Abstract

The utility model provides a motor which comprises a rotor arranged in a wire embedded stator, a front bearing, a rear bearing, a front end cover and a rear end cover. The front bearing and the rear bearing support the rotor. The front end cover and the rear end cover are respectively arranged at the outer parts of the front bearing and the rear bearing. The motor is characterized in that: a bracket is arranged on the wire embedded stator in a connecting manner; the bracket, the front end cover and the wire embedded stator form a plastic package body after injection molding; and the rear end cover is connected at the rear end part of the plastic package body in pressing and matching manners. After being formed into a whole through injection molding, the motor has the advantages of compact structure, high efficiency, low noise, mild vibration, good insulating performance, high protection grade and long service life. On the other hand, the motor realizes that plastics replace steel as raw materials of a shell of the motor; as plastic package DMC materials are cheaper than steel materials, the manufacturing cost of the motor is saved. As the motor is high in efficiency and mild in temperature rise, optimization design can be carried out on the motor and therefore the total manufacturing cost of the motor can be reduced by 3 to 5% or so; moreover, as the bracket is arranged on the motor, the installation of the motor is convenient.

Description

A kind of motor

Technical field

The utility model belongs to technical field of motors, is specifically related to a kind of support and integrated motor of shell plastic packaging of having.

Background technology

What at present, some motor production firms such as domestic many lampblack absorbers, indoor air conditioner cabinet used on lampblack absorber is steel, aluminum hull motor.Shortcomings such as what its adopted is the conventional motors manufacturing process, and motor can only reach the common electric machine technical merit on performance, and it exists, and noise is big, poor insulativity, degree of protection are low; And, since present stage the rising steadily of metal material, cause improving constantly of manufacturing cost.

The utility model content

At the problem that prior art exists, the purpose of this utility model is to design and provides that a kind of production cost is low, performance good and motor technology scheme easy for installation.

Described a kind of motor, comprise the rotor that is arranged in the rule stator, the fore bearing of support rotor, rear bearing, reach the front end housing and the rear end cap that are arranged at fore bearing, rear bearing outside respectively, it is characterized in that connecting on the described rule stator support is set, constitute plastic-sealed body after support, front end housing and the injection moulding of rule stator, rear end cap is press-fitted and connects the plastic-sealed body rearward end.

Described a kind of motor is characterized in that constituting plastic-sealed body after described support, front end housing and the injection moulding of rule stator, and front end housing is press-fitted and connects the plastic-sealed body leading section, and support is inserted to be embedded and placed the plastic-sealed body rearward end.

Described a kind of motor is characterized in that described support grafting is arranged in the iron core groove of rule stator.

Described a kind of motor is characterized in that on the described support fixing hole being set.

Described a kind of motor is characterized in that described support adopts ferrous material to constitute.

After above-mentioned a kind of motor has adopted the integrated through injection molding moulding, have that compact conformation, high efficiency, low noise, vibration are little, the advantage of good insulation preformance, degree of protection height, long service life; It has realized the motor housing raw material to mould Dai Gang on the other hand, and the DMC material price of plastic packaging is lower than the price of steel, the manufacturing cost of having saved motor; The efficiency of motor height, temperature rise is low, can be optimized design to motor, and total manufacturing cost of motor can descend about 3-5%; Support has been installed again on the motor, has been made things convenient for the installation of motor.

Embodiment

As shown in Figure 1, a kind of motor has comprised fore bearing 1, front end housing 2, rotor 3, rule stator 4, support 5, rear end cap 6 and rear bearing 7.The two ends of rotor 3 are by fore bearing 1, rear bearing

Front and back are arranged in rule stator 4 endoporus after supporting, and front end housing 2 is arranged on the outside of fore bearing 1, and rear end cap 6 is arranged on the outside of rear bearing 7; Support 5 is pegged graft and is arranged in the iron core groove of rule stator 4, also is provided with fixing hole on the support 5, and support 5 can adopt materials such as iron, stainless steel to make, and the installation of support 5 is convenient to install motor; Constituted plastic-sealed body after support 5, front end housing 2 and 4 injection mouldings of rule stator, rear end cap 6 is press-fitted and connects the plastic-sealed body rearward end, has so just formed motor, and this type of motor can be used for lampblack absorber, air-conditioner outdoor unit.

As figure

Shown in, can also adopt support 5, rear end cap 6 and rule stator 4 are injection molded into one formation plastic-sealed body, front end housing 2 is press-fitted and connects the plastic-sealed body leading section, and support 5 is inserted to be embedded and is placed the plastic-sealed body rearward end, i.e. the plastic-sealed body at the rear portion of rule stator.This type of motor can be used for cabinet air-conditioner.
