Abstract
The utility model discloses a stator fanning strip ventilation duct plate, comprising a ventilation duct plate body of fan-shaped structure and ventilation duct sheets arranged on the ventilation duct plate body. An outer arc surface of the ventilation duct plate body is provided with cylindrical square slots for positioning core fixing plates. The ventilation duct plate body is also provided with circular holes for assembling a core straining device. The ventilation duct sheets are at least two bent ventilation duct sheets, the bending directions of the two bent ventilation duct sheets are opposite, and the cylindrical square slots, corresponding to the two bent ventilation duct sheets, are provided with the core fixing plates. The utility model also provides a stator core ventilation duct plate. The bent ventilation duct sheets guide air flows blocked by the fixing plates to sides of the fixing plates, so that smooth pathways are formed and wind resistance is reduced, thereby effectively reducing temperature rise in a motor. The bent ventilation duct sheets increases the contact area between the stator core and the air, and core loss and eddy-current loss of the core are taken away rapidly by the air. Ventilation and heat radiation effects of the motor are improved, and service life of the motor is further prolonged.
