Full-load current
27.36 A
Estimated running current at rated output power, rated voltage, configured power factor, and efficiency.
Calculator preliminar
Motor current calculator
Estimate motor full-load current, electrical input, apparent power, and startup current for single-phase and three-phase AC motors.
Assumptions used by this calculator
- Motor power is treated as shaft output power, then converted to estimated electrical input using efficiency.
- Power factor and efficiency are assumed constant at rated load.
- Starting current multiplier is a planning estimate only. Soft starters and VFD systems can be much lower than direct-on-line starting.
- Final cable, breaker, overload, and starter decisions should still be checked against the motor nameplate and applicable code.
Starting current
164.19 A
Estimated inrush current based on the configured starting-current multiplier.
Electrical input
16.3 kW
Approximate electrical input power required to deliver the configured motor output.
Apparent power
18.96 kVA
Estimated apparent power demand using the configured power factor.
