Motor Current Calculator
Motor Current Calculator , This Web App will help you calculate Single Phase or Three Phase Motor Output Current .
User will need to input the parameter listed below to Calculate the Motor Current Output
- Motor voltage
- Phase Type ( Single Phase or Three Phase)
- Motor Power Rating ( KW/ HP)
- PF
- Motor Efficiency
Motor Current parameters
- Voltage (V). 3 Phase -> Phase to phase Voltage Single Phase -> Phase to Neutral Line Voltage
- Motor Power Rating . (KW / HP)
- Power factor (cosΦ). Rated power factor of the motor.
- Efficiency (η). Eficiency of the motor.
Formulae as Below
| Motor Power Rating Unit | Single Phase | Three Phase |
| KW |
1000 x P(KW) / (Voltage x cosΦ x η)
|
1000 x P(KW) / (√3 x Voltage x cosΦ x η) |
| HP | 745.7 x P(HP) / (Voltage x cosΦ x η) | 745.7 x P(HP) / (√3 x Voltage x cosΦ x η) |
Example Calculation :
- Voltage (V). 3 Phase -> 400v
- Motor Power Rating . (KW ) ->20KW
- Power factor (cosΦ). ->0.5
- Efficiency (η). ->60%
Motor Current = 1000 x P(20KW) / (√3 x 400 x 0.5 x 60%)
Motor Current = 96.23A
