Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a direct-drive rotary table integrated permanent magnet rotor. Background Technology

[0002] In recent years, with the development of the motor industry, the requirements for motors have become increasingly stringent. Traditional motors have a relatively complex structure with many parts, making assembly cumbersome and prone to problems. This has a significant impact on motor production efficiency and quality.

[0003] Therefore, developing a novel direct-drive rotary table integrated permanent magnet rotor is of great significance. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated permanent magnet rotor for direct-drive rotary tables to solve the problems existing in the prior art.

[0005] The technical solution adopted to achieve the purpose of this invention is as follows: a direct-drive rotary table integrated permanent magnet rotor, including a frame, magnets, rotating bearings, encoder shaft, encoder and stator core.

[0006] The base includes a base body. The base body is an integral cylindrical ring. A stop ring extends inward from the inner wall of the inner cavity of the base body. A receiving chamber is provided on the upper surface of the base body. The receiving chamber has an annular stepped structure. The outer circumferential wall of the receiving chamber is provided with a groove for transitional fit with the stator core, and the inner circumferential wall is provided with a groove for transitional fit with the rotating bearing.

[0007] The inner ring of the stator core has a winding groove, and the outer ring has a protrusion on its peripheral wall. The stator core is arranged in a receiving chamber. The outer ring of the stator core is in close contact with the outer peripheral wall of the receiving chamber.

[0008] A magnet is bonded to the outer ring of the rotary bearing. The rotary bearing is arranged in a receiving chamber. The inner ring of the rotary bearing is in close contact with the inner circumferential wall of the receiving chamber. The rotary bearing is connected to the machine base with screws.

[0009] The encoder shaft includes a shaft body and a support flange. The shaft body extends into the inner cavity after passing through the stop ring. The upper end of the shaft body extends outward to form a support flange, and the lower end is fitted with an encoder.

[0010] Furthermore, a hydrostatic support block is also provided between the rotating bearing and the machine base.

[0011] Furthermore, the lower outer wall of the base body is provided with support feet.

[0012] The technical advantages of this invention are undeniable: it ensures that the entire assembly rotates at the same speed when energized. It also enables rapid assembly of the integrated permanent magnet rotor, minimizing time consumption. Attached Figure Description

[0017] The present invention will be further described below with reference to embodiments, but it should not be construed that the scope of the present invention is limited to the following embodiments. Various substitutions and modifications made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention should be included within the scope of protection of the present invention.

[0018] Example 1:

[0019] See Figure 1 and Figure 2 This embodiment provides an integrated permanent magnet rotor for direct drive turntable, including a base 1, a magnet 2, a rotating bearing 3, an encoder shaft 4, an encoder 5, and a stator core 6.

[0020] See Figure 3 The base 1 includes a base body. The base body is an integral cylindrical ring. A stop ring 103 extends inward from the inner wall of the inner cavity 101 of the base body. A receiving chamber 102 is provided on the upper surface of the base body. The receiving chamber 102 has an annular stepped structure. The outer circumferential wall of the receiving chamber 102 is provided with a groove for transitional fitting with the stator core 6, and the inner circumferential wall is provided with a groove for transitional fitting with the rotating bearing 3.

[0021] The inner ring of the stator core 6 has a winding groove, and the outer ring has a protrusion on its peripheral wall. The stator core 6 is arranged in the receiving chamber 102. The outer ring of the stator core 6 is in close contact with the outer peripheral wall of the receiving chamber 102.

[0022] A magnet 2 is bonded to the outer circumferential wall of the rotary bearing 3. The rotary bearing 3 is arranged in the accommodating chamber 102. The inner ring of the rotary bearing 3 is in close contact with the inner circumferential wall of the accommodating chamber 102. The rotary bearing 3 is connected to the machine base 1 with screws to ensure that both can rotate at the same speed.

[0023] The encoder shaft 4 includes a shaft body and a support flange. The shaft body passes through the stop ring 103 and extends into the inner cavity 101. The upper end of the shaft body extends outward to form a support flange, and the lower end is fitted with an encoder 5.

[0024] Once powered on, magnet 2 generates a magnetic field, causing the entire assembly to rotate at the same speed. This ultimately achieves the rotation of the integrated permanent magnet rotor. This embodiment not only possesses the functions of a traditional rotor but also features a simple structure, convenient assembly, and fast response speed. It is simple in structure and economical to apply.

[0026] The main content of this embodiment is the same as that of embodiment 1, wherein a static pressure support block is also provided between the rotating bearing 3 and the base 1.

[0027] Example 3:

[0028] The main content of this embodiment is the same as that of embodiment 1, wherein a support leg 104 is provided on the lower outer wall of the base body.
