Problems solved by technology

[0002] In the existing commutator design, all the commutator segments and mica grooves are evenly divided, and the width of the commutator segments is the same. This processing method is relatively simple and convenient for quality inspection. However, due to the equal mica grooves, the assembly After becoming a motor, it is easy to generate periodic noise at a specific speed

Embodiment Construction

[0031] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0032] In order to achieve the purpose of the present invention, an unequal commutator includes: a sleeve 2; a commutation segment 1, a plurality of commutation segments 1 are annularly arranged on the circumferential surface of the sleeve 2, and adjacent commutation segments There are clearance grooves 3 between the segments 1, the clearance grooves 3 are parallel to the axis of the sleeve 2, the widths of the clearance grooves 3 are equal, and the widths of several commutator segments 1 are not equal to the same value.

[0033] The beneficial effect of adopting the above technical solution is that the design of the commutator divides the width and corresponding included angle of each commutator segment into several different values. This unequal-width design reduces sparks and noise during the operation of the commutator and improves the service life of th...

Abstract

The invention discloses an unequal divided commutator, comprising a sleeve; a plurality of reversing tabs are annularly arranged on the circumferential surface of the sleeve, a gap groove is arrangedbetween adjacent reversing tabs, the gap groove is parallel to the self-axis of the sleeve, the gap groove widths are equal, and the widths of the plurality of reversing tabs are not equal to the samevalue. The number of reversing tabs is twelve. There are three angles 28 degrees, 30 degrees and 32 degrees corresponding to the width of each commutating piece with the self-axis of the sleeve as the vertex. The number of corresponding included angles of 28 degrees in the commutating piece is equal to the number of corresponding included angles of 32 degrees. The invention reduces the spark andnoise in the rotating process of the commutator, and prolongs the service life of the motor. The periodic noise of the commutator during rotation is eliminated.

Description

technical field [0001] The invention relates to the field of motor accessories, in particular to an unequal commutator. Background technique [0002] In the existing commutator design, all the commutator segments and mica grooves are evenly divided, and the width of the commutator segments is the same. This processing method is relatively simple and convenient for quality inspection. However, due to the equal mica grooves, the assembly After becoming a motor, it is easy to generate periodic noise at a specific speed. Contents of the invention [0003] The problem to be solved by the present invention is to provide an unequal commutator, which can reduce sparks and noise during the commutator rotation and improve the service life of the motor. Periodic noise during commutator rotation is eliminated. [0004] In order to solve the above-mentioned problems, the present invention provides a kind of unequal commutator, in order to achieve the above-mentioned purpose, the tech...
