[0002] The flange-adjustable servo motor has high precision, high dynamic response and flexible adjustment. The flange-adjustable servo motor can optimize the dynamic response of the system by adjusting the moment of inertia to achieve more accurate and reliable position and speed control.

[0003] Among the existing published technical documents, the Chinese patent publication number CN215817741U discloses a 60 flange moment of inertia adjustable servo motor, which has a cooling fan installed through one end of the motor housing, and multiple air inlet frames are fixed through the outer end surface of the motor housing, so as to absorb excess vibration, maintain stability, and ensure heat dissipation, thereby ensuring the installation stability and heat dissipation effectiveness of the servo motor. However, the servo motor has the following defects.

[0004] Although the servo motor can control the rotation angle during the process of adjustable flange moment of inertia, when it rotates to the specified angle, once the equipment is damaged, it will cause the brick to over-rotate, causing damage to the equipment due to excessive rotation, making it difficult to accurately limit the angle, and thus the servo motor angle is difficult to use. Therefore, a servo motor with adjustable flange moment of inertia is needed. Utility Model Content
