Abstract
The utility model discloses a novel motor stator punching, which comprises a punching body in the middle of which a central hole is formed, wherein wire embedding slots and teeth are formed in the inner side of the punching body; the wire embedding slots are communicated with the central hole and are distributed along the circumferential direction of the central hole; and the notch width L of the wire embedding slots ranges from 0.001mm to 1.299mm. The notch size of the wire embedding slots is reduced, so that the magnetic harmonic waves are reduced, the electromagnetic noise is reduced, the magnetizing current is reduced, and the cost performance of a motor is improved.
Description
Technical field:
The utility model relates to the novel stator punching of a kind of motor.
Background technology:
Along with the motor market competition is fierce day by day, increasingly high to the requirement of motor cost performance, stator punching is as the motor important component part; The line embedding groove notch magnitude relationship of stator punching is to each item indexs such as magnetic conductance harmonic wave, electromagnetic noise and magnetizing current of motor, and is closely bound up with the motor cost performance, and traditional stator punching line embedding groove notch is bigger; Cause stator magnetic conductance harmonic wave big; Electromagnetic noise is big, and magnetizing current is big, and the motor cost performance is low.
Summary of the invention:
The purpose of the utility model provides the novel stator punching of a kind of motor, through reducing line embedding groove notch size, to reduce the magnetic conductance harmonic wave, helps reducing electromagnetic noise, reduces magnetizing current simultaneously again, promotes the motor cost performance.
The purpose of the utility model is achieved through following technical proposals.
The novel stator punching of a kind of motor; The punching body of centre bore is set in the middle of comprising; Punching body inboard is provided with line embedding groove and tooth, and line embedding groove communicates with centre bore and circumferentially distributes along centre bore, and the scope of the slot opening L of line embedding groove is between 0.001mm to 1.299mm.
The scope of the slot opening L of above-mentioned described line embedding groove is between 0.2mm to 1.2mm.
The scope of the D outer diameter 1 of above-mentioned described punching is between 65mm to 160mm, and the scope of the inside diameter D 2 of centre bore is between 35mm to 92mm.
The utility model compared with prior art; Have following effect: 1) scope of the slot opening L of the utility model line embedding groove is between 0.001mm to 1.299mm; It to reduce the magnetic conductance harmonic wave, helps reducing electromagnetic noise through reducing line embedding groove notch size; Reduce simultaneously magnetizing current again, promote the motor cost performance.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A partial enlarged drawing of Fig. 1.
Embodiment:
Below through specific embodiment and combine accompanying drawing that the utility model is described in further detail.
As depicted in figs. 1 and 2; The utility model is the novel stator punching of a kind of motor; The punching body 1 of centre bore 3 is set in the middle of comprising; Punching body 1 inboard is provided with line embedding groove 2 and tooth 4, and line embedding groove 2 communicates with centre bore 3 and circumferentially distributes along centre bore 3, and the scope of the slot opening L of line embedding groove 2 is between 0.001mm to 1.299mm; The scope of the slot opening L of line embedding groove 2 is between 0.2mm to 1.2mm; The scope of the D outer diameter 1 of punching is between 65mm to 160mm, and the scope of the inside diameter D 2 of centre bore 3 is between 35mm to 92mm; Described line embedding groove 2 is round bottomed vessel or flat-bottom slot.
The utility model to reduce the magnetic conductance harmonic wave, helps reducing electromagnetic noise through reducing line embedding groove notch size, reduces magnetizing current simultaneously again, promotes the motor cost performance.
