Description

Technical Field

[0001] The utility model relates to a synchronous motor provided with a shrapnel. Background Art

[0002] A synchronous motor is an AC motor whose rotor speed remains constantly synchronized with the grid frequency. As an important component in the power system, the synchronous motor has the characteristics of high efficiency and stability and is widely used in fields such as power generation and industrial drive. A rotor is provided inside the synchronous motor, and the rotor is composed of magnets. During the high-speed rotation of the rotor, the magnets are prone to adsorbing to the motor housing, resulting in the rotor being stuck. Summary of the Invention

[0003] The utility model provides a synchronous motor provided with a shrapnel.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0005] A synchronous motor provided with a shrapnel includes a housing. A rotor is provided inside the housing. A shrapnel is provided between the housing and the rotor. The shrapnel includes a circular sheet and support feet distributed on the side of the circular sheet. A through hole is provided on the circular sheet. The support feet are inclined towards the axial direction of the circular sheet, and the ends of the support feet abut against the bottom of the housing.

[0006] Preferably, a gear set is provided inside the housing. The gear set is composed of multiple meshing gears, and the gear set is provided with an output shaft.

[0007] Preferably, a drive shaft is provided at the top of the rotor. A drive gear meshing with the gear set is provided on the drive shaft. A positioning shaft is provided at the bottom of the rotor. The through hole of the circular sheet cooperates with the positioning shaft.

[0008] Preferably, the housing includes a circular cavity and an end cover fixed on the circular cavity. A circular hole cooperating with the output shaft is provided on the end cover.

[0009] Preferably, the angle between the support feet and the circular sheet is 10° - 85°, and the support feet are in a T shape.

[0010] Preferably, there are three support feet and they are evenly distributed at intervals on the outside of the circular sheet.

[0011] Compared with the prior art, the synchronous motor provided with a shrapnel in the utility model can avoid the adsorption of the magnets on the rotor to the housing and reduce the resistance of the rotor by providing a shrapnel between the housing and the rotor. The shrapnel can stably support the rotor and space the rotor from the housing. The structure of the synchronous motor is simple and the working efficiency is high. Brief Description of the Drawings

[0016] The present utility model will be further described in detail below in conjunction with the embodiments in the drawings.

[0017] As Figures 1 to 4 shown, a synchronous motor with a shrapnel includes a housing 1, a rotor 2 and a gear set 3 are arranged inside the housing 1. The gear set 3 is composed of multiple meshing gears, and the gear set 3 is provided with an output shaft 31. A shrapnel 4 is arranged between the housing 1 and the rotor 2. The shrapnel 4 includes a circular sheet 41 and support feet 42 distributed on the side of the circular sheet 41. A through hole 411 is arranged on the circular sheet 41. There are three support feet 42 and they are evenly distributed at intervals on the outside of the circular sheet 41. The support feet 42 are inclined towards the axial direction of the circular sheet 41, and the angle between the support feet 42 and the circular sheet 41 is 10° - 85°. The support feet 42 are in a T shape so as to stably support the rotor 2. The ends of the support feet 42 abut against the bottom of the housing 1, so that the shrapnel 4 can separate the rotor 2 from the bottom of the housing 1.

[0018] The housing 1 includes a circular cavity 11 and an end cover 12 fixed on the circular cavity 11. A circular hole 121 matching the output shaft 31 is arranged on the end cover 12.

[0019] A drive shaft 21 is arranged at the top of the rotor 2. A drive gear meshing with the gear set 3 is arranged on the drive shaft 21. A positioning shaft (not shown in the figure) is arranged at the bottom of the rotor 2. The through hole 411 of the circular sheet 41 cooperates with the positioning shaft.

[0020] By arranging the shrapnel 4 between the housing 1 and the rotor 2 in the synchronous motor with a shrapnel of the present utility model, the shrapnel 4 can stably support the rotor 2 and separate the rotor 2 from the housing 1, so as to avoid the adsorption of the magnet on the rotor 2 to the housing 1, reduce the resistance of the rotor 2, and the structure of the synchronous motor is simple and the working efficiency is high.

[0021] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
