Title:
BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JPH0823654
Kind Code:
A
Abstract:

PURPOSE: To prevent the formation of loosened parts in the terminal sections of coils wound around the teeth of a core by arranging the connection lands of a motor board at intervals which are equal to the quotient of the division of 360°C by the number of teeth or larger on the winding direction side from the centers of the teeth.

CONSTITUTION: Connection lands 10, 11, 12 are arranged at the end sections of coils on a motor board 9 and the terminal sections 8a, 8b, and 8c of U-, V-, and W-phase coils are respectively soldered to the lands 10, 11, and 12. The interval between each land 10, 11, and 12 is made egual to the quotient of the division of 360°C by the numder (12) of the coils. In addition, the lands 10, 11, and 12 are deviated from the centers of cores 13, 14, and 15 in the winding direction side of windings by an angle θ. Therefore, the coils are not unwound and the terminal sections 8a, 8b, and of the coils wound around the cores 13, 14, and 15 are wound around already wound coils. As a result, the terminal sections 8a, 8b, and 8c can be easily connected to the lands 10, 11, and 12 on the board 9.
