Generator stator assembly

Technical Field

The utility model relates to a generator technical field especially relates to a generator stator assembly.

Background

The generator is a device for converting mechanical energy into electric energy, and is installed in a power plant, and the generator is divided into a direct current generator and an alternating current generator according to different power supplies. The generator is mainly composed of a stator, a rotor, an end cover, an electric brush, a base, a bearing and the like. The stator is composed of a base, a stator core, a coil winding and other structural members for fixing the parts.

The existing generator stator has poor heat dissipation effect, so that high temperature generated after the stator core is used for a period of time cannot be quickly dissipated, the service life of the stator can be prolonged, and the normal use of a generator is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a generator stator assembly to the not enough of prior art existence, concrete technical scheme as follows:

the utility model provides a generator stator assembly, includes stator core and locates the wire winding part of stator core inner wall, the wire winding part includes wrapping post and wire winding groove, stator core's inner wall ring-shaped distribution has a plurality of T font wrapping post, and forms the wire winding groove between two adjacent wrapping posts, the inside position that corresponds the wrapping post of stator core still fixes and is equipped with a plurality of radiating fin.

As an improvement of the technical scheme, the stator core is annular, and the interior of the stator core is hollow.

As an improvement of the above technical scheme, the heat dissipation fins are V-shaped, and sharp ends of the heat dissipation fins are fixedly connected with one side of the stator core close to the winding posts.

As an improvement of the technical scheme, the outer edge of the stator core is provided with heat dissipation holes corresponding to the positions of the openings of the heat dissipation fins, and filter screens are fixedly arranged in the heat dissipation holes.

As an improvement of the technical scheme, the outer surface of the stator core is subjected to electrophoresis treatment.

The utility model has the advantages that:

set up to hollow form through the inside with stator core, then the position that corresponds each wrapping post in stator core's inside all fixes and is equipped with V-arrangement radiating fin, and make the sharp-pointed one end of radiating fin towards the wrapping post, thereby can make stator core can transmit the high temperature that produces for radiating fin along the wrapping post in the in-process that uses, because V-arrangement radiating fin's the other end is the branching setting, so can increase the area of heat transfer, thereby can improve radiating effect, and utilize triangle-shaped to have stability, still make radiating fin provide the support for stator core, can improve the holistic intensity of stator core.
