At 6.2 kg with 63 mm centre distance, it delivers up to 167 Nm output torque &#8211; enough for multi-lane conveyor drives, construction hoist mechanisms, and heavy-duty packaging machinery that smaller frames simply cannot handle. The NMRV063 accepts IEC motor frames from 56 to 90, covering input powers up to 1.1 kW &#8211; adding frame 90 support that the NMRV050 does not offer. A unique five-flange option set including FA, FB, FC, FD, and FE provides the widest mounting flexibility in the entire NMRV range. Output shaft is &Oslash;25 mm standard with optional &Oslash;28 mm for applications requiring heavier shaft load capacity. For extreme ratios, the NMRV063 pairs with NMRV130 as output stage reaching 5000:1 in double-stage configurations with up to 2430 Nm output torque.<\/p>\n<p><img decoding=\"async\"
