-
Shaft: ⌀24 mm with keyway (DIN 6885), shaft length ~50 mm
-
Motor Length (w/o connector): approx. 198 mm (body) / overall ~221 mm
-
Holding Brake: None (“N” in code)
-
Feedback: 2-pole resolver (accuracy ±8 arc-min), mounted inside rear cap
-
Connectors: 2 × M23 angular SpeedTec Ready connectors (power + feedback), rotatable 4×90°
-
Thermal Sensor: PTC thermistor (KTY84 or equivalent) in winding
-
Mass: approx. 9.0 kg
-
-
Protection: Standard IP54 (shaft seal option upgrades to IP65), Insulation Class F/H (155 °C / 180 °C)
-
Mounting: Flange mount, IM B5 (face mount). Tapped holes in flange for through-bolts or foot mounts optional.
-
Application Areas: Packaging machines, printing presses, CNC rotary axes, material handling, robotics requiring high continuous torque.
-
Installation Notes: Align coupling to avoid radial load on shaft bearings. Connect shield of power cable to PE terminal in drive. Verify motor phase order (U-V-W) if manual connection; resolver wired per pinout. Allow free convection — leave ≥50 mm clearance at non-drive end.
