Abstract
The utility model provides a kind of fixed structure of fixed motor stator, can improve the quality of product, increase the service life.The fixed structure of the motor stator, including front motor cover, motor stator and stator fixed cover, motor stator is fixed by stator fixed cover with front motor cover, the inwall along motor axial direction of front motor cover is provided with positioning convex tendon, positioning convex tendon is axially arranged along motor, and motor stator is provided with the detent being adapted to positioning convex tendon.The utility model is by setting and fixed screw positioning convex tendon in the same direction, motor stator can be provided to be positioned by the reaction force direction of rotor, so as to avoid the radial forces to fixed screw, prevent fixed screw from releasing caused motor stator and releasing, abnormal sound is avoided, improves fan electromotor product quality and service life.
Description
Technical field
It the utility model is related to fan electromotor design field, and in particular to a kind of fixed structure of motor stator.
Background technology
At present, the fan electromotor such as stand fan stator installation, be all by sequentially pass through stator fixed cover, motor stator and
The fixed screw of front motor cover is fixed.Motor stator in use, can be to fixed spiral shell by the reaction force of rotor
Silk produces the active force of radial direction, and long-term conventional, fixed screw can be deformed, and have one to the thread of fixed screw positioning hole
It is fixed to destroy, so as to cause fixed screw have it is a certain degree of release, cause motor stator to be fixed insecure, get loose cause it is different
Ring, influence quality and the life-span of product.
The content of the invention
The purpose of this utility model is to propose a kind of fixed structure of fixed motor stator, can improve the matter of product
Amount, increases the service life.
Consolidated according to the fixed structure of motor stator provided by the utility model, including front motor cover, motor stator and stator
Fixed lid, the motor stator are fixed by stator fixed cover with front motor cover, it is crucial be the front motor cover along motor shaft
To inwall be provided with positioning convex tendon, the positioning convex tendon is axially arranged along motor, the motor stator be provided with and the convex
The detent of muscle adaptation.
The utility model can be provided motor stator and turned by motor by setting and fixed screw positioning convex tendon in the same direction
The positioning in the reaction force direction of son, so as to avoid the radial forces to fixed screw, caused by preventing that fixed screw from releasing
Motor stator releases, and avoids abnormal sound, improves fan electromotor product quality and service life.
Specifically, the motor stator is by sequentially passing through stator fixed cover, motor stator and the screw of front motor cover
It is fixed.
Further, inwall uniform gap of the positioning convex tendon along the front motor cover is provided with multiple, so that stress is equal
It is even, holding structure stability.
Brief description of the drawings
Fig. 1 is stator structure schematic diagram of the present utility model.
Fig. 2 is fixed structure of stator schematic diagram of the present utility model.
Embodiment
Below against accompanying drawing, by the description to embodiment, to specific embodiment of the present utility model as involved by
The shape of each component, construction, the mutual alignment and annexation between each several part, the effect of each several part and operation principle etc. make
It is further to describe in detail.
Such as Fig. 1,2, the fixed structure of motor stator of the present utility model, including front motor cover 1, motor stator 2 and stator
Fixed cover 3, motor stator 2 are fixed by stator fixed cover 3 and front motor cover 1, and the inwall along motor axial direction of front motor cover 1 is set
There is positioning convex tendon 11, positioning convex tendon 11 is axially arranged along motor, and motor stator 2 is provided with the detent being adapted to positioning convex tendon 11
21。
The utility model can provide motor stator 2 by electricity by setting and the positioning convex tendon 11 in the same direction of fixed screw 4
The positioning in the reaction force direction of machine rotor, so as to avoid the radial forces to fixed screw 4, prevent fixed screw 4 from releasing
Caused motor stator releases, and avoids abnormal sound, improves fan electromotor product quality and service life.
Specifically, motor stator 2 is by sequentially passing through the screw 4 of stator fixed cover 3, motor stator 2 and front motor cover 1
It is fixed, as shown in Figure 2.In Fig. 1, fixing hole 22 is mounting hole of the fixed screw 4 on motor stator 2.
As preferred embodiment, inwall uniform gap of the positioning convex tendon along front motor cover 1 is provided with 4, so that stress
Uniformly, holding structure stability.
