Abstract

PURPOSE:To enable the change of the number of poles with a single coil in a relation of 2:3 by forming the first and the second coil groups made of the combination of the first coil, the second coil having reverse polarity to the first coil and the third coil having the same polarity as the first coil. CONSTITUTION:The second coil A2 is so disposed in the same as and adjacent groove to the first coil A1 in reverse polarity to the first coil A1 in the grooves 19 and 20, and the third coil A3 is disposed in the same groove as the second coil A2 in the same polarity as the first coil A1 in a groove 27. The coil group is formed of such the first to third coils, and is connected to terminals U1-W2. When operated with large number of poles, the terminals U1-W1 are connected to a power source, and when operated with small number of poles, the terminals U1-W1 are shortcircuited, and terminals U2-W2 are connected to a power source.
