What is the formula for the breadth of the ring slot?
(a) breadth of the ring slot = (number of turns in a band + 1)*diameter of band wire – 2*constant
(b) breadth of the ring slot = (number of turns in a band + 1)*diameter of band wire + 2*constant
(c) breadth of the ring slot = (number of turns in a band + 1)*diameter of band wire * 2*constant
(d) breadth of the ring slot = (number of turns in a band + 1)*diameter of band wire / 2*constant
I got this question in an interview for internship.
My enquiry is from Bracing of Rotor Windings in section Aspects of Design of Mechanical Parts of Design of Electrical Machines
