Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] Please refer to Figures 1 to 5. This application provides a frameless torque motor test assembly 100, which is applied to motor testing equipment and used for testing frameless torque motors.

[0041] Please refer to Figures 1-5. In this embodiment, the frameless torque motor test assembly 100 includes a housing 10, a rotating shaft 20, a bearing 30, a motor stator 40, a motor mover 50, and an encoder 60. The housing 10 has a receiving space 10a and a rotating hole 10b. The rotating shaft 20 is rotatably connected to the housing 10 and passes through the rotating hole 10b. The rotating shaft 20 has a first rotating part 21, which is located on the outside of the housing 10. The bearing 30 is located between the housing 10 and the rotating shaft 20, and is sleeved on the rotating shaft 20 and connected to the housing 10. The motor stator 40 is located within the receiving space 10a and installed on the housing 10. The mover 50 is located within the receiving space 10a and is mounted on the rotating shaft 20; the motor mover 50 rotates relative to the motor electronics and magnetically induces with the motor electronics; the encoder 60 includes an encoder mover 61 and an encoder stator 62, the encoder mover 61 is mounted on the first rotating part 21 and rotates with the rotation of the first rotating part 21; the encoder mover 61 is located on the outside of the housing 10; the encoder stator 62 is mounted on the outside of the housing 10 and close to the encoder mover 61, the encoder mover 61 rotates relative to the encoder stator 62 so that the encoder 60 is arranged relative to the outside of the housing 10, reducing the gap between the motor stator 40 and the motor mover 50.

[0042] Please refer to Figures 1 to 5. In this embodiment, the housing 10 serves as a support component of the frameless torque motor test assembly 100. The housing 10 is used to support the rotating shaft 20, bearing 30, motor stator 40, motor mover 50, and encoder 60. The housing 10 is provided with a receiving space 10a and a rotating hole 10b; the rotating hole 10b is connected to the receiving space 10a.

[0043] The rotating shaft 20 is rotatably connected to the housing 10 so as to adjust the position of the rotating shaft 20 relative to the housing 10. The rotating shaft 20 passes through the rotating hole 10b so that both ends of the rotating shaft 20 are exposed to the outside of the housing 10. The rotating shaft 20 is provided with a first rotating part 21, which is located on the outside of the housing 10.

[0044] The bearing 30 is located between the housing 10 and the rotating shaft 20. The bearing 30 is sleeved on the rotating shaft 20 and connected to the housing 10 so that the rotating shaft 20 can rotate relative to the housing 10 under the action of the bearing 30, thereby improving the smoothness of the rotation of the rotating shaft 20.

[0045] The motor stator 40 is located within the receiving space 10a and is installed on the housing 10, so that the motor stator 40 can be fixed to the inside of the housing 10 through the receiving space 10a, thereby making full use of the receiving space 10a.

[0046] The motor mover 50 is located within the receiving space 10a. The motor mover 50 makes full use of the receiving space 10a. The motor mover 50 is installed on the rotating shaft 20 so that the motor mover 50 is in a fixed state relative to the rotating shaft 20, thereby facilitating the rotation of the motor mover 50 with the rotation of the rotating shaft 20. The motor mover 50 rotates relative to the motor electronics and undergoes magnetic induction with the motor electronics.

[0047] The encoder 60 includes an encoder mover 61 and an encoder stator 62. The encoder mover 61 is mounted on the first rotating part 21 and rotates with the rotation of the first rotating part 21. The encoder mover 61 is located on the outside of the housing 10. The encoder stator 62 is mounted on the outside of the housing 10 and close to the encoder mover 61. The encoder mover 61 rotates relative to the encoder stator 62 so that the encoder 60 can be arranged relative to the outside of the housing 10, thereby reducing the gap between the motor stator 40 and the motor mover 50.

[0048] Please refer to Figures 1-5. In this embodiment, the housing 10 includes an outer shell portion 11 and an end cap portion 12. The end cap portion 12 is disposed on the upper side of the outer shell portion 11 and is detachably connected to the outer shell portion 11 so that the end cap portion 12 can be connected to or detached from the outer shell portion 11. When the end cap portion 12 is connected to the outer shell portion 11, a receiving space 10a is formed between the end cap portion 12 and the outer shell portion 11. This allows the inner sidewall of the end cap portion 12 and the inner sidewall of the outer shell portion 11 to serve as the inner sidewall of the receiving space 10a, thereby facilitating the cooperation between the end cap portion 12 and the outer shell portion 11 to restrict the position of the rotating shaft 20, the motor stator 40, and the motor mover 50. When the end cap portion 12 is detached from the outer shell portion 11, the rotating shaft 20, the motor stator 40, and the motor mover 50 can be disassembled, improving the ease of replacement of the rotating shaft 20, the motor stator 40, and the motor mover 50. The encoder stator 62 is mounted on the end cover portion 12 so that the encoder stator 62 is fixed to the outside of the end cover portion 12, thereby facilitating the exposure of the encoder 60 to the outside of the housing 10. Optionally, the housing portion 11 and the end cover portion 12 are detachably connected by bolts.

[0049] Please refer to Figures 1 to 5. In this embodiment of the application, a mounting seat 211 is provided between the encoder mover 61 and the first rotating part 21. The mounting seat 211 is sleeved on the first rotating part 21 so that the mounting seat 211 is fixed relative to the first rotating part 21. The mounting seat 211 supports the encoder mover 61 so that the encoder mover 61 can be connected relative to the first rotating part 21 through the mounting seat 211.

[0050] Please refer to Figures 1 to 5. In this embodiment of the application, the mounting base 211 is arranged in a ring shape, and the axis of the mounting base 211 coincides with the axis of the first rotating part 21, so that the force of the encoder mover 61 on the mounting base 211 can be evenly distributed on the circumference of the first rotating part 21. At the same time, it helps to improve the accuracy and stability of the encoder mover 61 during rotation.

[0051] Please refer to Figures 1-5. In this embodiment of the application, the bearing 30 includes a first bearing 31 and a second bearing 32. The first bearing 31 is located in the accommodating space 10a, and the second bearing 32 is sleeved on the end cover 12. The first bearing 31 and the second bearing 32 act on different positions of the rotating shaft 20 so that the rotating shaft 20 is stably constrained in different directions, avoiding deformation of the rotating shaft 20 during rotation. The smoothness of rotation of the rotating shaft 20 is further improved by arranging the first bearing 31 and the second bearing 32.

[0052] Please refer to Figures 1 to 5. In this embodiment of the application, the frameless torque motor test assembly 100 further includes a pressure ring 70. The pressure ring 70 is connected to the outer shell 11 and presses against the first bearing 31 so that the pressure ring 70 and the outer shell 11 can cooperate to limit the vertical position of the first bearing 31, ensuring the positional accuracy of the first bearing 31 and preventing the first bearing 31 from deviating from its position.

[0053] Please refer to Figures 1 to 5. In this embodiment of the application, the motor mover 50 is located inside the motor stator 40, and there is a gap between the motor mover 50 and the motor stator 40 so that the motor mover 50 can rotate relative to the motor stator 40 through the gap space, thereby improving the smoothness of the rotation of the motor mover 50.

[0054] Please refer to Figures 1 to 5. In this embodiment of the application, the motor stator 40 is fixedly connected to the housing 11, which ensures the positional accuracy of the motor stator 40 relative to the housing 11 and avoids positional deviation of the motor stator 40.

[0055] Please refer to Figures 1-5. In this embodiment, the motor mover 50 is detachably connected to the rotating shaft 20, so that the motor mover 50 can be connected to or disconnected from the rotating shaft 20, which improves the convenience of replacing the motor mover 50. The motor mover 50 and the motor stator 40 are protected by the housing 10, which avoids the motor mover 50 and the motor stator 40 from being directly impacted by external objects, and extends the service life of the motor mover 50 and the motor stator 40.
