But, that does not get you 300 amps because whatever you hook up draws it's amps on each phase. 5 1140 32 2. Order code: 25425. 73 Power(watts) = Voltage x Current x 1. The motor is 92% efficient at voltages between 24 to 96 VDC. A resolver should only be chosen if the environment in which it will be used requires it. That should give you a general idea of the typical current draw of such a motor. The P (power) in kW (kilowatts) is equal to square root of 3 times the PF (power factor) times the phase I (current)in A (amps), times the line to line RMS voltage VL-L in V (volts) divided by 1000 Calculation with line to neutral voltage. And also since three phase uses three live wires, so even if one or two phases are down, you can still get power on the phase that is running. 732 x Volts x Amps x PF 3 PF = Input Watts / Volts x Amps x 1. Easy enough. The following calculators compute reactive power in a three-phase system based on KW and KVA or voltage, current, and power factor. In the case of three phase AC (Alternating Current) operation, the most widely used motor is a 3 phase induction motor, as this type of motor does not require an additional starting device. (lag) and the 3-phase line voltage is 3,300 V. The three-phase motor uses a three-phase inverter to control the motor and meet the dynamic torque requirement in compressor motors with high efficiency.
