✅ Fonctionnalités principales et avantages uniques
🔗 Arbre de sortie à vis sans fin — L'élément clé de différenciation
The defining feature of the NMRV-E063 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.
🖼 Print-Line Precision
The NMRV-E063 is particularly valued in printing and packaging lines where the IEC flange motor drives the print roll while the tail shaft encoder provides the master speed reference signal for digital register control.
◯ Same Torque as Standard NMRV063
The NMRV-E063 delivers identical maximum output torque (5,595 N·m) to the standard NMRV063, 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.
Encodeur et retour d'information prêts
L'arbre de sortie arrière fournit un point de connexion directe pour les codeurs rotatifs, les tachymètres et les générateurs d'impulsions qui surveillent la vitesse de l'arbre à vis sans fin dans les systèmes de contrôle de mouvement en boucle fermée, éliminant ainsi les supports de codeur externes et les éléments de couplage.
🚫 IP54 — Intégrité à double joint
L'alésage de sortie principal et la sortie de l'arbre de queue sont tous deux étanches grâce à des joints à lèvres à double contact, maintenant une protection IP54 dans toutes les orientations de montage sans suintement d'huile au niveau de l'interface de l'arbre.

🌿 Precision Agricultural Seeding
Medium-duty worm gear reducer with tail output shaft for precision agricultural seeding and fertiliser application equipment where GPS-linked controllers require accurate shaft speed feedback for variable-rate application.
⚙ Automation Line Synchronisation
Industrial worm gearmotor with tail shaft for central-line-shaft automation systems where the tail-mounted tachogenerator provides the supervisory controller with a line-speed reference signal.
💧 Water & Wastewater Monitoring
Corrosion-resistant NMRV-E worm gear reducer with tail output shaft for instrumented valve actuator drives in water treatment plants, where the tail shaft pulse counter confirms valve position remotely.

❓ Foire aux questions
What is the tail output shaft on the EP-NMRV-E063 and what is it used for?
The tail output shaft on the NMRV-E063 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-E063?
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 5,595 N·m, identical to the standard NMRV063.
What encoder types are compatible with the NMRV-E063 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-E063?
The NMRV-E063 accepts the following IEC input flanges: 71B5, 71B14, 80B5, 80B14, 90B14. This covers the standard motor frame range for the 2.2 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E063 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.

★★★★★
“Our precision conveyor line uses eight NMRV-E063 units. The tail shaft encoders synchronise all eight drives via our central motion controller. Line synchronisation is perfect and we have logged zero registration errors across six months of production.”
Lars H. — Systems Engineer, Automation OEM 🇸🇪 Sweden
★★★★★
“We use the NMRV-E063 on our grain auger with real-time rotation monitoring. The tail-shaft sensor triggers a bin-full alarm when rotation speed drops below a threshold. This simple feature has prevented two auger jam incidents already.”
Darren K. — Farm Manager, Grain Storage 🇦🇺 Australia (WA)
★★★★☆
“The NMRV-E063 drives our packaging line with tail-shaft encoder feedback to our servo master controller. Product count accuracy improved to 100% and we eliminated all the over-run stops that wasted packaging material.”
