Problems solved by technology

[0003] However, due to the temperature resistance of bakelite powder and the limitations of the molding process, the current structure often cannot guarantee the consistency of quality. In commutators with heavy copper bars or large outer diameters, the centrifugal force is different from that of the commutator. The mass and the outer diameter are proportional. The larger the mass and the outer diameter, the greater the centrifugal force, and the mechanical strength of the bakelite powder cannot meet the requirements of higher performance motors. The surface difference of the copper bar surface will exceed the standard when it is running at high speed. requirements, causing motor sparks and thus affecting the life of the motor

Embodiment 1

[0022] Figure 1-3 As shown, a new commutator includes a ceramic body 3 and a commutator segment 1 arranged on the periphery of the body. The commutator segment includes a working section 11 located on the outer surface of the body and a fixed foot 12 extending into the body. A groove 4 protruding into the main body is provided between the working section 11 and the fixed foot 12 of the ceramic body, and the fixed foot 12 of the commutator segment 1 is fixed in the groove 4 of the ceramic body by heat-resistant glue 2 .

Embodiment 2

[0024] Figure 4-5 As shown, the copper ring 6 is welded and fixed on the periphery of the ceramic ring 5 with solder, and then the copper ring 6 is cut with a milling cutter to form commutator segments 1 arranged at equal intervals.

Abstract

The invention discloses a novel commutator which comprises a main body and commutator bars arranged at the periphery of the main body, wherein the main body is made of ceramic material. The commutator can reduce a section difference between the bars during operation, and the mechanical properties of the high-power commutator with larger radius can be improved, so that the service life of the commutator is prolonged.

Description

technical field [0001] The invention relates to a commutator with a new structure. Background technique [0002] The commutator is the main part of the motor. At present, the commutator is mainly composed of a bakelite main body and copper bar commutation pieces arranged on the periphery of the bakelite main body. [0003] However, due to the temperature resistance of bakelite powder and the limitations of the molding process, the current structure often cannot guarantee the consistency of quality. In commutators with heavy copper bars or large outer diameters, the centrifugal force is different from that of the commutator. The mass and the outer diameter are proportional. The larger the mass and the outer diameter, the greater the centrifugal force, and the mechanical strength of the bakelite powder cannot meet the requirements of higher performance motors. The surface level difference of the copper bar surface will exceed the standard when it is running at high speed. req...
