Background technology
As everyone knows; In the more and more general life that has been used in people of the present increasing electric equipment products of the continuous progress of social productive forces; The electrical equipment that electric fan comes to this, electric fan is by driven by power, thereby and convert electrical energy into wind energy and can under the weather condition of sweltering heat, lower the temperature for people; All include motor, flabellum and base in its structure of electric fan; Flabellum is connected on the power output shaft of motor, converts electrical energy into wind energy thereby rotate by the driven by motor flabellum when in use, and motor all has shell in practical implementation; Be provided with parts such as coil in the shell; All utilize some auxiliary fixing structures to fix for the flabellum with electric fan is fixed on way traditional in the rotating shaft of motor, but this syndeton annexation is too complicated and can security incident take place because annexation is uneasy, and this is the major defect for conventional art.
The utility model content
The utility model provides a kind of rotational structure of fan electromotor, and its overall structure is simple, annexation safety, and this is the main purpose of the utility model.
The technical scheme that the utility model is taked is: a kind of rotational structure of fan electromotor; It comprises the motor back seat and rotates protecgulum; The rotating front end that is arranged on this motor back seat of this rotation protecgulum; In concrete the use, fan blade is fixedly connected on this rotations protecgulum, thus when this rotate protecgulum when rotating fan blade rotate protecgulum rotation generation synchronously wind energy with this.
This motor back seat comprises central retainer ring and protective ring; This central authorities' retainer ring has inner chamber; Machine shaft is through in rotating this inner chamber that is arranged on this central authorities' retainer ring of bearing; This rotation protecgulum is fixedly connected on the front end of this machine shaft, is set with motor stator on the outer surface of this central authorities' retainer ring.
This rotation protecgulum comprises top cover and ring wall; This ring wall is fixedly connected on this top cover, and is corresponding with this motor stator, and the inner surface of this ring wall is provided with rotor; In concrete work; By electromagnetic induction principle in energising by the corresponding relation between this motor stator and this rotor, this rotor is rotated, owing to this rotor is fixedly connected on this rotation protecgulum with respect to this motor stator; So drive synchronously should be rotated by the rotation protecgulum when this rotor rotates, and then drive the fan blade rotation.
The rear end of this ring wall of this rotation protecgulum reaches dustproof through such structure setting and prevents that foreign matter from getting into the effect of motor internal between this central authorities' retainer ring and this protective ring of this motor back seat in practical implementation.
Be set with projection on this top cover of this rotation protecgulum; Fan blade is fixed on this projection, and in practical implementation, this projection comprises three fixed legs and reference column; Three these fixed legs and this reference column are fixedly installed on this top cover; Wherein, this reference column is arranged on the central authorities of this top cover, and three these fixed legs disperse to be arranged on this reference column around.
The beneficial effect of the utility model is: as stated because the utility model comprises motor back seat and rotation protecgulum; The rotating front end that is arranged on this motor back seat of this rotation protecgulum; In concrete the use, fan blade is fixedly connected on this rotations protecgulum, thus when this rotate protecgulum when rotating fan blade rotate protecgulum rotation generation synchronously wind energy with this; It is simple that it has overall structure, the characteristics of annexation safety.

Embodiment
Shown in Fig. 1 to 3, a kind of rotational structure of fan electromotor, it comprises motor back seat 10 and rotates protecgulum 20, these rotation protecgulum 20 rotating front ends that are arranged on this motor back seat 10.
In concrete the use, fan blade is fixedly connected on this rotations protecgulum 20, thus when this rotate protecgulum 20 when rotating fan blade rotate protecgulum 20 rotation generation synchronously wind energies with this.
This motor back seat 10 comprises central retainer ring 30 and protective ring 40.
This central authorities' retainer ring 30 has inner chamber, and machine shaft 51 is through in rotating this inner chamber that is arranged on this central authorities' retainer ring 30 of bearing 52.
This rotation protecgulum 20 is fixedly connected on the front end of this machine shaft 51.
Be set with motor stator 53 on the outer surface of this central authorities' retainer ring 30.
This rotation protecgulum 20 comprises top cover 21 and ring wall 22, and this ring wall 22 is fixedly connected on this top cover 21.
Corresponding with this motor stator 53, the inner surface of this ring wall 22 is provided with rotor 54.
In concrete work; By electromagnetic induction principle the energising in by the corresponding relation between this motor stator 53 and this rotor 54; This rotor 54 is rotated with respect to this motor stator 53; Because this rotor 54 is fixedly connected on this rotation protecgulum 20,, and then drive the fan blade rotation so drive synchronously should be rotated protecgulum 20 rotations in the time of these rotor 54 rotations.
The rear end of this ring wall 22 of this rotation protecgulum 20 reaches dustproof through such structure setting and prevents that foreign matter from getting into the effect of motor internal between this central authorities' retainer ring 30 and this protective ring 40 of this motor back seat 10 in practical implementation.
