Linear Motors

Buyer Decision Criteria

• Thrust target, air gap, pole pitch, stroke, and ripple tolerance.
• Thermal load from continuous duty and nearby coil heating.
• Carrier stiffness, mounting datums, and cleanroom material constraints.
• Validation method for force, field, and module-to-module repeatability.

Factory Support Scope

• Linear array module production with matched pole pitch and field mapping.
• CNC carriers for precision stage and semiconductor equipment integration.
• High-temperature grade review for sustained force operation.
• Prototype modules with inspection reports for customer force testing.

RFQ Preparation Checklist

1. Peak and continuous thrust force requirements
2. Stroke length, air gap, pole pitch, and moving mass
3. Duty cycle, coil heat assumptions, and allowed temperature rise
4. Force ripple tolerance and field mapping acceptance method

Risk and Mitigation

• Thermal demagnetization: High-UH/EH grade NdFeB.
• Mismatch between coil model and supplied magnet track: Confirm air gap, pole pitch, and field map height before prototype build.
• Long-axis installation errors: Ship matched, labeled sections with joint and datum inspection notes.

Validation Deliverables

• Gap field map and pitch inspection.
• Carrier critical dimension report.
• Material grade and coating confirmation.
• Prototype acceptance checklist for production freeze.

RFQ to Delivery Flow

1. Send force target, stroke, gap, pole pitch, duty cycle, and installation drawing.
2. We review magnet grade, pitch, carrier, and mapping requirements.
3. Prototype results set the production inspection baseline.
4. Repeat orders follow matched module labeling and packaging controls.
