Description
Technical field
The utility model relates to machine field, particularly relates to a kind of threephase asynchronous machine.
Background technology
Threephase asynchronous machine is a class motor of powering by accessing 380V three-phase alternating-current supply simultaneously, because the rotor of threephase asynchronous machine becomes to rotate with identical direction, different rotating speeds from stator rotating magnetic field, there is revolutional slip, so be threephase asynchronous machine; Threephase asynchronous machine commonly used on the market at present, have larger defect at this block of heat radiation, often can make burn-down of electric motor because of the high temperature of the too high generation of rotating speed, more severe patient is even quick-fried, not only wastes Financial cost, there is potential safety hazard simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of threephase asynchronous machine, and its structure is simple, easily manufactured, is dispelled the heat, not only increase the normal service life of motor by multiple heat dissipation mode to motor, has also stopped potential safety hazard simultaneously.
In order to achieve the above object, the technical solution of the utility model is:
A kind of threephase asynchronous machine, comprises electric machine casing and is arranged on the fan housing on electric machine casing; The two ends of described housing are provided with left and right end cap, and described left and right end cap is provided with left and right bearing separately; Between described left and right bearing, armature spindle is installed, described armature spindle is provided with rotor core; Described electric machine casing is also provided with terminal box, stator core; The gap of 3-5mm is provided with between described stator core and rotor core; In described fan housing, radiator fan is installed; Also elastic washer is installed in described housing; The top of described housing also offers louvre.
The outer surface of described housing starts there is radiating groove.
Described housing is also provided with handle.
The beneficial effects of the utility model are: its structure of the utility model is simple, easily manufactured, is dispelled the heat, not only increase the normal service life of motor by multiple heat dissipation mode to motor, have also stopped potential safety hazard simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A threephase asynchronous machine as shown in Figure 1, the fan housing 2 comprising electric machine casing 1 and be arranged on electric machine casing 1; The two ends of described housing 1 are provided with left and right end cap 4,5, and described left and right end cap 4,5 is provided with left and right bearing 6,7 separately; Between described left and right bearing 6,7, armature spindle 8 is installed, described armature spindle 8 is provided with rotor core 9; Described electric machine casing 1 is also provided with terminal box 10, stator core 11; Be provided with the gap of 3-5mm between described stator core 11 and rotor core 9, be convenient to heat radiation; In described fan housing 2, radiator fan 12 is installed, for heat radiation; In described housing 1, elastic washer 3 is also installed, plays anti-riot effect; The top of described housing 1 also offers louvre 13, is convenient to heat radiation.
The outer surface of described housing 1 starts there is radiating groove 14, is convenient to motor radiating, prevent Yin Wendu too high and burst.
Described housing 1 is also provided with handle 15, facilitates motor to install and remove and carrying.
A kind of threephase asynchronous machine of the present embodiment, its structure is simple, easily manufactured, is dispelled the heat, not only increase the normal service life of motor by multiple heat dissipation mode to motor, has also stopped potential safety hazard simultaneously.
