Reference Answer
### (a) Various Losses in a Squirrel Cage Induction Motor on Load
The total losses in a squirrel cage induction motor are the difference between the electrical power input to the stator and the mechanical power output at the shaft. These losses are converted into heat, which must be dissipated by the motor's cooling system. The losses can be broadly classified as follows:
**1. Stator Losses**
These losses occur in the stationary part of the motor.
