18) steps per revolution. Gear boxes are mounted directly on the motor; the center gear rests directly on the motor shaft and replaces the input shaft on the gear box. With the motors’ rigid structure and small amount of mass, high-performance control loops can be created for dynamic applications, even in tight spaces. A choice of gear boxes is available: the 8GM30 economy series, 8GM40 single- and 2-stage standard gear boxes and 8GM50 reinforced gear boxes with bearings optimized for radial and axial forces for mechanical compatibility with Wittenstein products.
