Working Principle:
Permanent magnet synchronous motor (PMSM) with sinusoidal back-EMF. The stator windings are driven by a servo drive (e.g., AKD series) using field-oriented control (FOC). The rotor contains high-energy rare-earth permanent magnets (NdFeB). The servo drive commutates the stator current in synchronism with rotor position (from encoder/resolver feedback) to produce precise torque and speed control.

Key Advantages:

• High torque density — delivers maximum torque in a compact footprint
• Low cogging torque — smooth motion at low speeds
• Wide speed range — constant torque up to base speed, field weakening beyond
• High efficiency — typically >90% at rated operating point
• Low maintenance — sealed bearings, no brushes

Applicable Industries:

• CNC machining centers
• Packaging machinery
• Printing presses
• Robotics (articulated arms, SCARA)
• Semiconductor equipment
• Medical devices

Installation Requirements:

• Mount on rigid, vibration-damped surface
• Align shaft coupling within 0.05 mm TIR
• Use flexible coupling to absorb misalignment (max 0.1 mm angular, 0.15 mm axial)
• Torque mounting bolts to manufacturer specification (typically 6–12 Nm for M6 bolts)
• Ensure adequate ventilation or forced air cooling for continuous operation

Usage Notes:

• Do not exceed rated voltage or current
• Ensure proper grounding of motor frame and drive
• Use only Kollmorgen-approved cables and connectors
• Avoid exposure to corrosive chemicals without protective coating
• Store in dry environment; use desiccant if stored long-term
