KOLLMORGEN SBL4-0260-2-24
Product Classification: Brushless DC Servo Motor — SBL4 Frameless Torque Motor Series
Product Introduction:
The SBL4-0260-2-24 is a frameless brushless torque servo motor designed for direct-drive applications requiring high torque density in a compact form factor. It eliminates the need for a gearbox by providing torque directly at the load, reducing backlash and improving system responsiveness.

Functional Features:
- Frameless design — stator and rotor supplied separately for direct OEM integration
- Zero-backlash direct drive — no gearbox required
- High torque-to-inertia ratio — optimized for dynamic motion control
- Low cogging torque — smooth low-speed operation
- Hall sensor feedback (optional encoder configuration available)
- Compact axial length — fits tight envelope constraints
Applicable Industries:
- Semiconductor wafer handling equipment
- Medical imaging (CT/MRI gantry drives)
- Robotics (joint actuators, collaborative robots)
- Aerospace gimbal systems
- Optical scanner and camera positioning
Model Series: SBL4 — Frameless Torque Motor Family
Installation Requirements:
- Stator must be press-fit or bonded into customer housing
- Rotor must be precision-balanced and mounted on customer shaft
- Alignment tolerance: < 0.02 mm radial runout
- Thermal interface material required between stator and housing
- Connector must be sealed against customer IP requirements
Usage Notes:
- Do not exceed continuous torque rating without derating curve validation
- Operate within 48 VDC ±10% supply range
- Ensure adequate heat sinking — thermal resistance dictates maximum continuous duty
- Do not disassemble rotor — permanent magnets are brittle and sensitive to shock
