Rated current for single phase motor

• I: Current absorbed by the motor. (A)
• P: Motor rated power, shaft power. (W)
• U: Tension. (V)
• η: Efficiency. (%)
• cos ϕ: Power factor before compensation.

Grades:

Full load current values correspond to motors operating at usual speed and motors with normal torque characteristics. The voltages shown are the nominal ones of the motors.

For operating voltages other than those shown here, multiply the current obtained by the standard voltage and then divide by the required operating voltage.

Adaptation of table 430.248 of the NEC 2017. Estimated efficiency values with a power factor of 85%.
