Title:
MOTOR
Document Type and Number:
Japanese Patent JPH0739097
Kind Code:
A
Abstract:

PURPOSE: To reduce the length of the rotating shaft direction of a motor by a method wherein formed coils in one slot are connected to formed coils in other same phase slots with conducting members individually.

CONSTITUTION: Required number of formed coils 20 in one slot are connected to formed coils 20 in other same phase slots individually with conducting members 14 which are laminated in the rotating shaft direction of a motor with insulating layers in crossover coils 10 therebetween. Therefore, coils of the respective phases can be constructed without bundling a plurality of conductors. As a result, a variation in inductance values and fluctuation in torque can be reduced and the efficiency of the motor can be improved and, by utilizing the crossover coils 10, protruding lengths of coil ends in the rotating shaft direction can be reduced. With this constitution, the length of the rotating shaft direction of the motor can be reduced.
