Single-phase motor; Power factor

Click For Summary
SUMMARY

A single-phase motor with a current draw of 12A operates at a power factor of 60%. The in-phase component of the current (Ip) is calculated to be 7.2A, while the quadrature component (Iq) is 9.6A. The power factor indicates the ratio of real power to apparent power, which is essential for understanding the efficiency of the motor. The calculations for Ip and Iq are derived from the motor's current and power factor values.

PREREQUISITES
  • Understanding of single-phase motor operation
  • Knowledge of power factor and its significance
  • Familiarity with current components: in-phase (Ip) and quadrature (Iq)

a single phase motor draws a current of 12A at a power factor of 60%. calculate the in-phase and quadrature components of current Ip and Iq wih respect to the line voltage.


i have problem understanding the question.
is what i need to find is just the Ip (7.2A) and Iq (9.6A)

that's all?

Sounds right. But for those of us who don't work with power factor much, could you please define how the % power factor is defined? And then how you got the 7.2 and 9.6A numbers? Thanks.
