Description
Technical field
The utility model relates to technical field of motors, specifically, relates to a kind of stator core for motor, stator and has the motor of this stator core.
Background technology
Motor is widely used in the various electric equipments of industrial production and life, and prior motor has stator and rotor, and stator has stator core and is wrapped in coil on the stator core, and the outer injection moulding of stator forms the plastic packaging shell.Rotor has rotor core, and the middle part of rotor is equipped with armature spindle, armature spindle usually with the rotor interference fit, and rotate with the rotation of rotor, and armature spindle is for outside outputting power.
The manufacture method of existing stator core generally is directly with the circular punching of blank punching out, then punching is overrided to form.This kind method is that the blank that annular takies is square area because of whole punching, so the angle of permanent magnetic material position material all can't utilize between four leftover pieces, inner notch, rotor core and the stator cores, becomes waste material.Stock utilization is low, the cost height, and mould is comparatively complicated, and punching out efficient is low.Need special interior around the machine coiling, complex structure, equipment cost height, and " mouth " font winds the line, threading speed is low, efficient is not high.
Another manufacture method is similar to most of incision with full circle stator yoke portion, only stays the narrower thin bridging of excircle part to connect.Be " one " font during punching out, at last with its circumflexion.This scheme can reach the minimizing material cost, improves the purpose of winding efficiency.But significant disadvantages is arranged also.Because iron core connects by thin bridging, for " one " font need be through bending the conglobate operation of shaping together, thin bridge portion ruptures easily, can not bend repeatedly during punching out.Can be out of shape after the bending of bending place, need wash out the part material in the bending scope, cause splicing not hold together in order to avoid interfering appears in distortion place, cause leakage field to increase thereby the effective contact area of this part is diminished, motor performance descends.It is dead will to be connected the part weldering behind the circumflexion at last, or adopts the pressurize of pressurize frock, to the last always dresses up motor, and technology is loaded down with trivial details and need drop into welding equipment or pressurize frock, and efficient is low.
Also having a kind of manufacture method is that stator core is divided into several same segments, is designed to arc at joining place, can rotate to an angle relatively behind the snapping, flexibility is better, can adopt single iron core coiling also can link the back coiling.But because this type of pieces together chain iron core location amalgamation face in radial direction, can't be at the positive center of two iron core teeth portions as the arc joining place amalgamation face of then locating at the positive center of two iron core teeth portions, row around the time coil winding machine can occur interfering; As the amalgamation face of location then the arc joining place can't be at the positive center of two iron core teeth portions at the positive center of two iron core teeth portions, row around the time stator core become stepped can't be at same horizontal plane, the design difficulty of coil winding machine is bigger.
