Abstract
The invention discloses a motor stator improvement structure, which comprises a stator assembly. The stator assembly consists of an iron core and a winding, wherein radial slots are uniformly distributed on an inner circular surface of the iron core; winding teeth are formed between two adjacent slots; and the winding is embedded in the slots and wound on the winding teeth. An insulating strip is arranged between the winding and an inner surface of each slot; and two ends of the insulating strip extend out of openings at two ends of the slot. An annular insulating piece is respectively arranged on two end faces of the iron core, is arranged along a ring surface of the end part of the iron core and tightly coats the insulating strip. Due to the arrangement of the annular insulating pieces at the two ends of the iron core, the notch insulating strength at two ends of the stator slots is improved, and the leakage flux and leakage reactance on the end part of the stator winding can also be reduced.
Description
Technical field
The present invention relates to a kind of improvement structure of motor stator.
Background technology
Present motor mainly is made up of stator and rotor, stator is provided with the stator winding that is formed by insulated wire line system, after finishing, the stator winding coiling again it is carried out shaping, for security consideration, not only in the shaping portion at stator winding two ends, carry out colligation with insulating paper, also need the insulating trip in the wire casing to be prolonged and stretch out the insulation that the wire casing port is used for winding and wire casing port, but insulation effect still is not good enough, and can't guarantees the notch insulation of stator slot two-port.
Summary of the invention
Problem to be solved by this invention just provides a kind of motor stator improvement structure, improves the integral insulation intensity of stator, makes the use of motor safer, stablizes.
For solving technique scheme, the present invention adopts following technical scheme: a kind of motor stator improvement structure, comprise field frame assembly, described field frame assembly is made of iron core and winding, the inner headed face of described iron core is evenly equipped with radial wire casing, form the coiling tooth between adjacent two wire casings, described winding is embedded in the wire casing and is around on the coiling tooth, be provided with insulating trip between described winding and the wire casing inner surface, the wire casing both ends open is extended at described insulating trip two ends, it is characterized in that: also be provided with the ring-type insulating part on the described iron core both ends of the surface, described ring-type insulating part is along the setting of core ends anchor ring and pack tightly described insulating trip.
Further, the edge of described iron core both ends of the surface is provided with axial raised annular rib, and described ring-type insulating part is inlaid between annular rib and the insulating trip.
Further, described ring-type insulating part is by the annular body of being close to the iron core end face and be located at the annular bound edge that is used to pack tightly described insulating trip on the annular body inner ring surface and constitute.
Further, described ring-type insulating part is made by electro-insulating rubber.
Beneficial effect of the present invention: by the setting of iron core two ends ring-type insulating part, improve the notch dielectric strength of stator slot two-port, can also reduce the leakage flux and the leakage reactance of stator winding end.
