ELEN 3441 – Fundamentals of Power Engineering Spring 2011 Page | 1 Homework 5 – Solution 4.1. (25 pt.) The equation relating the speed of magnetic field rotation to the number of poles and electrical frequency is: 120 e m f n P = The resulting table is: 2 4 6 8 10 12 14 0 500 1000 1500 2000 2500 3000 Number of poles of an AC machine Motor speed, rpm 4.2. (25 pt.) a) The frequency of the voltage produced in this winding is 1800 4 60 120 120 m e nP f Hz = == b) There are 12 slots on this stator, with 40 turns of wire per slot. The voltage in the coils in one phase (same as terminal voltage for delta) is:
