Abstract

The utility model relates to an automobile starting motor comprising a stator and a rotor. The rotor comprises an armature core, an armature shaft penetrating the armature core, an armature winding wound on the armature core and a commutator connected with the armature winding, the commutator comprises a contact piece in a circle, the diameter of the commutator is equal to that of the armature core, the contact piece extends along the axial external diameter of an armature, and a contact surface of the contact piece and an electric brush is arranged on the end face of the commutator. By improvement on the structure of the commutator, contact area of the electric brush and the commutator can be increased so as to decrease contact current, and motor performance is improved.

Description

A kind of automobile starting motor motor
Technical field
The utility model relates to a kind of automobile starting motor.
Background technology
Automobile starting motor includes motor, transmission mechanism and electromagnetic switch, the commutator diameter of rotor is less than armature diameter, the contact-making surface of itself and brush is arranged on outer peripheral face, brush is around commutator periphery, brush rubs with commutator all the time, and also can produce the bright erosion of electric spark in the moment of commutation, can reduce pick-up current etc. so increase the contact-making surface of the contact chip of commutator.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of automobile starting motor motor that can reduce pick-up current and reduce loss.
The technical scheme in the invention for solving the technical problem is:
A kind of automobile starting motor motor, comprise stator and rotor, described rotor comprises armature core, wears the armature shaft of armature core, is wrapped in the armature winding on armature core, and the commutator of connection armature winding, described commutator comprises the contact chip that surrounds circle, the diameter of described commutator is identical with the diameter of armature core, and described contact chip is extended by armature shaft outward radial, and the contact-making surface of contact chip and brush is arranged on the end face of commutator.
As preferably, the centre of the outer peripheral face of contact chip arranges groove, and described armature winding is connected in described groove.
As preferably, the outside tensioning of armature winding is provided with reinforcing ring.
As preferably, on the outer surface of armature core, be arranged with dynamic balancing groove.
As preferably, stator comprises casing and is fixed on the magnetic shoe in casing, at the bottom of one end envelope of described casing is provided with casing, at the bottom of casing, the mesopore wearing for armature shaft is offered at center, arranged outside brush carrier at the bottom of casing, on brush carrier, be slidably equipped with brush, the brush hole wearing for brush is also set at the bottom of casing.
The contact-making surface of the contact chip of commutator and brush is arranged on the end face of commutator, be different from cylinder commutator of the prior art, instead of in peripheral side, and the diameter of commutator is identical with armature core diameter, and brush is positioned at commutator one side contacts contact chip.Be different from prior art, brush is around contact chip outer ring rotating, and this kind of set-up mode, can increase contact-making surface area, thereby reduces pick-up current.The outside tensioning of armature winding has reinforcing ring, can prevent that winding is loose in rotary course.Due to the change of commutator structure, the structure of brush assembly of electric also will be carried out corresponding change, at the bottom of casing one end envelope is established casing, brush hole is set at the bottom of casing, and brush is slidably installed on brush carrier, and brush can connect commutator through the contact of brush hole.Be different from prior art, brush carrier is directly around in outside commutator.
The beneficial effects of the utility model are: the improvement of the structure of the utility model by commutator, thus the contact area that can increase brush and commutator reduces pick-up current, improves motor performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of automobile starting motor motor, comprise stator 7 and rotor 2, described rotor 2 comprises armature core 4, wears the armature shaft 1 of armature core, is wrapped in the armature winding 3 on armature core, and the commutator of connection armature winding, described commutator comprises the contact chip 6 that surrounds circle, the diameter of described commutator is identical with the diameter of armature core 4, described contact chip 6 is extended by armature shaft 1 outward radial, and the contact-making surface of contact chip 6 and brush is arranged on the end face of commutator.
The centre of the outer peripheral face of contact chip arranges groove 10, and described armature winding 3 is connected in described groove 10.The outside tensioning of armature winding is provided with reinforcing ring 5.On the outer surface of armature core, be arranged with dynamic balancing groove.
Stator 7 comprises casing and is fixed on the magnetic shoe in casing, one end envelope of described casing is provided with at the bottom of casing 8, and at the bottom of casing, the mesopore 9 wearing for armature shaft, the arranged outside brush carrier at the bottom of casing are offered in 8 centers, on brush carrier, be slidably equipped with brush, the brush hole wearing for brush is also set at the bottom of casing.
The contact chip of commutator 6 and the contact-making surface of brush are arranged on end face, are different from cylinder commutator of the prior art, instead of on circumferential surface, and the diameter of commutator is identical with armature core diameter, and brush is positioned at commutator one side contacts contact chip.Be different from prior art, brush is around contact chip outer ring rotating, and this kind of set-up mode, can increase contact-making surface area, thereby reduces pick-up current.The outside tensioning of armature winding has reinforcing ring, can prevent that winding is loose in rotary course.Due to the change of commutator structure, the structure of brush assembly of electric also will be carried out corresponding change, and casing one end envelope establishes at the bottom of casing 8, brush hole is set at the bottom of casing, and brush is slidably installed on brush carrier, and brush can connect commutator through the contact of brush hole.Be different from prior art, brush carrier is directly around in outside commutator.
The improvement of the structure of the utility model by commutator, thus the contact area that can increase brush and commutator reduces pick-up current, improves motor performance.
