Rotor assembly is a complex process requiring a series of equipment. Whether automated or semi-automated, each has specific requirements. So, what are the requirements for automated equipment in rotor assembly? How do you select and evaluate equipment? Vacuz will briefly introduce this below!

I. Equipment Stability and Core Configuration

1. Core Component Quality

The equipment must use high-precision core components, such as precision ball screws, guide rails, cylinders, servo motors, and drive systems. These components directly affect the stability of the equipment’s operation. Insufficient configuration may lead to vibration, positioning deviations, or speed fluctuations, thus affecting the rotor assembly accuracy (such as air gap and concentricity).

For example, the servo motor must have high response speed and low inertia characteristics to ensure the dynamic accuracy of processes such as rotor magnet insertion and shaft pressing.

2. Mechanical Structure Rigidity

The frame must have high rigidity to reduce the risk of deformation during long-term operation. Insufficient frame rigidity may lead to component misalignment during rotor assembly, affecting magnetic circuit symmetry or dynamic balance performance.

II. Flexibility and Compatibility

1. Multi-Model Adaptability

The equipment must support rapid model changeover to adapt to the production needs of rotors with different specifications (e.g., number of poles, diameter, shaft length). Changeover time should be controlled within 30 minutes to avoid production stoppages due to mold changes or program adjustments.

For example: modular design allows for rapid replacement of components such as magnet slots and pressure shaft tooling.

2. Process Expandability

The equipment must have reserved interfaces to support future process upgrades (e.g., adding magnetic measurement, dynamic balancing detection, etc.), extending the equipment’s service life.

III. Real-Time Monitoring and Feedback

1. Process Data Acquisition

The equipment must integrate sensors (e.g., pressure, displacement, vision systems) to collect key parameters (e.g., magnet polarity, pressing force, imbalance) in real time for processes such as magnet insertion, pressure shaft, and balancing.

For example: laser sensors can be used to detect the gap between the magnet and the slot to ensure assembly accuracy ≤0.02mm.

2. Non-conforming Product Early Warning

The system must have real-time feedback functionality. When it detects incorrect magnet polarity, excessive pressing force, or out-of-balance, it should immediately stop the machine and sound an alarm to prevent batch defects.

IV. Safety and Protection

1. Electrical Safety

The equipment must be equipped with overcurrent protection, grounding circuits, and insulation monitoring to prevent safety accidents caused by leakage or short circuits.

For example, the servo drive must have an emergency braking function, stopping movement within 0.1 seconds in the event of a sudden malfunction.

2. Mechanical Protection

Critical parts (such as pressing fixtures and rotating components) must be equipped with protective covers to prevent operators from contacting dangerous areas. Simultaneously, the equipment must be equipped with an audible and visual alarm system to indicate abnormal conditions.

Core Indicators for Equipment Selection and Evaluation:

I. Technical Capability Assessment

1. Machining Accuracy

Positioning Accuracy: The equipment’s repeatability must be ≤±0.01mm to ensure dimensional consistency in processes such as magnet insertion and pressing.

Speed ​​Stability: The no-load operating speed fluctuation rate must be ≤1% to avoid magnet misalignment or unstable pressing force due to speed changes. Test Method: Displacement error of the equipment at high speeds (e.g., 1000 RPM) is measured using a laser interferometer.

2. Dynamic Response

The equipment must have rapid start-up and shutdown capabilities, with acceleration time ≤ 0.5 seconds and deceleration time ≤ 0.3 seconds, to adapt to the rapid changeover rhythm of multi-process production.

II. Compatibility and Flexibility

1. Changeover Efficiency

Assess the time and operational complexity required for equipment changeover. For example, does changing the magnet slot tooling require tool assistance? Can program switching be completed with a single touchscreen click?

Target: Changeover time ≤ 15 minutes, minimizing production downtime.

2. Product Coverage

The equipment must support diverse requirements for rotor diameter range (e.g., Φ20-Φ200mm), number of poles (e.g., 4-24 poles), and shaft length (e.g., 50-300mm).

III. After-Sales Service and Support

1. Response Speed

The supplier must commit to responding to faults within 24 hours and arriving at the site for repair within 48 hours (major cities in China).

For example: Quickly locate software or hardware faults through remote diagnostic systems.

2. Spare Parts Supply: Assess spare parts inventory and delivery capabilities to ensure that the replacement cycle for critical components (such as servo motors and sensors) is ≤72 hours.

3. Training System:

Suppliers must provide operation, maintenance, and programming training to ensure users can independently perform routine maintenance and simple troubleshooting.
