Problems solved by technology

[0002] In the commutator used on the existing motor, the cross section of the commutator piece is I-shaped, and the longitudinal surface is double dovetail groove shape. After the commutator is integrally formed, the insulation space between the commutator pieces is small, and the insulation The capacity is affected, and the material consumption of the commutator is relatively large (generally, the material of the commutator is made of copper alloy), and the material cost is increased. The working state of the commutator is high-speed operation, and the overweight of the commutator will increase the centrifugal force Increase the dynamic deformation of the commutator and reduce the performance

Embodiment Construction

[0013] The accompanying drawings show the embodiment of the present invention and its structure, and the relevant details of the embodiment will be further described below in conjunction with the accompanying drawings. Firstly, the commutator piece is drawn with known technology according to specific specifications to produce a cross-section such as Figure 4 The commutator piece strip shown in the figure, and then the strip is processed by stamping method such as image 3 As shown in the figure, the commutator with two trapezoidal through-holes is then formed by arranging the pieces, inserting the mica pieces, pressing the whole with fillers, turning, milling, stamping and other processes to complete the whole commutator.

Abstract

The present invention relates to a shape improvement of the commutating segment in the commutator, the invention comprises the whole body of the commutator, the cross section of the commutating segment is designed to shapes of T-shape or approximate T-shape and the like, also can be other shape, and the invention is characterized in that the longitudinal surface of the commutating segment is arranged with a quadrangular through hole. Comparing with the present technique the invention has the advantages of reducing the consumed material by the commutating piece, reducing the cost, more reasonable combining between the commutating segment and the filler, increasing the strength and insulating property of the whole commutator.

Description

technical field [0001] The present invention relates to the improvement of the shape of commutator segments in commutators used on electric machines. Background technique [0002] In the commutator used on the existing motor, the cross section of the commutator piece is I-shaped, and the longitudinal surface is double dovetail groove shape. After the commutator is integrally formed, the insulation space between the commutator pieces is small, and the insulation The capacity is affected, and the material consumption of the commutator is relatively large (generally, the material of the commutator is made of copper alloy), and the material cost is increased. The working state of the commutator is high-speed operation, and the overweight of the commutator will increase the centrifugal force The dynamic deformation of the commutator increases and the performance decreases. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention ai...
