3hp electric motor amps.

Amperes amps and horsepower hp are the electric motor s rating methods. To find this divide the horsepower by the efficiency η in decimal form. Watts watts η. Dc motors full load currents full load amps in 120 and 240 volts dc motors.

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. Sku s 68302 brand smith jones keyway 3 16 in. Electrical electrical units amps and electrical wiring wire gauge and awg electrical formulas and motors. Electric motor calculator calculate amps hp and kva electric motor efficiency calculate electric motor efficiency electrical induction motors synchronous speed the speed at which an induction motor operates depends on the input power frequency and the number of electrical magnetic poles in the motor.

Motors built for especially low speeds or high torques may have higher full load currents and multi speed motors will have full load currents varying with speed. Ac volts 240 amperage amps 12 26 horsepower hp 3 speed max 3600 rpm shipping weight 41 70 lb. Conductors supplying this motor are required to be 125 of flc which. Electric motor wiring 480 volt electrical motor wiring data nema amps starter size hmcp size for motors ranging 1 2 to 500 hp.

After the power has been converted to watts use the watt s law formula to find current in amps. Thus horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor divided by 746.
