maxon DCX motors feature unrivaled power density (torque per volume) and absolutely quiet running. The robust engineering, combined with the globally patented ironless winding, makes the DCX motors a highly dynamic drive for almost every application scenario.

The DCX 12 S is available as a small drive with preloaded ball bearings or sintered bearings. The optional spark suppression (CLL) makes this DC motor with precious metal brushes a real long-distance runner.
