Abstract

PURPOSE:To carry out an armature coil of a single coil having 2:3 of polar ratio by forming respective phase coils of the first and the second coil groups made of the first coil group, the second coil group having reverse polarity to the first coil group and the third coil group having the same polarity as the first coil group. CONSTITUTION:The first coil group is composed of the first coil group A1, the second coil group A2 having reverse polarity to the first group and reverse polarity, and the third coil group A3 in the vicinity of the second coil group having the same polarity as the first coil group A1. Such first to sixth coil groups are connected to the respective terminals U1-W2. At this time the coil pitch is 94.4% at the high speed rotating side and 141.7% at the low speed rotating side. The terminals U1- W1 are connected to a three-phase power source at the low speed operating time, the terminal U1-W1 are shortcircuitted at the high speed operating time, and the terminals U2-W2 are connected to the three-phase power source.
