[0002] The motor's rotor shaft, also known as the axis of rotation, is the core component of the motor's rotor. It's typically made of high-strength materials like steel or alloys to ensure sufficient mechanical strength and magnetic conductivity. As the rotor's support and center of rotation, its structural design must consider supporting the rotor's weight, transmitting torque, and maintaining rotor balance. The motor's rotor shaft transmits power through rotation, converting the motor's electromagnetic energy into mechanical energy, thereby driving the load. As one of the primary components for transmitting power in a motor, the motor's rotor shaft also supports the rotor, enabling stable rotation within the stator. The weight of the rotor and the force generated during operation are borne by the rotor shaft. The design and manufacturing accuracy of the motor rotor shaft have a great influence on the balance of the rotor. If the rotor shaft is unbalanced, it will cause vibration and noise when the rotor is running, affecting the performance and life of the motor. Therefore, the motor rotor shaft needs to ensure the balance of the rotor. During motor production, the diameter of each part of the rotor shaft must be within the allowable error range. Existing rotor shaft inspections are mostly measured with calipers. It is not convenient to measure the rotor shaft manually by hand.

[0018] Among them, the internal rotation of the sliding inner plate 10 is connected with a bidirectional screw rod 16, and the outer side of the bidirectional screw rod 16 is symmetrically threaded with an adjusting slider 15.

[0023] Specifically, when inspecting the diameter of the rotor shaft, the rotor shaft is placed in the side groove 3 on one side of the fixed inner plate 2, the rotor shaft is located between the two shaft clamping blocks 8, powered by an external power supply, and the No. 1 hydraulic cylinder 7 is started through the control panel 22.
