Product Short Description
Product Name: SEW-EURODRIVE DFS56L/TF/RH1M/KK — Permanent Magnet Synchronous Servo Motor
Product Overview: The DFS56L/TF/RH1M/KK is a compact, high dynamic performance permanent magnet synchronous servo motor from SEW-EURODRIVE’s DFS series. The code breakdown: DFS56L = servo motor frame size 56, long stack (higher torque); TF = PTC thermistor winding temperature protection; RH1M = 1-speed resolver with medium resolution, M16×1.5 connector; KK = standard power + signal connector kit.

Key Features: Low cogging and high efficiency; rugged IP65 construction (dust-tight, splash-proof); PTC thermistor for winding over-temperature protection; resolver feedback for robust position sensing in harsh environments; long stack design for higher torque density.
Application Scenarios: High-dynamic precision motion control in industrial automation, robotics, packaging machinery, machine tools, handling systems, textile machinery tension control, and CNC auxiliary feed axes.
Installation & Usage Notes: Mount on flat, rigid surface with all flange bolts securely tightened. Avoid radial/axial overload; use flexible couplings. Allow ≥100 mm clearance for cooling and cable bending. Use shielded cables for power and feedback (EMC compliance). Keep away from magnetic media due to permanent magnets. Do not exceed rated voltage, current, or torque. Disconnect all power before mounting, wiring, or servicing.
