Kollmorgen B-606-B-A9-B3-203

Product Introduction:​ The Goldline EB series are low-inertia, rare-earth magnet synchronous servo motors designed for high dynamic performance. The EB-606 frame is a mid-size NEMA 20 / IEC equivalent motor typically used with Kollmorgen ServoStar CD/S300/S600 drives. The suffix “-B” denotes stack length B (medium torque), and the option codes indicate resolver feedback, special connector/MS bayonet, and possibly a rear shaft or thermostat per customer specification.

Detailed content

  • Typical Performance Data (EB-606-B):
    • Rated Voltage (Line-Line):​ 230 V AC RMS (typical for 230 V class Goldline B)
    • Continuous (Stall) Torque @ 40 °C:​ ≈ 3.03 N·m (27 lb-in)
    • Peak Torque:​ ≈ 9.7 N·m (86 lb-in)
    • Continuous Current:​ ≈ 5.4 A RMS
    • Peak Current:​ ≈ 16.0 A RMS
    • Rated / Max Speed:​ Typically 3000–6000 RPM (depends on winding; EB-606-B often 3000 RPM rated, 6000 RPM max)
    • Torque Constant (Kt):​ ≈ 0.56 N·m/A RMS
    • Back-EMF Constant (Ke):​ ≈ 37 V/kRPM (RMS line-line)
    • Rotor Inertia:​ ≈ 0.003 kg·m²
    • Thermal Time Constant:​ ≈ 16 min
    • Insulation Class:​ H (180 °C)
    • Protection:​ IP65 (with shaft seal option), IP54 (standard)
    • Feedback:​ 2-pole or multi-pole brushless resolver (standard on EB series)
    • Brake Option:​ None unless specified; 24 V DC or 90 V DC fail-safe brake available optionally
    • Connector:​ MS-type bayonet or flying leads depending on option code
  • Structure & Material:​ Neodymium-iron-boron (NdFeB) permanent magnet rotor; laminated stator core; aluminum housing with finned surface for convection cooling; stainless steel shaft with keyway (or smooth shaft per option); ball bearings rated for high-speed operation.
  • Working Principle:​ Three-phase sinusoidal PWM current from the servo drive creates a rotating magnetic field that interacts with the PM rotor; resolver provides rotor position feedback for commutation and closed-loop control.
  • Applications:​ High-speed indexing, pick-and-place robots, semiconductor handlers, packaging equipment, printing rollers—anywhere rapid acceleration/deceleration and low inertia are required.
  • Installation & Cautions:​ Mount via standard 4× bolt flange pattern; align coupling to avoid side loads > radial spec; ground motor frame to drive earth; do not disconnect feedback wires while powered; thermostat (if present) should be wired to drive for overtemperature protection.
