Kollmorgen SM45-M3000NSNP

Product Introduction:
The Kollmorgen SM45-M3000NSNP belongs to the discontinued 6SM/SM iron-core synchronous servo motor platform, later conceptually replaced by the AKM series. It is a permanent-magnet brushless rotary servo motor designed for high-dynamic CNC, robotics, and industrial automation axes. The “M3000” suffix denotes a 3000 rpm rated wind, while “NSNP” identifies a specific shaft, seal, connector, and feedback configuration from Kollmorgen’s legacy naming system.

  • Rated Speed:​ 3000 rpm
  • Rated Power:​ approx. 0.5 kW to 3.0 kW depending on stack length (SM45 frame mid-size)
  • Rated Torque:​ approx. 1.7 Nm (low-stack) up to 9.55 Nm (high-stack)
  • Voltage Class:​ low-voltage servo winding, typically 75 VDC bus or 120/240 VAC drive-compatible
  • Feedback:​ incremental encoder (variant-dependent), resolver optional
  • Protection Class:​ IP64 or IP65

  • Weight:​ approx. 13 kg for full-stack version
  • Mounting:​ metric flange, through-bolts, concentricity-critical alignment
Functional Characteristics:
  • Low rotor inertia for fast acceleration
  • Neodymium magnet rotor with low cogging
  • Compatible with Kollmorgen S200/S300 drives via resolver or incremental encoder
  • Robust bearings rated >20,000 h under nominal load
Application Scenarios:
  • CNC spindle辅助 axes
  • Packaging machine indexers
  • Legacy semiconductor handling retrofits
  • Press feed rolls and converting machinery
Structure & Materials:
  • Laminated silicon-steel stator stack
  • Sintered NdFeB rotor magnets
  • Die-cast aluminum housing with black enamel finish
  • Steel shaft with keyway or smooth variant
  • FKM shaft seal, optional drain holes for vertical mount
Installation Requirements:
  • Mount on flat, clean, degreased surface
  • Align motor shaft to load coupling within <0.05 mm TIR
  • Use torque-rated bolts (typically M6/M8 depending on flange)
  • Separate power and feedback cables; shield drained to cabinet ground
  • Drive must support 3000 rpm wind and matching encoder resolution
Usage Notes:
  • Do not clean with acidic or high-pH solvents
  • Vertical shaft applications require external safety brake despite optional holding brake
  • Verify encoder commutation offset during first commissioning
