With a solid &Oslash;9j6 input shaft instead of an IEC motor flange, the NRV025 accepts any motor type via standard shaft coupling &#8211; servo motors, stepper motors, DC brushless, hydraulic motors, and even combustion engine PTO drives. This universal motor compatibility is the defining advantage of the NRV series over the IEC-flange-only NMRV series. At approx. 1 kg with 25 mm centre distance and &Oslash;11g6 output shaft, it delivers up to 14 Nm output torque across ratios 5-60:1. The die-cast aluminium alloy housing provides corrosion resistance and thermal efficiency superior to cast iron while saving 30-50% in weight. Purpose-designed for laboratory sample carousels, automated dispensing valves, and micro-positioning systems where the solid input shaft enables direct servo and stepper motor coupling.<\/p>\n<p><img
