✅ Fitur Utama & Manfaat Unik
🔗 Poros Keluaran Ekor Arah Cacing — Pembeda Utama
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.
🅆 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-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?
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-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?
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.
