Kollmorgen M205-C21-259
Product Brief: The M205-C21-259 is a legacy configured part number for a Kollmorgen M200 Series direct-drive rotary table or frameless motor kit with a 205 mm outer diameter stator/rotor set, C21 = winding/stack option, 259 = special modification/feedback/bearing option. These are torque-motor-based rotary positioners providing zero-backlash direct coupling to the load. Modern equivalents are the Kollmorgen RBE / RMB / DD (Direct Drive Rotary) series.
Detailed content
Working Principle: A large-diameter permanent-magnet torque motor (frameless stator + rotor) directly coupled to the load (no gearbox/ballscrew), producing high torque at low speed with zero backlash. Position feedback is provided by an integral high-resolution encoder (typically optical absolute — Renishaw / Heidenhain — per option code).
Outer Diameter (Stator/Rotor): ≈ 205 mm (M205 frame)
Continuous Torque (Typical M205, C21 winding): ≈ 15 – 25 Nm (varies with stack height — verify nameplate)
Peak Torque: ≈ 45 – 75 Nm
Maximum Speed: ≈ 300 – 500 rpm (winding-dependent)
Position Feedback (Typical): Optical absolute encoder (Renishaw RESOLUTE / Heidenhain ROC/ERAper option) — 17-bit to 27-bit singleturn + multiturn
Bearings (if complete table): Integral crossed-roller or angular-contact bearings rated for specified axial/radial loads
Supply Voltage (Drive): Matched to Kollmorgen AKD or S700 drive (typically 240/480 VAC 3Φ)
Operating Temperature: 0 °C to +40 °C (table); motor element –20 °C to +55 °C
Weight (Complete Table): ≈ 8 – 12 kg (frameless kit lighter)
Compliance: CE (per base platform)
Applicable Industries: Semiconductor wafer processing (rotary index tables), aerospace component test turntables, packaging rotary dial tables, pharmaceutical rotary fillers, machine tool index tables
Installation Requirements (Complete Table): Mount on machined face perpendicular to rotation axis; align load coaxially to table axis within specified runout; connect encoder to drive feedback port; ensure air purge (if cleanroom version) is connected; follow bearing preload/run-in procedure per manual.
Usage Notes: M200 series is legacy/discontinued — replacement is RBE (Direct Drive Rotary Table) or RMB (Rotary Motor Kit) series; verify exact torque/speed/feedback from nameplate before specifying replacement drive; frameless kits require customer-supplied bearings/housing — align rotor/stator with ≤ 0.1 mm eccentricity.
