Motor Current Online Calculator


(As the supply voltage cannot be kept at 380 V or 220 V, so the current changes with the voltage. )

Online calculation of motor current power

Motor current calculation formula:

Single item: \(I= \frac {P}{220×Cosφ·η} \)

Three items: \(I= \frac {P}{1.73×380×Cosφ·η} \)

(The single-item motor power factor and efficiency are both 0.75, and the three-items motor is 0.85 each).
