How to Determine Speed for an Ac Induction Motor | 2000-09 ... Illustration of a six-pole stator. One way an hvacr service tech can determine that s/he is making good motor replacement decisions in the field is to understand the concept of motor speed so that the speed of one ac induction motor can be matched to another. At the same time, techs also need to become familiar with the concept of poles, since poles represent one key to a successful replacement. # of poles and # of slots, what does it mean? - RC Groups |…
How do just change in connections of stator winding convert 2 ... Now if we connect slot 1 and slot 10 then the direction in two consecutive coil of same phase i.e coil side in 6 and in 8 has opposite current and a pole is created but if we connect slot 6 with slot 10 and slot 1 with slot slot 8 then current in slot 6 and slot 8 are in same direction so no pole is created. 3 phase induction motors with poles not equal to 3x ...
