✅ Temel Özellikler ve Benzersiz Avantajlar
🔗 Sonsuz Dişli Yönlü Kuyruk Çıkış Mili — Temel Farklılaştırıcı Özellik
The defining feature of the NMRV-E040 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.
📈 3,118 N·m with IEC Flange + Encoder
The NMRV-E040 delivers 3,118 N·m maximum output torque with direct IEC motor flange mounting AND a tail shaft encoder output, providing the complete gearmotor-plus-encoder function in a single compact unit.
◯ Same Torque as Standard NMRV040
The NMRV-E040 delivers identical maximum output torque (3,118 N·m) to the standard NMRV040, 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.
🅆 Kodlayıcı ve Geri Besleme Hazır
Kuyruk çıkış mili, kapalı devre hareket kontrol sistemlerinde sonsuz dişli milinin hızını izleyen döner kodlayıcılar, takojeneratörler ve darbe üreteçleri için doğrudan bir bağlantı noktası sağlar ve harici kodlayıcı braketleri ve bağlantı donanımlarını ortadan kaldırır.
🚫 IP54 — Çift Conta Bütünlüğü
Hem ana çıkış deliği hem de kuyruk mili çıkışı, çift temaslı dudak contalarıyla kapatılarak, her iki mil arayüzünde de yağ sızıntısı olmadan tüm montaj yönlerinde IP54 koruma seviyesi korunmaktadır.
🏭 Uygulama Senaryoları
⚙ Conveyor Speed Synchronisation
NMRV-E040 worm gearbox for multi-drive conveyor synchronisation systems. The tail shaft mounts a pulse encoder that feeds back to a master PLC, allowing all conveyor sections to maintain matched belt speeds.
🚮 Packaging & Labelling with Feedback
Industrial worm gear reducer with tail output shaft for packaging line label applicators and capping heads where encoder-verified torque delivery prevents label misregistration.
🌿 Agricultural Controlled Seeding
Corrosion-resistant NMRV-E worm gearbox for precision seeding machinery where tail-shaft encoder feedback to a GPS-linked controller varies seed rate in real time across paddock zones.
📥 Textile Tension Control
Worm gearmotor with tail shaft for textile winding machine let-off drives where real-time winding speed feedback via the tail shaft encoder maintains precise fabric tension throughout the roll.

❓ Sıkça Sorulan Sorular
What is the tail output shaft on the EP-NMRV-E040 and what is it used for?
The tail output shaft on the NMRV-E040 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-E040?
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 3,118 N·m, identical to the standard NMRV040.
What encoder types are compatible with the NMRV-E040 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-E040?
The NMRV-E040 accepts the following IEC input flanges: 56B5, 63B14, 71B5, 71B14. This covers the standard motor frame range for the 0.55 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E040 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.
⭐ Müşteri Yorumları
★★★★★
“The NMRV-E040 drives our multi-section conveyor synchronisation system. The tail shaft encoder provides the PLC with speed reference for all eight conveyor sections and registration errors have dropped to near zero since installation.”
Marcus L. — Automation Engineer, Packaging Plant 🇦🇺 Australia (Victoria)
★★★★★
“We use the NMRV-E040 on our textile winding tension control system. The tail-shaft tachogenerator gives us real-time winding speed data and our fabric defect rate has fallen by 22% since switching from open-loop drives.”
Elif T. — Production Manager, Textile Manufacturer 🇹🇷 Turkey
★★★★☆
“Fitted NMRV-E040 units on our labelling machine indexing drives. The tail shaft encoder confirmed our line speed to within 0.1% and eliminated occasional label skip errors that had plagued the previous open-loop arrangement.”
James O. — Line Engineer, Label Manufacturer 🇦🇺 Australia (QLD)
