Description
Technical Field
The utility model relates to a motor element, especially a motor stator slot insulating part.
Background
A winding stator of a general motor is generally composed of a winding lead-out wire, a stator core, a stator winding, slot insulation paper, a coil, a slot wedge, layer insulation paper, and the like. When the motor is assembled, each motor is required to be provided with the same amount of slot insulation paper according to different stator slot numbers. Before embedding the coil, the slot insulating paper is sequentially put into the stator core slot, and then the wire embedding operation is carried out. Whether the slot insulation paper is manually inserted or mechanically operated, the slot insulation paper with the same length and width needs to be cut in advance according to the size of the slot, and then the slot is inserted into the slot one by one, so that the time and the labor are consumed, and the production efficiency is low. Meanwhile, since the slot insulation paper is in a straight-bar cylindrical shape, local micro deformation and displacement can be generated in the processes of workpiece carrying, assembly and the like, and the stator winding is easy to have short-circuit faults between the notches of the two end faces of the iron core and the coils.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a motor stator slot insulating part to simplify motor stator's insulation system, improve production efficiency, prevent that the motor from taking place short-circuit fault.
In order to solve the technical problem, the utility model discloses a motor stator slot insulating part, including being used for fixing the insulating disc at the stator core tip, insulating disc side integrated into one piece has a plurality of axial extensions, is used for imbedding the insulating strip of stator core recess, and this insulating strip is circumference evenly distributed, the length of insulating strip is stator core's length half, forms the insulating cover that supplies the embedding of stator core wrapping post between the insulating strip.
The insulating strip top is the arc, and the insulating strip width narrows down from outer to interior gradually for the insulating strip better cooperates with stator core recess.
The end part in the insulating sleeve is provided with a positioning cavity correspondingly clamped with the winding post of the stator core, so that the head part of the winding post of the core can be clamped into the positioning cavity, and the accurate installation and positioning of the motor stator slot insulating part are realized.
The utility model has the advantages that: in the motor stator slot insulator structure, when a motor stator is embedded with a wire, two motor stator slot insulators are relatively inserted into a stator core and are spliced together, an insulating strip is embedded into a stator core groove, a stator core winding post is embedded into an insulating sleeve, the stator core achieves a good insulating effect, the insulating structure of the motor stator is greatly simplified, the production efficiency is improved, the motor is prevented from short-circuit faults, two end faces of the stator core are covered by insulating discs, and faults caused by end breakdown of the stator core with a winding are reduced.
