Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe speed of the induction motor can be controlled by the following methods:
1) V/f control (or) frequency control
2) Changing the number of stator poles
3) Controlling supply voltage
4) Changing winding resistance by adding rheostat in the stator circuit
We can apply all these methods to slip ring induction motors, but the adding resistance in the stator circuit is not possible for squirrel cage motors as rotor bars are short-circuited using end rings.Last updated on Jun 2, 2025
