Core Features
- 23 Nm continuous standstill / 88 Nm theoretical peak
- Liquid-cooled housing for sustained stall without derating
- HSF digital feedback (relative, homing required on power-up)
- 22 Nm fail-safe holding brake included
- IP65 + shaft seal for washdown / coolant-splash zones
- Right-exit power connector simplifies cabinet routing
- Lifetime-greased bearings, high radial load capacity (direct pulley/pinion mount)
- Thermal sensors warn the drive before winding damage
Typical Applications
- CNC rotary tables, tool changers, B-axis heads
- Press feed / knee drives, liquid-cooled spindles aux axes
- Packaging gantries and vertical lift axes needing brake hold
- Printing / paper handling rollers with frequent stall
- Robotics joints where housing coolant loop already exists
- Retrofit of legacy Indramat MHD axes in metal-cutting cells
