✅ Temel Özellikler ve Benzersiz Avantajlar
🔗 Sonsuz Dişli Yönlü Kuyruk Çıkış Mili — Temel Farklılaştırıcı Özellik
The defining feature of the NMRV-E110 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.
🚢 Crane-Grade IEC Flange + Position Encoder
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.
◯ Same Torque as Standard NMRV110
The NMRV-E110 delivers identical maximum output torque (9,232 N·m) to the standard NMRV110, 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

❓ Sıkça Sorulan Sorular
What is the tail output shaft on the EP-NMRV-E110 and what is it used for?
The tail output shaft on the NMRV-E110 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-E110?
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 9,232 N·m, identical to the standard NMRV110.
What encoder types are compatible with the NMRV-E110 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-E110?
The NMRV-E110 accepts the following IEC input flanges: 90B5, 90B14, 100/112B5, 100/112B14, 132B5. This covers the standard motor frame range for the 7.5 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E110 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
★★★★★
“Our NMRV-E110 crane travel drives include tail-shaft encoders that feed our crane position management system. Load positioning accuracy has improved from plus/minus 50 mm to plus/minus 8 mm since installation. Excellent product for precision crane control.”
Richard H. — Crane Engineer, Manufacturing Facility 🇦🇺 Australia (VIC)
★★★★★
“We installed the NMRV-E110 on our large chemical reactor agitator. The tail-shaft encoder feeds our DCS with real-time agitator speed data. We detected a partial gear wear event early via speed drift monitoring and replaced the unit before failure.”
Dr. Klaus W. — Chemical Process Engineer 🇩🇪 Germany
★★★★☆
“NMRV-E110 drives our port conveyor with tail-shaft speed feedback to the terminal management system. Throughput monitoring is now automated and we eliminated the manual rotation checks that previously required a site walk every two hours.”
