Title:
POLE CHANGE 3-PHASE ARMATURE COIL
Document Type and Number:
Japanese Patent JPS58136254
Kind Code:
A
Abstract:
PURPOSE:To enhance the space factor in a coil grooves, to improve the characteristics and to improve the utility rate of coils by forming high speed poles of real poles, and superposing and one or more of false poles to balance the voltage vectors of the respective phase coils. CONSTITUTION:Coils of windings of respective phases, e.g., in case of the phase U, #1-#11, #3-#13, #5-#15 are used as U-phase group VA, #10-#2, #12-#4, #14-#6, are as B group UB, and the groups A, B are disposed at every other slots in such a manner that the coils of the group B are disposed among the coils of the group A. The coils of the group A are connected in series to become in the same winding direction, the group B are connected in series in reverse direction to the group A, these two coil group UA, UB are connected, the both ends are U1, X, and the intermediate point is as U2. In the phases V and W, the coils are similarly disposed. In this manner, the utility rate of the coil can be improved, and the characteristics can be improved.
