Problems solved by technology

[0002] In the traditional winding method for motors with six slots and four poles, the structure of the motor is six slots, four poles and six commutation segments, the coil inductance is relatively large, and the magnetic energy stored in the commutation coil is relatively high, such as figure 1 As shown, the No. 1 commutation piece coil is wound to the No. 1 winding slot, the No. 2 commutator segment is wound to the No. 2 winding slot, and so on. This traditional winding method can only be applied to small-power motors.

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] see first figure 2 As shown, the winding structure of the permanent magnet brushed motor for six slots and four poles of the present invention includes 6 winding grooves 11, 2 pairs of magnetic steel 12 and 6 commutator segments 14, the original one is replaced in the present invention The coils on the winding slots are sequentially wound on two winding slots 11: for example, on the No. 1 winding slot and the No. 4 winding slot, two coils 13 are formed, wherein the No. 1 wire slot and the No. 4 winding slot The geometric relative position of the magnetic steel 12 is the same, and they are all located under the N pole. Therefore, compared with the original structure winding method, the two coils 13 wound on the No. 1 wire slot and the No. The geometric relative position of the commutation coil 13 is also the same, and so on, s...

Abstract

The invention discloses a winding method and a structure for a six-groove quadrupole permanent magnet brush motor. A coil on a conventional winding groove is wounded on a plurality of winding grooves in sequence to form a plurality of coils, and compared with the conventional structure winding method, the coils are ensured to be in the same geometric relative positions with magnetic steels. The coil on one winding groove is separated into a plurality of coils, compared with the conventional structure winding method, the groups of coils are in the same geometric relative positions with the magnetic steels, so that the inductance of the coils can be enabled to be greatly lowered, the magnetic energy stored by a reversing coil can be greatly lowered, and the condition that the conventional winding method can only be enabled to utilize a low power motor is improved.

Description
