1.	What is the formula of the end ring current?(a) end ring current = number of rotor slots * bar current * 3.14 * number of poles(b) end ring current = number of rotor slots * bar current * 3.14 / number of poles(c) end ring current = number of rotor slots / bar current * 3.14 * number of poles(d) end ring current = number of rotor slots * bar current / 3.14 * number of polesI got this question in an interview for job.My doubt stems from Design of Rotor in division Design of Single Phase Induction Motor of Design of Electrical Machines
Answer» The CORRECT ANSWER is (d) end ring current = number of rotor slots * bar current / 3.14 * number of poles To EXPLAIN: The number of rotor slots and the bar current along with the number of poles is calculated. On SUBSTITUTION it GIVES the end ring current value.
