Problems solved by technology
However, in the case of exceeding several times the rated speed of the motor, such as the DC traction motor of a mining level car, it is easy to overspeed when going downhill. Due to the low mechanical strength and poor high-speed resistance of the commutator of the DC motor, the DC motor The commutator was smashed, which caused damage to the stator, rotor, brush holder and other components, seriously affecting the production efficiency of coal mining enterprises

Disclosed is a DC motor commutator. The DC motor commutator comprises commutator sheets, a mica sheet, at least two alloy rings and an axle sleeve. The commutator sheets are provided with fixation holes whose number is corresponding to the number of the alloy rings, the surfaces of the alloy rings are provided with insulation layers, each alloy ring correspondingly passes through one fixation hole in one commutator sheet so as to enable the commutator sheet to be relatively fixed to the alloy rings, the mica sheet is provided with clamping grooves whose number is corresponding to the number of the alloy rings, the mica sheet is arranged between adjacent two commutator sheets, and each clamping groove of the mica sheet is clamped on the corresponding alloy rings. According to the invention, the alloy rings provided with the commutator sheets and the mica sheet sleeve the outer surface of the axle sleeve, gaps between the alloy rings which are provided with the commutator sheets and the mica sheet and the axle sleeve are filled up with insulation resins so as to relatively fix the alloy rings provided with the commutator sheets and the mica sheet to the axle sleeve, and the inner surface of the axle sleeve is provided with a key groove relatively fixed to the rotation shaft of a motor rotor. The invention also provides a manufacture method of a DC motor commutator, and a DC motor.
Description
[0001] Technical field: [0002] The invention relates to the technical field of DC motors, in particular to a DC motor commutator, a manufacturing method and a DC motor. [0003] Background technique: [0004] The commutator is a part of the DC motor in order to allow the motor to continue to rotate. When the coil passes through the current, under the action of the magnetic field, it rotates through the attraction and repulsion force. When it turns to balance with the magnet, the contact piece on the corresponding commutator of the originally electrified coil is separated from the brush, and The brushes are connected to the contacts corresponding to the set of coils that generate the driving force, and this repeats continuously, and the DC motor turns. [0005] Whether the existing DC motor commutator is a compression plastic series or an arched series, each piece of commutator is fixed on the ring by hooking. The motor fully meets the requirements. However, in the case of ...
