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;\">&#128674; Crane-Grade IEC Flange + Position Encoder<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">At 7.5 kW with IEC 132B5 flange compatibility, the NMRV-E110 is purpose-built for instrumented crane travel drives where both direct motor mounting and precise position feedback are required simultaneously.<\/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 NMRV110<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">The NMRV-E110 delivers identical maximum output torque (9,232 N&middot;m) to the standard NMRV110, confirming that the tail shaft adds zero performance penalty on the main output.
