The rotor machining process for electric motors consists of several modules

1. For the automatic feeding operation of the hoist, the operator need only load the material; the chain plate will hang and lift the rolled stock for output.

2. Rough-turn the outer circumference of the rotor with chamfering, then proceed with automatic feeding and unloading rotation.

3. Flatten protruding points on water nozzle ends of rotor; press both sides into a flat plane to suppress protrusions. Deburr internal bore burrs and flashes using reamers for boring and reaming. After boring, transfer for unloading.

4. For rotor-shaft riveting on the press machine, the operator only feeds material. Automatic shaft insertion, automatic rotor loading, automatic shaft pressing and riveting, automatic unloading.

5. Precision turning of the rotor's outer circumference employs either a servo motor for feed and cutting on dual axes, or a hydraulic system for feed and cutting. The rotor's outer surface finish must exhibit no deep striations. Loading, unloading, and material handling are performed by robotic arms. Single-end or double-end precision turning options are available.

6. Following machining in preceding stages, the rotor outer circumference requires polishing. Deburring and removal of residual debris from the outer surface is performed using wire brushes. Post-processing, the outer circumference is coated with a light gold-coloured rust inhibitor to prevent corrosion of the silicon steel laminations.

7. Automatic bushing insertion is achieved via vibratory bowl feeding and orientation. One method employs an automated maple leaf gripper to clamp and compress the thrust bushing, while another uses a robotic arm to push the bushing into position. The thrust bushing is then automatically retrieved by the gripper and rolled into the guide rail. Upon customer request, an automated tray placement system can be implemented, where the robotic arm places the rotors onto a template. Each template cover and motor rotor can accommodate 100 units. Fan motor rotors can be accommodated up to 50 units.
