Background technology:
At present, induction machine adopts winding to produce rotating magnetic field pulling rotor usually and rotates, for guaranteeing the steady output of power of motor, the magnetic field that winding produces should evenly distribute in stator core inside in the cycle, therefore the profile of motor stator core optimum is circular, the utilance of existing motor stator punching when considering to improve the silicon steel sheet stamping-out, save cost, tend to motor stator punching is cut edge, but stator punching is cut edge and will be caused magnetic field circle distribution direction area not wait, magnetic field is inhomogeneous, thereby makes the noise of motor, vibration, torque pulsation increases, and efficient reduces.
Summary of the invention:
The purpose of this utility model provides a kind of stator core construction, alternately laminates by stator punching, makes the Distribution of Magnetic Field of motor even, improves efficiency of motor, noise, and performance, torque pulsation, performances such as temperature rise, thus reduce motor cost.
The purpose of this utility model is achieved by following technical proposals.
A kind of stator core construction, comprise by some punching bodies and being overrided to form from top to down, each punching body comprises yoke portion, tooth portion and centre bore, form teeth groove between the adjacent teeth portion, have some side cuts on each punching body, be arranged in the side cut alignment on the punching body of odd positions, be arranged in the side cut alignment on the punching body of even number position, be arranged in side cut and the side cut on the punching body that is arranged in the even number position on the punching body of the odd positions certain angle a that staggers.
Above-mentioned described angle a is 45 angles of spending or crossing over several teeth groove.
Excessive between above-mentioned described two adjacent side cuts by circular arc.
The quantity of above-mentioned described some side cuts is 4 and adjacent two and cuts edge vertical mutually.
Positioning recess is set in the middle of the above-mentioned described side cut, and between the two adjacent recesses, in the yoke portion installing hole is set, the angle of recess and installing hole is 45 to spend.
Above-mentioned described some punching shapes are identical.
The utility model compared with prior art, has following effect: 1) be arranged in the side cut alignment on the punching body of odd positions, be arranged in the side cut alignment on the punching body of even number position, be arranged in side cut and the side cut on the punching body that is arranged in the even number position on the punching body of the odd positions certain angle a that staggers, the Distribution of Magnetic Field of motor is even, improve efficiency of motor, noise, performance, torque pulsation, performances such as temperature rise, thus motor cost reduced; 2) angle a is 45 degree or several line embedding groove angles, makes the stator punching neat appearance; 3) quantity of some side cuts is 4 and adjacent two and cuts edge vertically mutually, in the middle of cutting edge positioning recess is set, and between the two adjacent recesses, in the yoke portion installing hole is set, the angle of recess and installing hole is 45 to spend, and is easy for installation, enhances productivity.
