Abstract

The utility model relates to an electric motor, comprising a fan housing of the electric motor (1), a rotor (4) and a stator plate (2). The integrated electric motor is formed by the following processes that the single-chip stator plate (2) is laminated to be a stator core inserted line, after dipping lacquer, the stator core inserted line is formed into a whole stator (3), and then the whole stator (3) is assembled with the rotor (4) and the outer housing fan housing of the motor. The single-chip stator plate (2) is a quadrate thin section with the surface provided with a wind guide tank (8) and a location pin hole (10). The angles of the single-chip stator plate are provided with connecting slots (11) for mutual connection, and edges are provided with a connecting hole (9) for mutual connection. Adopting the above technical scheme, the heat dissipation performance is greatly increased, the temperature rise of the motor is obviously reduced, the performance of the motor is improved, the utilization rate of the material is improved, the cost is lowered, the assembly of the parts is reduced and the product quality is enhanced.

Description

A kind of motor

Technical field

The utility model relates to the direct current machine field, more specifically relates to a kind of motor.

Background technology

In the alternating current machine field, common field frame assembly structure has finished product stator and schemes such as cast iron (aluminium) support close-fitting, finished product stator and roll bending support close-fitting, its common ground is: independently finished product stator, two parts of support are arranged, by press-fit, mode such as hot jacket with its close-fitting together, the stator punching of this finished product stator mostly number for circular.Circular stator punching exists more leftover pieces in the course of processing, the motor radiating muscle that assembling is finished exposes, and exists in the transportation because of the flimsy shortcoming of colliding with; And stator, support parts material difference, heat-conductive characteristic there are differences, and causes the electric machine temperature rise height, influences motor properties.

The utility model content

Problem to be solved in the utility model provides a kind of motor, its objective is the reduction material consumption, promotes motor performance.

For solving the problems of the technologies described above, the technical solution of the utility model is: comprise motor fan housing, rotor, the stator punching edge is provided with wind guide tank and dowel hole, and by connecting lamination, the inboard stator coil that embeds constitutes the integrated support that comprises stator.

Stator and support unite two into one, and have saved support, have reduced material consumption, have reduced cost, have improved benefit.And the more original circular stator type of square structure is easily packed, is piled up and transports.

Described monolithic stator punching is a rectangular tab, and wind guide tank is symmetrical arranged along the angle, and four limits are provided with the connecting hole that is used to connect end cap.The circular stator punching course of processing exists more leftover pieces, and stock utilization is about 60%～70%, and square punching helps discharge, and leftover pieces significantly reduce, and stock utilization can reach more than 95%.

The angle of described stator punching is provided with the link slot that is used to weld lamination.

Described integrated support connects front end housing and rear end cap by connecting hole respectively, is positioned at the rear end cap inboard, is connected with the radiator fan blade along the axial direction of rotor.

Described motor fan housing is the square fan housing that adapts with integrated support.

This structure is that built-in ventilation slot has increased performance of ventilating with respect to outer fin, and the heat-conductive characteristic of same material is identical, compares with the motor of stator assembling with former support, temperature rise obviously descends, improved motor performance, the dowel hole that is provided with in the punching is used to adorn the usefulness of end cap location.

On the basis that guarantees the stator punching magnetic property, square punching is through behind the lamination, the connecting hole that is provided with by the link slot that on the angle, is provided with and four limits, weld or rivet, become a support, the incorporate stator core of stator, pass through rule, dipping lacquer, assembling again, become the motor of a square appearance.

Described motor fan housing is square or rectangle, adapts with out frame.The square motor fan housing that the motor outer cover that assembling is finished matches with it.

A kind of motor of the utility model adopts technique scheme, has both satisfied the magnetic conduction function of stator core, and built-in air duct radiation performance improves a lot, and electric machine temperature rise obviously descends, and has improved motor properties; In the circular stator punching processing, exist more leftover pieces, stock utilization is about 60%～70%, and square punching helps discharge, and leftover pieces significantly reduce, and stock utilization can reach more than 95%, has improved the utilance of material, has reduced cost; This structure is built-in air channel, and the square intensity height of outward appearance has overcome and exposed radiating ribs because of colliding with, transport flimsy shortcoming, and simultaneously, the more circular motor of square structure is easily packed, piled up and transports; Stator and support unite two into one, and need not increase support in addition, have reduced the assembling between the parts, have improved product quality.
