Abstract
The utility model relates to a commutation structure of a disc type permanent magnet motor, which comprises an electric brush and an armature winding, wherein the conductor part of the armature winding is formed by the lamination and serial connection of formed coils; and the electric brush has a positive electrode and a negative electrode, is arranged in the centre of the armature winding and contacts with the coil edges of the formed coils. The commutation structure in the utility model changes the structure of the traditional armature winding; current commutation is carried out by utilizing the formed coils of the armature winding skillfully to contact with the electric brush; and the structure and the shape of the motor are simplified and the overall dimension and weight of the complete machine are reduced, so that the commutation structure has the advantages of small dimension, compact structure, cost conservation and the like.
Description
Technical field
The utility model relates to a kind of commutating structure of motor, particularly relates to a kind of commutating structure of desk permanent-magnet motor.
Background technology
At present, existing desk permanent-magnet motor adopts commutator to realize the commutation of electric current usually, makes the overall structure and complex-shapedization of motor owing to be provided with commutator in permanent magnet motor, and has increased weight, size and the cost of motor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of commutating structure of desk permanent-magnet motor, simplifies the overall structure and the shape of motor.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of commutating structure of desk permanent-magnet motor is provided, comprises brush and armature winding, the conductor part of described armature winding is laminated by formed coil and is in series; Described brush is divided into positive pole and negative pole, is arranged on the central authorities of described armature winding, and contacts with the coil side of described formed coil.
Described brush is at least two pairs.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model has changed traditional armature winding structure, utilizes direct the contact with brush of formed coil of armature winding to carry out the electric current commutation dexterously.Compare the common permanent magnet direct current motor of unidimensional specification, directly reduce material cost, simplified the structure and the shape of motor again, reduce the overall dimension and the weight of complete machine, so have advantages such as size is little, compact conformation, saving cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Execution mode of the present utility model relates to a kind of commutating structure of desk permanent-magnet motor, as depicted in figs. 1 and 2, comprises brush and armature winding, and the conductor part of described armature winding is laminated by formed coil and is in series; Described brush is divided into positive pole and negative pole, is arranged on the central authorities of described armature winding, and contacts with the coil side of described formed coil.
Operation principle of the present utility model: electric current feeds from the positive terminal of brush 1, flows directly into the coil side of the formed coil of armature winding 2 correspondences of contact with it then, and behind several formed coils through series connection, the direct again negative pole end from brush 1 flows out.When operate as normal, armature winding 2 is owing to the effect that is subjected to electromagnetic force is rotated, after armature winding 2 turns over certain angle, the coil side of original formed coil that contacts with brush 1 has broken away from brush 1, but the coil side of the formed coil that it is adjacent will inevitably be replaced the coil side of original formed coil, thereby contact with brush 1, so circulation promptly is the commutation process of whole desk permanent-magnet DC motor.Need to prove, in the utility model, can also be provided with in the central authorities of armature winding many to brush, to satisfy the demand of different motor.
Be not difficult to find that the utility model has changed traditional armature winding structure, utilize dexterously direct the contact with brush of formed coil of armature winding to carry out the electric current commutation. Compare the common permanent magnet direct current motor of unidimensional specification, directly reduce material cost, simplified again structure and the shape of motor, reduce appearance and size and the weight of complete machine, so have the advantages such as size is little, compact conformation, saving cost.
