Description
Technical field
The present invention relates to technical field of driving, more particularly to a kind of stator and motor.
Background technology
Motor includes mainly stator and rotor, and when work, stator generates rotating excitation field, and rotor is in rotating excitation field by magnetic force
Wire cutting and generate electric current.
Conventionally employed stator includes mainly two kinds of structures：
1, chain structure is spelled, multiple iron core units are connected at chain form, when the stator that multiple iron core units are spliced into whole circle
It after iron core, is welded and fixed between multiple iron core units, iron core unit uneven heating, therefore iron core can be caused by the way of welding
Unit is easily deformed, and is occurred so as to cause the bad situation of the inner circle circularity of entire stator core；
2, lamination structure includes the multiple laminations and two end plates of whole circle setting, and in assembling, multiple laminations are mutual
It is superimposed together, and the integral retaining after overlapping passes through after then being compressed by hydraulic press and circumferentially between two end plates
End plate and multiple laminations are welded and fixed by multiple pads, and since hydraulic press can be withdrawn after welding, such lamination is folded
Closing height can rebound, and close to the position of pad, rebound is smaller, and the position rebound far from pad is larger, whole to cause
The verticality of a stator faces and inner circle is bad, since the stator faces are mounting surface, if stator faces are vertical with inner circle
Spend it is bad, then can cause stator installation tilt, cause stator deformability.
Invention content
