MWU Single-Disc Clutch

The growing integration of different drive forms in drive trains hybrid technologies and the development of low-consumption drives require the activation and deactivation of diverse subassemblies.

They also require clutches with low consumption and an excellent torque to space ratio that can disengage quasi free from residual torque. Electromagnetic Pole-Face friction Clutches are ideal for activating auxiliary units in agricultural machinery, municipal vehicles, and textile machinery and for compressor drives in cooling units, laundry machinery, test rigs, and PTO drives.
