Unformatted text preview: Initialize the c-phase is energized and the position is as indicated (point 1). Then the position is stepped to the b-phase. Circle the resulting stable equilibrium point and mark with a 2. Then the a-phase is excited. Circle and mark the stable equilibrium point with a 3. Continue in this fashion as the c-phase, b-phase, and finally a-phase are each excited a 2 nd time (thus the final point should be labeled 6). Problem 24 Machine Configuration It is desired that a stepper motor has a step length of 10 degrees. (This is for normal step operation). It is desired that the number of rotor teeth is less than 8 and than that the number of phases is less than 8. Sketch the configuration of such a machine. Your answer should be analogous to Fig 8.2-3 of Electromechanical Motion Devices ....
