A 2-speed Squirrel cage induction motor has a lower speed of 1400 RPM. The other speed will be:

  1. 700 RPM
  2. 1980 RPM
  3. 2800 RPM
  4. 3675 RPM

Correct answer: 3. 2800 RPM

Explanation: Multispeed winding motors have stator windings that be reconfigured to obtain a different number of poles. The low-speed winding is wound for more poles than the high-speed winding. Two-speed induction motors have two speeds of which one is half of the other.
