Features:
High‑speed 6000 rpm capability; low inertia for rapid acceleration; sinusoidal winding for smooth torque; resolver for accurate commutation.
Application Scenarios:
High‑speed spindle‑like axes, robotics, packaging machinery, transfer lines, and other precision motion‑control systems.
Construction & Material:
Neodymium‑iron‑boron (NdFeB) permanent‑magnet rotor; aluminum housing; resolver at rear.
Working Principle:
Brushless synchronous operation: the drive supplies three‑phase sinusoidal currents whose frequency matches the commanded speed; resolver provides rotor angle for precise current commutation.
Installation Requirements:
Flange‑mount on 75 mm square flange; align shaft with flexible coupling; use mating connectors for power and resolver; ensure 400 V‑class drive with appropriate DC‑bus voltage (up to 600 V DC).
Precautions:
-
Provide adequate cooling; do not exceed insulation temperature limits.
-
Use shielded resolver cable, separated from power lines.
-
Confirm drive compatibility (e.g., Kollmorgen Servostar, Digifas, or third‑party 400 V‑class servo amp).
-
Avoid axial load beyond specification (no keyway → rely on coupling for torque transmission).
