【Utility model content】

The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of micro- Type synchronous motor, has the advantages that simple in construction, easy for installation and fixed.

The utility model solves the technical scheme that the technical problem uses：

A kind of small synchronous motor is provided, including the rotor assembly provided with rotating shaft, the fore-stock provided with fore bearing room, is provided with Afterwards the after-poppet of bearing chamber, be installed on the fore-stock before fore bearing in bearing chamber and be installed on the rear axle of the after-poppet Hold the rear bearing of interior, and the stator module being installed between the fore-stock and after-poppet；The stator module includes fixed Sub- iron core and two stator winding units, the stator core lower end are U-shaped, and the stator core upper end includes and described turn The central through hole of sub-component adaptation and the breach being inserted in for the stator winding unit, the breach are connected with the central through hole It is logical, the central through hole of the stator core upper end and the opening in communication of the U-shaped of the stator core lower end；The rotor set The rotating shaft rear and front end of part is located in the endoporus of the endoporus of the fore bearing and rear bearing respectively, so that the rotor assembly turns It is arranged on dynamicly between the fore-stock and after-poppet；The fore-stock upper end upper positioning convex before being provided with two, the rear branch Frame upper end upper positioning convex after also being provided with two；When micro electric synchronous machine is assembled, the fore-stock two at before upper positioning convex Be inserted into one end of the breach of the stator core, and this at two before upper positioning convex respectively against the two of described breach one end Sideways, similarly, at the two of the after-poppet after upper positioning convex be inserted into the stator core breach the other end, and should Upper positioning convex, then will the preceding branch by screw and nut respectively against the two sides of the breach other end after at two Frame, the stator core of stator module and after-poppet are fixed together.

In order to prevent it is each before before upper positioning convex fracture and increase upper positioning convex intensity, the fore-stock two at before Upper positioning convex connects into an entirety, forms the preceding upper positioning boss 39A of one piece of projective table type.

In order to prevent it is each after after upper positioning convex fracture and increase upper positioning convex intensity, the after-poppet two at after Upper positioning convex connects into an entirety, forms the rear upper positioning boss of one piece of projective table type.

In order to more position the stator core and after-poppet of fore-stock and stator module and the stator core of stator module And spacing, front lower positioning boss of the fore-stock lower end provided with one piece of projective table type, the after-poppet lower end also be provided with one piece it is convex Desk-top rear lower positioning boss；When micro electric synchronous machine is assembled, the front lower positioning boss of the fore-stock is inserted into the stator One end of the opening of the U-shaped of iron core lower end, and the front lower positioning boss two sides respectively against the opening of the U-shaped The two sides of one end, similarly, the rear lower positioning boss of the after-poppet are inserted into the opening of the U-shaped of the stator core lower end The other end, and the rear lower positioning boss two sides respectively against the U-shaped the opening other end two sides.

Compared with the existing technology compared with the beneficial effect of the utility model small synchronous motor is：

First, due to fore-stock upper end provided with insert and lean against stator core breach two at before on positioning convex, with And after-poppet upper end also be provided with inserting and lean against at the two of the breach of stator core after upper positioning convex so that fore-stock and stator There is accurate positioning between the stator core and after-poppet of component and the stator core of stator module so that easy to assembly, reduce Time during assembling, while also make fixed between fore-stock, the stator core of stator module and after-poppet；

2nd, upper positioning convex before at the two of fore-stock is connected into an entirety, forms the preceding upper positioning of one piece of projective table type Boss, it is therefore prevented that the hidden danger that upper positioning convex is broken before each and the intensity for adding preceding upper positioning convex；

3rd, upper positioning convex after at the two of after-poppet is connected into an entirety, forms the rear upper positioning of one piece of projective table type Boss, it is therefore prevented that upper positioning convex is broken after each hidden danger and the intensity that positioning convex is gone up after adding；

4th, due also in the front lower fixed of opening of the fore-stock lower end provided with the U-shaped for inserting and being stuck in stator core lower end Position boss, and after-poppet lower end are provided with the rear lower positioning boss of the opening for the U-shaped for inserting and being stuck in stator core lower end, more Plus cause there is accurate positioning between fore-stock and the stator core and after-poppet of stator module and the stator core of stator module With it is spacing so that assembling is more convenient, while also making fixation between fore-stock, the stator core of stator module and after-poppet more firm Lean on.

In summary, the utility model small synchronous motor has the advantages that simple in construction, easy for installation and fixed.
