✅ Caratteristiche principali e vantaggi esclusivi

🔗 Albero di uscita posteriore a vite senza fine: l'elemento distintivo fondamentale

The defining feature of the NMRV-E130 is its additional tail output shaft that extends in the same direction as the worm shaft axis. This second output enables simultaneous drive of two independent loads from a single gearbox — a primary application drive via the main output bore and a secondary auxiliary drive (encoder, tachometer, small pump, or fan) via the tail shaft.

📥 11 kW IEC + Extra-Large Tail Shaft

The NMRV-E130 delivers 12,076 N·m with direct IEC 132B5 motor flange mounting plus a 45 mm tail shaft for high-resolution encoder feedback, covering the most demanding instrumented heavy-industrial drive requirements.

◯ Same Torque as Standard NMRV130

The NMRV-E130 delivers identical maximum output torque (12,076 N·m) to the standard NMRV130, confirming that the tail shaft adds zero performance penalty on the main output. The tail shaft is driven directly off the worm shaft end, not the output stage.

🅆 Codificatore e feedback pronti

L'albero di uscita posteriore fornisce un punto di connessione diretto per encoder rotativi, tachigeneratori e generatori di impulsi che monitorano la velocità dell'albero a vite senza fine nei sistemi di controllo del movimento a circuito chiuso, eliminando staffe per encoder esterne e componenti di accoppiamento.

🚫 IP54 — Integrità a doppia guarnizione

Sia l'alesaggio di uscita principale che l'uscita dell'albero di coda sono sigillati con guarnizioni a labbro a doppio contatto, mantenendo la protezione IP54 in tutte le configurazioni di montaggio senza perdite d'olio in corrispondenza delle interfacce dell'albero.

❓ Domande frequenti

What is the tail output shaft on the EP-NMRV-E130 and what is it used for?

The tail output shaft on the NMRV-E130 is a secondary shaft extending in the worm-direction axis (co-axial with the worm shaft, opposite end). It is used to mount rotary encoders, tachogenerators, or pulse generators for speed/position feedback, or to drive a small auxiliary load such as a lubrication pump, cooling fan, or pilot valve simultaneously with the main output drive.

Does the tail shaft affect the main output torque of the NMRV-E130?

No. The tail shaft is driven directly off the worm shaft end and carries only the small torque required for the encoder or auxiliary device. The main output bore delivers the full rated 12,076 N·m, identical to the standard NMRV130.

What encoder types are compatible with the NMRV-E130 tail output shaft?

The tail shaft is a standard keyed shaft accepting any incremental or absolute rotary encoder with the matching bore size. Common options include 5–24V incremental encoders (100–10,000 PPR), SSI absolute encoders, and resolver-type feedback devices. Confirm the encoder bore and key dimensions with the encoder supplier before ordering.

Which IEC motor flanges are available for the EP-NMRV-E130?

The NMRV-E130 accepts the following IEC input flanges: 90B5, 90B14, 100/112B5, 100/112B14, 132B5. This covers the standard motor frame range for the 11 kW power class. Servo and stepper motor adaptor plates available on request.

Can the NMRV-E130 tail shaft be used to drive a secondary load simultaneously?

Yes, provided the secondary load torque on the tail shaft does not exceed the worm shaft’s additional torque capacity. For light-duty secondary loads such as small lubrication pumps (below 0.05 kW) or pilot valves, the tail shaft can be used simultaneously without affecting main output performance. Consult our engineering team for secondary loads above 0.05 kW.

⭐ Recensioni dei clienti

★★★★★

“We use the NMRV-E130 on our gantry crane hoist drum drive. The tail-shaft encoder provides load position feedback to our crane control PLC with 5 mm positioning resolution. The integrated encoder mount saved us two weeks of custom bracket fabrication time.”

Craig S. — Crane Engineer, Heavy Industry 🇦🇺 Australia (SA)

★★★★★

“Our large primary clarifier rake uses an NMRV-E130 with a tail-shaft pulse counter integrated into our water authority SCADA. We now monitor rake rotation remotely across all eight clarifiers from a single control room screen.”

Niamh F. — Asset Manager, City Water Services 🇮🇪 Ireland

★★★★☆

“The NMRV-E130 drives our port stacker-reclaimer slewing mechanism. The tail-shaft encoder feeds our terminal management system with real-time slewing position data. Installation was straightforward and position accuracy is excellent.”
