals on the ac motor.

For example let s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90 efficiency. Multiply the ac voltage by the motor efficiency the power factor and the square root of 3.

The conversion from amps a measure of electric current to horsepower a measure of power output by a motor can be done using a fairly simple formula. Fla full load amps amount of current drawn when full load torque and horsepower is reached for the motor fla is usually determined in laboratory tests note. Single phase ac calculations. Where the circuit breaker rating determined by t430 52 is not sufficient for the starting current inrush current experienced by the motor the electrician is allowed to increase the circuit breaker size even further up to a maximum of 400 for loads that do not exceed 100 amps.

Put on rubber gloves to protect you from an accidental electric shock. Find the current passing through 24 volt 1 2 hp motor having an efficiency of 95. Note that most electric motors are designed to run at 50 to 100 of rated load and that maximum efficiency usually is near 75 of rated load. Thus horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor divided by 746.

Horsepower i a v v η pf 746. The positive terminal is labeled and the negative the wires connected to the ac motor are colored red for positive and black for negative. Dc amps hp 746 e age efficiency example. Rla running load amps current drawn during normal operation of electric motor.

Current 0 5 746 24 volt 0 95 16 35 amps.
