Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Depend on Figure 1-2 It can be seen from the illustrated embodiment that this embodiment has a DC motor with concentrated windings, including a stator and a rotor. The stator includes permanent magnet stator poles fixed on the inner wall of the machine base, and also includes a brush B1 connected to the positive pole of the power supply and connected to the power supply. The brush B2 connected to the negative pole; the rotor includes an armature core radially arranged on the rotating shaft, each armature core is wound with an armature winding to form an armature, and a commutator coaxial with the rotating shaft is fixed at one end of the armature core, Each armature core corresponds to two arc-shaped commutator slices, and each commutator slice is fixed on the commutator; when the armature rotates, brush B1 and brush B2 respec...

Abstract

The invention discloses a DC motor with a concentrated winding. The DC motor comprises a stator and a rotor, wherein the stator comprises permanent-magnet stator magnetic poles, the permanent-magnet stator magnetic poles are fixed on an inner wall of a machine seat, the rotor comprises armature cores, the armature cores are arranged on a rotation shaft in a radial direction, each armature core is wound around an armature winding to form an armature, a commutator is fixed at one end of the armature core and is coaxial to the rotation shaft, commutator sheets on the commutator is twice of the armature core poles in number, when the armature rotates, a brush B1 and a brush B2 are sequentially in contact with each arc rectification sheet in a sliding way, and six permanent-magnet stator magnetic poles, seven armatures and fourteen commutator sheets are arranged. The DC motor with the concentrated winding has the advantages that an inherent contact bridge of the DC motor in the prior art does not exist, so that the structure becomes simple, and the risk of short circuit among windings is reduced.

Description

technical field [0001] The invention relates to the technical field of DC motors. Background technique [0002] In the existing motors with concentrated windings, there are generally contact bridges. For example, the stator of the motor has 4 poles, the rotor has 6 stages, the number of commutator pieces is 12, and there are 2 carbon brushes, which are distributed at 90 degrees at fixed positions. The winding method is that the beginning of the winding is connected to the commutator piece, and after one pole of the rotor is wound, it is connected to the other commutator piece of the commutator, and then another commutator piece is connected, and then wound on the other pole. Wire. In this way, a contact bridge connected by winding wires is formed between the two commutator pieces. These contact bridges are piled up on each other, which is easy to form a short circuit, and the winding is complicated. Contents of the invention [0003] The technical problem to be solved ...
