✅ 핵심 기능 및 고유한 이점
🔗 웜 기어 방향 테일 출력 샤프트 — 핵심적인 차별점
The defining feature of the NMRV-E050 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.
🅆 VFD + Encoder in One Unit
The NMRV-E050 works seamlessly with VFD-driven IEC motors while the tail shaft simultaneously provides speed/position feedback, creating a closed-loop VFD-gearbox-encoder assembly without external sensor brackets.
◯ Same Torque as Standard NMRV050
The NMRV-E050 delivers identical maximum output torque (4,280 N·m) to the standard NMRV050, 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.
🅆 인코더 및 피드백 지원
꼬리 출력 샤프트는 폐쇄 루프 모션 제어 시스템에서 웜 샤프트 속도를 모니터링하는 회전 엔코더, 타코제너레이터 및 펄스 발생기를 직접 연결할 수 있는 지점을 제공하여 외부 엔코더 브래킷 및 커플링 하드웨어를 제거합니다.
🚫 IP54 — 이중 밀봉 무결성
주 출력부와 테일 샤프트 출구 모두 이중 접촉 립 씰로 밀봉되어 모든 장착 방향에서 IP54 보호 등급을 유지하며 샤프트 인터페이스에서 오일 누출이 발생하지 않습니다.
🏭 적용 시나리오

❓ 자주 묻는 질문
What is the tail output shaft on the EP-NMRV-E050 and what is it used for?
The tail output shaft on the NMRV-E050 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-E050?
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 4,280 N·m, identical to the standard NMRV050.
What encoder types are compatible with the NMRV-E050 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-E050?
The NMRV-E050 accepts the following IEC input flanges: 63B5, 63B14, 71B5, 71B14, 80B14. This covers the standard motor frame range for the 1.1 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E050 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 industrial mixer uses an NMRV-E050 with a tail-shaft tachometer. The tachometer signal feeds our VFD controller and maintains constant impeller tip-speed across varying product viscosities. Mixing uniformity has improved significantly.”
Rosa K. — Process Engineer, Food Ingredients 🇳🇿 New Zealand
★★★★★
“We installed NMRV-E050 units on our wastewater filter screen drives. The tail-shaft pulse counters feed our SCADA system, providing operators with real-time rotation confirmation and instant stall alerts. Highly reliable after 18 months.”
Carlos M. — Plant Manager, Water Treatment Authority 🇨🇱 Chile
