Embodiment Construction
[0030] The first object of the present invention is to provide an insulating bracket between stator slots. The structural design of the insulating bracket between stator slots can effectively solve the problem of potential safety hazards between two adjacent coils in the stator slot. A second object is to provide an electrical machine comprising the above stator slot insulation bracket.
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The invention discloses a motor and a stator slot insulation support thereof. The stator slot insulation support comprises a first plate and a second plate which are in fixed connection; one end of the first plate and the middle of the second plate are in fixed connection; the first plate can be arranged between two coil sides in a stator slot; and the second plate can be arranged between a coil in a stator slot and a magnetic pole. The insulation support can be inserted between two coils in a stator slot, i.e., in inserting, the first plate is inserted between the two coil sides in the stator slot, meanwhile the second plate is inserted between the coil in the stator slot and the magnetic pole, accordingly, the first plate isolates the two coils in the stator slot, and meanwhile the second plate isolates the coil and the magnetic pole. Sparking and circuit connection of the two coils can be effectively avoided so as to avoid potential safety hazards. In addition, a safe distance between the two coils is enough if the first plate can be arranged between the two coils, therefore the safe distance between the two coils is substantially reduced and the slot fill factor of the stator slot is increased.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a motor and an insulating bracket between slots of a stator thereof. Background technique [0002] The stator of the motor includes an annular body 01, a magnetic pole 03 and a coil 02, wherein a plurality of magnetic poles 03 are located inside the annular body 01 and distributed along the circumferential direction, and there is a gap between two adjacent magnetic poles 03 to form a stator slot, and each Coils are wound on each pole, and two coil sides are accommodated in each stator slot. [0003] At present, when the coil is wound, the winding nozzle is generally used to drive the enameled wire to shuttle back and forth between the stator slots to realize the winding of the coil. After the winding is completed, in order to ensure the safe distance between the two coil sides and prevent the cross-series current from being scratched between two adjacent coils, there is a large g...
