Description

A kind of motor

Technical field

The utility model relates to a kind of motor, especially a kind of heat radiation and the good motor of moisture effect.

Background technology

Motor is a kind of common apparatus commonly used; be widely used in the industrial industry-by-industry; the motor in use quality of heat dispersion has directly determined useful life of motor; the radiating mode that motor of the prior art adopts generally all is that a fan is installed in the rear end cap of motor; heat radiation when the rotation that drives flabellum by electric machine main shaft realizes machine operation; fan and motor were coaxial rotation when but this form was dispelled the heat; being motor has dispelled the heat once beginning; and motor just must dispel the heat after reaching uniform temperature in actual production; this moment, the heat radiation of this form was just relatively consumed energy; and the rear end cap of motor of the prior art generally all offers louvre; in the face of relatively moister environment; airborne moisture enters motor internal through regular meeting by louvre; cause motor to make moist; also can cause the motor internal line short when serious, cause danger.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of have automatic control heat sinking function and the good motor of humidity resistance are provided.

For achieving the above object, the technical solution of the utility model is:

A kind of motor, comprise shell, front end housing, rear end cap, main shaft, be positioned at the housing of shell, be equiped with rotor assembly in the housing, offer louvre on the described rear end cap, be provided with sealing ring between housing and the main shaft, described rear end cap is fixed on the shell by screw, in the inner chamber of rear end cap temperature sensing device is installed, and the induction end of described temperature sensing device is positioned at housing, the control end of temperature sensing device links to each other with the heat radiation motor, on the described heat radiation motor fan blade is installed, the centre of described rear end cap also is provided with a drying box, fills silica gel in the drying box.

The beneficial effects of the utility model are: a heat radiation motor is installed in the cavity of back end cover for motor specially work drive motor is dispelled the heat, by temperature sensing device it is controlled, when temperature was too high, the heat radiation motor was opened, heat sinking function starts, good heat dissipation effect and energy-conservation; A drying box is installed on the rear end cap, and in drying box, is held drier silica gel, even in the face of very moist environment can guarantee that also motor moves under the environment of drying, improved security performance.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: shell 1, front end housing 2, rear end cap 3, louvre 31, screw 32, main shaft 4, housing 5, rotor assembly 6, temperature sensing device 7, heat radiation motor 8, fan blade 81, drying box 9.

Embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment:

As shown in Figure 1, a kind of motor, comprise shell 1, front end housing 2, the housing 5 that is positioned at shell 1 is equiped with on the described rear end cap 3 and offers louvre 31, be provided with sealing ring 51 between housing 5 and the main shaft 4, described rear end cap 3 is fixed on the shell 1 by screw 32, temperature sensing device 7 is installed in the inner chamber of rear end cap 3, the induction end of described temperature sensing device 7 is positioned at housing 5, and the control end of temperature sensing device 7 links to each other with heat radiation motor 8, on the described heat radiation motor 8 fan blade 81 is installed, the centre of described rear end cap 3 also is provided with a drying box 9, fills silica gel in the drying box 9.

The utility model provides by heat radiation motor 8 and specially work drive motor is dispelled the heat, radiating effect is better, and heat radiation motor 8 is controlled by temperature sensing device 7, saved energy, be equiped with drying box 9 on the rear end cap 3, be placed with silica-gel desiccant in the drying box 9, surrounding environment is carried out drying, guarantee that motor moves in the environment of drying, promoted the security performance of motor, rear end cap 3 is by on screw 32 fixed housings 1, and convenient disassembly is convenient to the replacing of the drier in the rear end cap 3 and cleaning, the maintenance of heat radiation motor 8.
