[0002] The rotor core is usually composed of several rotor punchings stacked together. The quality of its assembly plays a vital role in the overall performance indicators of the motor. It is widely used in energy-saving motors such as servo motors. During the production process of the rotor core, axial extrusion is required to make the rotor punchings fit fully, and subsequent inspection is required. At present, the inspection of the rotor core includes appearance and inner hole go / no-go gauges.
