Abstract
The utility model relates to a low-noise small and special motor with a plastic shell, belonging to a technical innovation for changing the shell material of the motor, reducing the noise of the motor, improving the insulating grades of the motor and improving the work efficiency. The material for the metal shell of the motor is changed into plastic, a stator iron core which is inlaid with a wire wrap by a mould is integrally infused by hot pressing with an end cover at one end, and accordingly, the shell of the motor is formed; an end cover on the other end is fixed on the plastic shell by a self-threading screw.
Description
The utility model is to belong to little small and special electric machine to change sheathing material, reduces noise and improves the class of insulation of motor and the technological transformation of enhancing productivity.
Before the utility model was not made, the sheathing material of little small and special electric machine all was to adopt sheet metal stretch or aluminium die casting metalworking to form, and using in place moist, seriously corroded has just had certain limitation, also will consider the safety ground requirement of motor.Motor stator core press-fits fixing with mechanical means, be easy to generate bigger electromagnetic noise, metal material shell processing technology complexity.
The purpose of this utility model provides a kind of low noise small plastic shell motor, the sheathing material of its motor adopts plastics to utilize the mold hot pressure injection to form, can reduce the electromagnetic noise and the machinery noise of motor, improved the class of insulation of motor, can use on moist, seriously corroded ground, processing technology is simple, the production efficiency height.The use of motor can not need be considered earthing device.
The purpose of this utility model is such realization, and the end cap with one in the motor stator core of embedded line bag and motor utilizes plastics to form an integral body with mould heat pressure, and forms and as the shell of motor.The end cap of other end utilizes Luo Ding to be fixed on the plastic casing, and the bearing in the end cap of motor two is fixed on the rotor of motor in the stator core.Be characterized in being that the stator core of motor and line bag utilize the hermetically sealed hot pressing of plastics to form one, some spaces that produced after motor stator core press-fits are tamped by plastics, thereby have reduced the noise and the class of insulation that has improved motor of motor.
Because to adopt such scheme, changed the motor metal shell be plastic casing, reduced noise of motor, improved the class of insulation of motor, simplified processing technology.Enlarged the scope of application.
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 of the present utility modelly analyses and observe.
Among the figure 1, rear end cap 2, stator core 3, plastic casing 4, motor lines bag 5, Luo Ding 6, front end housing 7, bearing 8, rotating shaft 9, rotor 10, power supply lead wire.
In Fig. 1, motor lines bag (4) is embedded in the stator core (2), stator core (2) and rear end cap (1) with the good motor lines bag of embedding (4) utilizes plastic hot to be pressed into body again, and formation plastic casing (3), front end housing (6) is fixed on the plastic casing (3) with Luo Ding (5), and bearing (8) is enclosed within rear end cap (1) front end housing (6).Rotating shaft (8) on the rotor (9) is enclosed within on the bearing (8) of front end housing (6) and rear end cap (1).
Claims (3)
1, a kind of low noise small plastic shell motor, outer material is formed by sheet metal stretch or aluminium die casting metalworking, it is characterized in that: sheathing material adopts plastics to form with the mode of mold hot pressure injection, and with the iron core of stator be embedded in the stator core interior lines and wrap and form an integral body with the totally-enclosed hot pressing of plastics.
2, a kind of low noise small plastic shell motor as claimed in claim 1 is characterized in that the rear end cap hot pressing of motor is fixed in the plastic casing.
3, a kind of low noise small plastic shell motor as claimed in claim 1 is characterized in that the front end housing of motor is fixed on the plastic casing with Luo Ding.
