As a kind of preferred version, described stator core is provided with 4 through holes, and each through hole evenly is located at effective outer diameter zone each middle side edge in addition of stator, is respectively equipped with the key steel that prevents that stator deformability from using in each through hole.According to the actual size of motor, the number of each through hole and correspondent button steel also can be provided with as required.
Described punching is that thickness is the silicon steel sheet of 0.5mm or 0.35mm.
The utility model is a kind of to be used for the manufacture method that above-mentioned motor prevents the device of stator deformability, may further comprise the steps:
(1) carry out punching in each punching of forming stator core, form at least two through holes that pass punching respectively, each through hole is evenly distributed on beyond effective outer diameter zone of stator;
(2) each punching that will form stator core laminate neat after, adopt to laminate frock mechanism each punching is clamped, form one to welding, make each punching that overlaps together around each punching then, be stator core;
(3) squeeze into corresponding key steel respectively in each through hole, adopt the fit system of matched in clearance between key steel and the through hole, the length of key steel is than the little 3～5mm of length of stator;
(4) remove clamp that punching uses laminate frock mechanism, motor prevents that the device manufacturing of stator deformability from finishing.
In the above-mentioned manufacture method, the described frock mechanism that laminates is that stator core laminates frock.
Described to the employing of the welding around punching argon arc welding.
In manufacture process, each through hole must be located at beyond effective outer diameter zone of stator, in order to avoid it is close to increase stator yoke portion magnetic, thereby influences the normal use of motor; Simultaneously, key steel thickness can not be thin excessively, if thin excessively, then to stator core intensity to improve use little; In the whole manufacturing process, need to keep laminating frock mechanism and clamp each punching that overlaps together, in order to avoid punching flicks during to the stator punching.
The utility model has following advantageous effect with respect to prior art:
(1) add this device on the stator of middle and small motor, to after welding around the stator, load key steel again can effectively improve the intensity of stator, prevents stator deformability; After adding this device on the stator, when guaranteeing stator intensity, can save electric machine stand, make its outward appearance better, structure is also simpler; This device can well be applied to the middle and small motor field.
(2) manufacture method of this device is simple, needs only punching and load key steel on original stator structure, and its manufacture process is simple, and does not influence the original structure of motor.
