Question
A 15 kW, 440 V, 4 Pole, 50 Hz, 3 Phase induction motor is built with a stator bore $0.25 \text{ m}$ and a core length of $0.16 \text{ m}$. The specific electrical loading is $23000 \text{ ampere conductors per metre}$. Using this data of machine, determine the core dimensions, number of stator slots and number of stator conductors for a $11 \text{ kW}$ $460 \text{ V}$, $6 \text{ pole}$, $50 \text{ Hz}$ motor. Assume a full load efficiency of $84 \text{ percent}$ and a power factor of $0.82$ for each machine. The winding factor is $0.955$.
