extends in the same direction as the worm shaft axis. This second output enables simultaneous drive of two independent loads from a single gearbox &mdash; a primary application drive via the main output bore and a secondary auxiliary drive (encoder, tachometer, small pump, or fan) via the tail shaft.<\/p>\n<\/div>\n<div style=\"width:100%;max-width:400px;box-sizing:border-box;background:#fff;border:1px solid #D8DCE3;border-top:4px solid #E8A020;border-radius:6px;padding:3%;\">\n<h3 style=\"color:#1B3F6E;font-size:clamp(15px,2vw,18px);margin-top:0;\">&#127302; VFD + Encoder in One Unit<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">The NMRV-E050 works seamlessly with VFD-driven IEC motors while the tail shaft simultaneously provides speed\/position feedback, creating a closed-loop VFD-gearbox-encoder assembly without external sensor brackets.<\/p>\n<\/div>\n<div style=\"width:100%;max-width:400px;box-sizing:border-box;background:#fff;border:1px solid #D8DCE3;border-top:4px solid #2E9E6B;border-radius:6px;padding:3%;\">\n<h3 style=\"color:#1B3F6E;font-size:clamp(15px,2vw,18px);margin-top:0;\">&#9711; Same Torque as Standard NMRV050<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">The NMRV-E050 delivers identical maximum output torque (4,280 N&middot;m) to the standard NMRV050, confirming that the tail shaft adds zero performance penalty on the main output.
