Kollmorgen TTRB-4501-1002-B

Product Introduction:
The TTRB-4501-1002-B is a Kollmorgen rotary transducer assembly combining a precision resolver and mechanical hub for torque/angle measurement or redundant feedback on large servo axes. Used mainly as a replacement feedback element on BMH/AXH motors or as a coupling-mounted sensor.

Detailed content

Technical Specifications:
  • Type: brushless resolver + mechanical flange hub
  • Body diameter: 45 mm
  • Shaft pass-through: 10 mm
  • Resolution: 2-pole resolver, 1000 P/R equivalent
  • Output: sine/cosine analog, 0–7 Vpp
  • Accuracy: ±10 arcmin
  • Max speed: 6000 RPM
  • Connection: 7-pin circular connector
  • Code “-B”: B-side wiring, second source variant
Features:
  • Immune to EMI, dust, oil
  • No wear parts, no battery
  • Direct bolt-on to motor rear
Working Principle:
Rotor transformer winding excited by 5 kHz carrier; stator picks up amplitude-modulated sine/cosine; external RDC converts to digital angle.
Materials & Construction:
  • Stainless hub, glass-filled nylon resolver shell
  • Sealed bearings
Installation Requirements:
  • Concentricity < 0.02 mm
  • Avoid magnetic materials near body
  • Shielded cable, separate from power
Precautions:
  • Never apply DC to excitation winding
  • Alignment error causes null shift
  • Not a standalone torque sensor—needs RDC card
