Description
Technical field
The utility model relates to a kind of motor skeletons.
Background technique
In motor concentrating winding group, skeleton be used to support winding coiling, while also by between winding and stator core into
Row insulation.In order to promote the power density of motor, need as far as possible around some more copper wire (promoting copper factor) in narrow space, but
Thus the place such as pole shoe end that skeleton is also compared concentration by bigger extruding force, especially part stress is connect with winding section turns
At angle, because local pressure is concentrated at this, it is easy to happen fracture.
The limitation of present material technology and spatial design, the selection for only relying on material not can guarantee product structure intensity, and
Cost is also very high.Meanwhile because skeleton is moulding, conventional injection molding technique waveform due to the influences such as technological parameter, environment
Greatly, the skeleton worked it out often has the defects of unfilled corner, burn, split, and leads to motor pressure resistance defective insulation, under the safety of product
Drop, it could even be possible to because winding and stator core contact short circuit cause motor to burn.
Utility model content
The utility model be intended to provide a kind of structure it is simple, it is easy to make, framework collapse situation can be improved and improve motor
The motor skeleton of reliability.
It is realized by following scheme:
A kind of motor skeleton, including yoke portion end and pole shoe end, yoke portion end are connected with pole shoe end by winding section
Integral and yoke portion end, pole shoe end, winding section one end end face the end face coordinate contact surface of stator core, institute is concordantly collectively formed
The other end for stating winding section is winding mounting surface and winding mounting surface lower than yoke portion end, the other end at pole shoe end, it is described around
Group mounting surface is tilted a certain angle from pole shoe end to yoke portion end towards close to the end face coordinate contact surface direction of stator core, it is described around
The two sides for holding a neat end face level with both hands with yoke portion in line portion, which are respectively perpendicular, is provided with rib.
According to physical mechanics it is found that pole shoe end is concentrated the most with stress at the connecting corner of winding section, in conjunction with actual conditions, pole
It is also easiest to stress at boots end and winding section connecting corner and is broken.Winding mounting surface is arranged to from pole shoe end to end court, yoke portion
Close to stator core the inclined inclined surface in end face coordinate contact surface direction, it is assumed that pole shoe end with it is original at the connecting corner of winding section
Stress is F, and the angle formed between winding mounting surface and the end face coordinate contact surface of stator core is θ, pole shoe end and winding section
Stress becomes F × cos (θ) at connecting corner, is less than original stress F, it is seen then that winding mounting surface is arranged to inclined surface, can be had
Effect reduces pole shoe end, and institute is by stress at the connecting corner of winding section, so as to improve framework collapse situation.In addition, winding mounting surface with
The angle theta formed between the end face coordinate contact surface of stator core too small should not also should not be too large, if too small, the stress of reduction has
Limit, improvement is unobvious, if excessive, will affect winding coiling arrangement, copper factor can be low.The winding mounting surface and stator iron
The angle formed between the end face coordinate contact surface of core is preferably 3~10 °.
Further, an end face concordant with winding section at yoke portion end is located at the close inward flange of winding section two sides
The first card slot is offered on position respectively, an end face concordant with winding section at the pole shoe end is located at the close of winding section two sides
The second card slot is offered on the position of inward flange respectively, is glued with slot insulating paper and slot insulation on the one side inwardly of the rib
The both ends of paper, which respectively correspond, vertical mating is inserted into the first card slot, in the second card slot.The setting of first card slot, the second card slot, can
Play the role of fixed slot insulating paper.First card slot, the second card slot width are matched with slot insulating paper thickness, the first card slot,
The shape of two draw-in groove can be designed according to process conditions, slot insulating paper shape with slot insulating paper sufficiently with the first card slot, second
Card slot matches to be designed.
Further, first card slot, the second card slot side outwardly be respectively arranged with raised block, the rib
Both ends are connected together with corresponding raised block respectively.
The motor skeleton of the utility model, structure is simple, easy to make, by the way that the winding mounting surface of winding section to be arranged
At inclined surface, pole shoe end is effectively reduced with institute at the connecting corner of winding section by stress, hence it is evident that improve the bad feelings of framework collapse
Condition；By the setting of slot insulating paper, motor can be prevented because pressure resistance is absolutely caused by breakage in skeleton product itself or manufacturing process
Edge is bad, plays double insulating effects, improves the product reliability of motor.
