Induction Motor Speed: Electrical vs Mechanical

Click For Summary
SUMMARY

The discussion clarifies the distinction between electrical speed and mechanical speed in induction motors. Electrical speed refers to the speed of the magnetic field generated by the AC frequency, while mechanical speed is the actual speed of the rotor. The relationship between the two is defined by the formula: electrical speed equals the number of pole pairs multiplied by mechanical speed. This fundamental understanding is crucial for anyone working with induction motors.

PREREQUISITES
  • Understanding of induction motor principles

Hello Everybody,
Can anyone explain, what is thee difference between 'electrical spped' and 'mechanical speed' of rotor in an induction motor? what do they signify? Many literatures say that electrical speed is no of pole pairs times mechanical speed, if somebody can explain...
Thanks
