Abstract
The utility model belongs to the field of motors and particularly relates to a commutator for a motor. The commutator comprises mica plates and compression molding materials, wherein each mica plate is arranged between every two adjacent T-shaped copper bars; the T-shaped copper bars and the mica plates are inserted into reversed T-shaped slots of the compression molding materials; and the compression molding materials are internally provided with reinforced loops. According to the utility model, with the adoption of the reinforced loops, the mechanical strength of the commutator is increased; the commutator has a higher rotation speed; and the commutator has small deformation when operating at a high speed.
Description
Technical field
The utility model belongs to electric motors, specifically is that a kind of motor is used commutator.
Background technology
Commutator is in order to let motor continue parts that rotate on the AC permanent magnet series-wound motor.On the structure, it is round that commutator is that several contact chips surround, and connects epitrochanterian each contact respectively, and two electrodes that the outside connects are called brush and contact with it, simultaneously wherein two of contact only.Principle is that after coil passed through electric current, meeting was under the effect of permanent magnet; Through attracting and the repulsive force rotation; When it forwarded to the magnet balance, the contact that was leading to originally on the electric more corresponding commutator of line was just separated with brush, and brush is connected on the contact that meets that group coil correspondence that produces motive force; The repeat of not stopping like this, DC motor has just been turned over.If there is not the effect of commutator, it is just stuck less than half-turn that motor can only change, and can only be used as electric brake.General commutator mechanical strength after the motor running heats up is not enough, causes damage, and just motor can't be worked.
Summary of the invention
The problem that will solve of the utility model provides a kind of mechanical strength height, can obtain more high-revolving commutator.
The utility model provides following technical scheme:
Motor is used commutator, and it comprises T shape copper bar, mica sheet and compression molding material, is equipped with mica sheet between adjacent two T shape copper bars, and T shape copper bar and mica sheet insert in the inverted T-shaped slot of compression molding material,, be provided with in the compression molding material and strengthen hoop.
Through strengthening the mechanical strength that has increased commutator that is provided with of hoop, make it obtain higher rotating speed, running up down, the commutator distortion is little; Simultaneously, compression molding material adopt electric ink powder as materials processing get up more convenient, heatproof is high, intensity good.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the schematic side view of Fig. 1.
Embodiment
As shown in Figure 1, motor is used commutator, and it comprises T shape copper bar 1, mica sheet 2 and compression molding material 3; Be equipped with mica sheet between adjacent two T shape copper bars; T shape copper bar and mica sheet insert in the inverted T-shaped slot of compression molding material, and compression molding material is provided with copper bar and fixedly moulding of mica sheet and strengthens hoop 4 in the compression molding material; Fixedly after the moulding, the mechanical strength of commutator will be greatly improved at compression molding material.
