The purpose of this utility model is achieved in that a kind of industrial fan electromotor, comprise front shroud (1), back cover (2), motor fore shell (3), motor back cover (4), stator (5), be positioned at the rotor (6) in the middle of the stator (5) and be fixed on rotating shaft (7) on the rotor (6), it is characterized in that: described motor fore shell (3) and motor back cover (4) opposing end faces have had the flange of the effect of being connected and fixed respectively, offer connecting hole on the flange, described stator (5) lateral wall is a polygon, offer through hole (50) on the exterior angle of stator (5), stator is positioned between motor fore shell (3) and the motor back cover (4), and the through hole of stator is over against the connecting hole of flange, motor fore shell (3) and motor back cover (4) are by passing through hole, the locking of the threaded fastening device of connecting hole, the two ends side of described stator (5) respectively with motor fore shell (3), has heat transmission air channel (90) between the inner edge of motor back cover (4).
Have the circular projection of location usefulness on the connecting hole of described motor fore shell (3), motor back cover (4), this circular projection is plugged in the through hole (50) of stator (5).
The sidewall of described motor fore shell (3) offers screwed hole (33), and front shroud (1) is positioned at the screwed hole position and offers through hole (10), and back shaft (8) passes on the screwed hole (33) that through hole (10) rear thread is fastened on motor fore shell (3).
The flange of described motor fore shell (3), motor back cover (4) is provided with reinforcement.
Described reinforcement is ring-type or is that mid point radially distributes with the center of circle.
The polygon of described stator (5) lateral wall is square.
The polygon of described stator (5) lateral wall is a triangle.
Described threaded fastening device is screw rod (91), nut (92) structure that is connected, and screw rod (91) passes behind connecting hole, the through hole by nut (92) locking.
Good effect of the present utility model is: stator is fixed on the flange between motor fore shell and the motor back cover, make the spacing that has stator thickness between motor fore shell and the motor back cover, has the heat transmission air channel between the inner edge of the side of stator and motor fore shell and motor back cover, can increase the heat radiation position, therefore, radiating effect strengthens greatly, has effectively improved the useful life of motor.
As further improvement of the utility model, back shaft directly is fixed on the motor fore shell, because the main weight of motor all concentrates on the motor front and rear casing, rather than on the front shroud, therefore, mechanical strength to front shroud requires to reduce greatly, can be with front shroud and back cover design thickness attenuate, and cost saves material.
