Working Operational Principle
Three-phase sinusoidal PWM drive current from paired AKD servo drive generates rotating electromagnetic field inside stator assembly. High-strength permanent magnet rotor synchronously follows rotating field to produce continuous high torque output. EnDat 2.2 absolute encoder transmits multi-turn absolute rotor position data to drive unit upon power-up, removing mandatory homing cycle. Integrated electromagnetic holding brake mechanically locks motor shaft upon 24VDC brake power supply cutoff to prevent load free fall during machine power failure or emergency stop conditions.
Key Competitive Advantages
- High-stack core architecture delivers maximum torque density within standard 100mm flange mounting dimensions
- IP67 full enclosure eliminates external protective housing requirement for wet/dusty factory production environments
- Built-in multi-turn absolute encoder reduces machine startup cycle time by eliminating homing movement
- Integrated holding brake assembly removes separate brake mechanical component and mounting hardware costs
- Ultra-low torque ripple enables micron-level precision positioning under heavy continuous load conditions
Applicable Industrial Market Segments
CNC metal cutting machine feed axes, automated palletizing robots, heavy-duty packaging sealing equipment, injection molding machine positioning axes, semi-washdown food processing machinery, automated welding fixture positioning, large optical inspection motion stages.
Strict Installation Technical Specifications
- Flange mounting surface flatness tolerance ≤0.02mm; four mounting bolts torqued evenly to 4.2 N·m
