Calculate amps, hp and kVA for electrical motors. The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa. Calculate Current (amps)
Voltage: V = I x R. Online calculator for electric motors in the areas of electrical power, torque, slip, cable cross-section and energy savings.
This formula is derived from the basic power calculation for three-phase AC motors, where \( \sqrt{3} \) is a constant for three-phase systems. Example Calculation. Suppose you have a motor running on a 400V supply with a current of 20A and a power factor of 0.85. The motor capacity can be calculated as:
The consumed electrical power of the motor is defined by the following formula: Pin = I * V. where P in – input power, measured in watts (W); I – current, measured in amperes (A); V – applied voltage, measured in volts (V). Motors supposed to do some work and two important values define how powerful the motor is.
The diagram below can be used to estimate power vs. amps and voltage when charging electrical vehicles with DC or single/three phase AC current. Download and print EV - Electrical Vehicle Charging chart.
