Description

Technical Field

[0001] This utility model relates to the field of high-voltage motor technology, specifically a high-voltage motor capable of brushless excitation synchronization. Background Technology

[0002] With the rapid development of my country's economy and motor industry, the demand for high-voltage motors is increasing. The balance of high-voltage motor rotors is required to be high in national standards. Currently, the commonly used method for installing balance blocks is to set multiple connecting parts at intervals at the ends of the high-voltage motor rotor. The balance blocks are installed by connecting to the connecting parts. The installation of the above-mentioned balance blocks is limited, and the angle of the connecting parts relative to the rotor center is fixed, which has certain limitations for balance correction and cannot achieve precise adjustment of balance, thus affecting the adjustment accuracy of the high-voltage motor rotor balance.

[0003] Most existing high-voltage motors are asynchronous motors, which can cause excessive starting current during equipment startup, leading to startup failure or even accidents.

[0004] Therefore, those skilled in the art have provided a high-voltage motor capable of brushless excitation synchronization to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a high-voltage motor with brushless excitation synchronization, in order to solve the problem mentioned in the background art that most existing high-voltage motors are asynchronous motors, which cause excessive starting current during equipment startup, resulting in startup failure or even accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-voltage motor capable of brushless excitation synchronization includes: a high-voltage motor housing; a motor output shaft installed inside the high-voltage motor housing; a brushless exciter installed on one side of the high-voltage motor; a housing installed at one end of the brushless exciter; a shaft installed inside the housing; a worm gear fixedly installed on the surface of the shaft; a worm wheel installed below the worm gear; a rotor mounted at one end of the shaft; an excitation rotor winding disposed on the surface of the rotor; a magnetic wheel seat mounted on the outer side of the rotor; and an excitation stator winding disposed on the surface of the magnetic wheel seat.

[0008] As a further improvement of this utility model: the rotating base and the shaft are fixedly connected, and there are a total of three sets of excitation stator windings and excitation rotor windings.

[0009] As a further improvement of this utility model: the worm and the shaft are fixedly connected, and the worm and the worm wheel are meshed.

[0010] As a further improvement of this utility model, the worm gear is fixedly connected to the non-output end of the motor output shaft.

[0011] As a further improvement of this utility model: a support base is installed at the bottom of the high-voltage motor housing, and a load-bearing base is installed below the brushless exciter.

[0012] As a further improvement of this utility model: the two sides of the surface of the load-bearing seat are integrally connected with side ears, a support is fixedly installed inside the load-bearing seat, and a support plate is installed below the support.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The high-voltage motor and the brushless exciter are installed together. By setting up the brushless exciter, it is convenient to start the high-voltage motor with brushless excitation synchronous start, so as to meet the synchronous operation of the device and the motor and achieve the purpose of safe start.

[0015] 2. By utilizing the transmission cooperation between the worm and worm wheel, the brushless exciter is installed at one end of the high-voltage motor's non-output shaft, thus enabling the brushless exciter to drive the high-voltage motor to start. The worm and worm wheel configuration eliminates the need to directly install the brushless exciter on the non-output shaft, avoiding excessive weight increase to the high-voltage motor. This ensures synchronous operation of the high-voltage motor while reducing its stress and improving its safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a high-voltage motor with brushless excitation synchronization, including: a high-voltage motor housing 1, a motor output shaft 2 installed inside the high-voltage motor housing 1, a brushless exciter 4 installed on one side of the high-voltage motor, a housing 6 installed at one end of the brushless exciter 4, a shaft 7 installed inside the housing 6, a worm gear 8 fixedly installed on the surface of the shaft 7, a worm wheel 9 installed below the worm gear 8, a rotating base 12 installed at one end of the shaft 7, an excitation rotor winding 13 provided on the surface of the rotating base 12, a magnetic wheel seat 10 installed on the outside of the rotating base 12, and an excitation stator winding 11 installed on the surface of the magnetic wheel seat 10.

[0023] The rotary seat 12 is fixedly connected to the shaft 7, and there are three sets of excitation stator winding 11 and excitation rotor winding 13. The worm 8 is fixedly connected to the shaft 7, and the worm 8 is meshed with the worm wheel 9.

[0024] The three sets of excitation stator windings 11 and excitation rotor windings 13 cooperate to form a three-phase winding. The magnetic field between the stator and rotor drives the shaft 7 to rotate. The shaft 7 is connected to the worm 8, and the meshing structure between the worm 8 and the worm wheel 9 drives the worm wheel 9 to rotate.

[0025] The worm gear 9 is fixedly connected to the non-output end of the motor output shaft 2;

[0026] The worm 8 and the worm wheel 9 are meshed. The worm 8 drives the worm wheel 9 to rotate. The worm wheel 9 is connected to the motor output shaft 2, which in turn drives the motor output shaft 2 to rotate, thereby synchronously driving the brushless exciter 4 to run the high-voltage motor.

[0027] A support base 3 is installed at the bottom of the high-voltage motor housing 1, a load-bearing base 5 is installed below the brushless exciter 4, side ears 501 are integrally connected to both sides of the surface of the load-bearing base 5, a bracket 502 is fixedly installed inside the load-bearing base 5, and a support plate 503 is installed below the bracket 502.

[0028] A support base 3 is provided below the high-voltage motor housing 1 to improve the stability of the high-voltage motor during operation. At the same time, a load-bearing base 5 is provided below the brushless exciter 4 to support the brushless exciter 4, reduce the pressure of the brushless exciter 4 on the high-voltage motor, and avoid the synchronous structure of the brushless exciter 4 and the high-voltage motor affecting the weight of the high-voltage motor itself.

[0029] The working principle of this utility model is as follows: When using this utility model, the magnetic field between the three sets of excitation stator windings 11 and excitation rotor windings 13 is used to drive the rotating base 12 to rotate. The rotating base 12 is connected to the shaft 7, thereby driving the shaft 7 to rotate. The shaft 7 is connected to the worm 8, and the meshing structure between the worm 8 and the worm wheel 9 is used to drive the worm wheel 9 to rotate. The worm wheel 9 is connected to the motor output shaft 2. The meshing connection between the worm 8 and the worm wheel 9 means that the rotation of the worm 8 will synchronously drive the rotation of the worm wheel 9, thereby driving the rotation of the motor output shaft 2. In this way, the brushless exciter 4 can start the high-voltage motor with brushless excitation synchronous start, satisfying the synchronous operation of the device and the motor, thereby safely starting the high-voltage motor and further achieving the purpose of safe start.
