Kollmorgen Frameless servo motors are designed to be embedded directly into the machine, using the machine’s own shaft and bearings to support the rotor.

  • Compact footprint
  • Industry-leading torque density 
  • Efficient thermal performance 
  • Broad range of sizes 
  • Ready to scale from prototype to high-quality manufacturing 
Kollmorgen frameless motors.

Kollmorgen TBM2G

High-performance torque in the lightest, most compact electromagnetics package, with 63 standard configurations for applications up to 48 VDC.

HIGH-PERFORMANCE TORQUE IN COMPACT PACKAGE

  • Torquer (pancake) form factor: shorter axial length in relation to diameter 
  • •Maximum torque density, taking advantage of the D2L rule 
  • Designed to perform exceptionally well at 155C or even at reduced maximum winding temp to suit compact application designs
  • The industry’s broadest range of configurations: 
    • 7 diameters: 50 –115 mm 
    • 3 stack lengths: 8, 13, 26 mm 
    • 3 standard winding variations
    • Thermal and commutation sensor options
  • Large thru-bore 
  • Manufacturable in high volumes with short lead times
