Get PriceThe motor current is calculated as follows. For a 3-phase supply with power rating in kilowatt (kW): For a 3-phase supply with power rating in horsepower (hp): For a 1-phase supply with power rating in kilowatt (kW): For a 1-phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor ...

Get PriceI have a small dc motor, which is rated for 12V, 3A(rated ). When the motor runs with a load 4000N, the current consumption is 1.5A. So I have to choose a 12V, 3A = 12 * 3= 36W power supply to run the motor.This is because DC power supply can supply continous 3A current without any disturbance. Now I wanted to run same motor on battery.

Get PriceJul 09, 2012 · The motor power is the sum of the shaft power and power loss due to inefficiencies in converting electric energy into kinetic energy. Motor power may be calculated as the shaft power divided by the motor efficiency.

[PDF]Get PriceCalculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts). Convert watts to kilowatts by dividing the number of watts by 1,000.

Get PriceAug 29, 2018 · If you can measure the voltage and amps flowing into the motor leads: (single phase) Amps x volts = VA, assume the Power factor is 0.8 so the KW is (VA/1000) x 0.8 on three phase, assuming balanced line currents, multiply by sq rt 3 (1.732). That ...

Get PriceMotor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. ... power. Motor selection should be based on the operating time (operating pattern). Each gearhead has maximum permissible load inertia.

Get PriceThe power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where. Active (Real or True) Power is measured in watts (W) and is the power drawn by the electrical resistance of a system doing useful work; Apparent Power is measured in volt-amperes (VA) and is the voltage on an AC system multiplied by all the current that flows in it.
