At present, the development of China's alternating-current permanent-magnet servo motor is in elementary developing stage, what the stator of conventional AC permanent-magnet servo motor adopted dispels the heat on motor case, as by radiating ribs is set on casing, increase the area of dissipation of motor etc., this radiator structure not only can strengthen the volume of motor, and owing to be to dispel the heat from the outside of stator, radiating effect is not fine.
The utility model content
The purpose of this utility model is the problems referred to above at prior art, provide a kind of simple in structure, under the situation that does not increase motor volume, improve the radiator structure of high power AC permanent-magnet servo motor stator of the radiating effect of stator.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals, a kind of radiator structure of high power AC permanent-magnet servo motor stator, comprise stator, stator adopts some stator punchings to be overrided to form, rear and front end at stator is respectively arranged with front end housing, rear end cap, the fan of band fan guard is installed on rear end cap, it is characterized in that: the middle part of stator punching is an installing hole, some louvres around installing hole, have been arranged at equably, after stator punching is superimposed, louvre has been formed several heat dissipation channels of stator, at front end housing, the position of the heat dissipation channel of the corresponding stator of rear end cap all is provided with thermovent to be connected with heat dissipation channel.
The utility model further is provided with as follows:
Wind by the strong cold blowing of radiator fan goes out through the thermovent of rear end cap, enters in the heat dissipation channel that louvre constituted by stator punching, is discharged by the thermovent of motor front end housing then.
Louvre is provided with two groups altogether, one group of four jiao of being arranged at stator punching, and each angle is provided with four holes, and another group is arranged between four jiaos the adjacent louvre, is provided with two holes between every adjacent two angles.
