✅ Fitur Utama & Manfaat Unik
🔗 Poros Keluaran Ekor Arah Cacing — Pembeda Utama
The defining feature of the NMRV-E150 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.
★ Flagship 15 kW IEC + Maximum Tail Shaft
The NMRV-E150 is the only standard aluminium worm gearbox that combines 15 kW IEC 160B5 direct flange mounting with a 50 mm tail shaft encoder output, delivering the maximum performance in the NMRV-E series.
◯ Same Torque as Standard NMRV150
The NMRV-E150 delivers identical maximum output torque (16,508 N·m) to the standard NMRV150, 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.
🅆 Encoder & Feedback Siap
Poros keluaran ekor menyediakan titik koneksi langsung untuk encoder putar, tachogenerator, dan generator pulsa yang memantau kecepatan poros cacing dalam sistem kontrol gerak loop tertutup, sehingga menghilangkan braket encoder eksternal dan perangkat keras kopling.
🚫 IP54 — Integritas Segel Ganda
Baik lubang keluaran utama maupun lubang keluar poros ekor disegel dengan segel bibir kontak ganda, mempertahankan perlindungan IP54 di semua orientasi pemasangan tanpa kebocoran oli pada antarmuka poros mana pun.

❓ Pertanyaan yang Sering Diajukan
What is the tail output shaft on the EP-NMRV-E150 and what is it used for?
The tail output shaft on the NMRV-E150 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-E150?
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 16,508 N·m, identical to the standard NMRV150.
What encoder types are compatible with the NMRV-E150 tail output shaft?
Poros ekor adalah poros berpasak standar yang dapat menerima encoder putar inkremental atau absolut apa pun dengan ukuran lubang yang sesuai. Pilihan umum meliputi encoder inkremental 5–24V (100–10.000 PPR), encoder absolut SSI, dan perangkat umpan balik tipe resolver. Konfirmasikan dimensi lubang dan pasak encoder dengan pemasok encoder sebelum memesan.
Which IEC motor flanges are available for the EP-NMRV-E150?
The NMRV-E150 accepts the following IEC input flanges: 100/112B5, 100/112B14, 132B5, 160B5. This covers the standard motor frame range for the 15 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E150 tail shaft be used to drive a secondary load simultaneously?
Ya, asalkan torsi beban sekunder pada poros ekor tidak melebihi kapasitas torsi tambahan poros cacing. Untuk beban sekunder ringan seperti pompa pelumasan kecil (di bawah 0,05 kW) atau katup pilot, poros ekor dapat digunakan secara bersamaan tanpa memengaruhi kinerja keluaran utama. Konsultasikan dengan tim teknik kami untuk beban sekunder di atas 0,05 kW.
⭐ Ulasan Pelanggan
★★★★★
“Our flagship NMRV-E150 drives the port grain conveyor head-end at ratio 100. The tail-shaft encoder feeds our terminal control system with belt speed data for automatic tonnage calculation. After 14 months of intensive operation, not a single maintenance issue.”
Tony V. — Terminal Engineer, Grain Export Port 🇦🇺 Australia (WA)
★★★★★
“We use four NMRV-E150 units on our heavy crane hoist drives. The tail-shaft high-resolution encoders provide 0.1 mm hoist position accuracy to our crane management system. The integrated encoder mount eliminated 32 hours of custom fabrication work.”
Anders L. — Mechanical Engineer, Offshore Platform 🇳🇴 Norway
★★★★☆
“The NMRV-E150 drives our large polymer reactor agitator. The tail-shaft encoder feeds our DCS with real-time agitator speed. We detected an early-stage bearing issue via speed variation trending and scheduled planned maintenance rather than facing an unplanned shutdown.”
Ibrahim A. — Plant Manager, Polymer Processing 🇪🇬 Egypt
