In case of induction motors, the ratio of core length to pole pitch for minimum cost is taken as

Question

RRB Paper · Accepted Answer

In case of induction motors, the ratio of core length to pole pitch for minimum cost is taken as 1.5 - 2. A higher core length to pole pitch ratio can result in better motor performance and efficiency, but it can also increase the cost of the motor due to the increased amount of iron core material required. Therefore, to minimize the cost of the motor while maintaining acceptable performance and efficiency, a ratio of 1.5 - 2 is often used in the design of induction motors. The specific design requirements and operating conditions of a particular motor may require a different ratio to be used.

In case of induction motors, the ratio of core length to pole pitch for minimum cost is taken as
