EP-NMRV090 Heavy-Duty Aluminium Worm Reducer – Product Overview

The EP-NMRV090 delivers genuine heavy-duty capability in an aluminium housing – up to 479 Nm output torque from input powers up to 4 kW. At 13 kg with 90 mm centre distance, it remains 40% lighter than comparable cast iron units while handling industrial conveyor head drives, large agitator mechanisms, and renewable energy tracking systems. The Ø35 mm output shaft with optional Ø38 mm matches heavy-duty coupling and sprocket standards used across Australian industrial applications. IEC motor frames from 56 to 180 connect via B5 or B14 flange – the widest motor range in the mid-NMRV series. Four output flanges FA, FB, FC, FD and compatibility with PC080 helical pre-stages provide maximum configuration flexibility for demanding continuous-duty applications.

✓ Core Features and Benefits

⚒ 479 Nm – True Heavy-Duty in Aluminium
Handles industrial conveyor heads, large agitators, and energy system drives at torques that previously required cast iron housings. The NMRV090 proves aluminium can compete at heavy-duty levels.

⚙ IEC Frames 56 to 180 – Widest Motor Range
Accepts motors from 0.37 kW to 4 kW directly via B5 or B14 flange. Frame 180 support enables heavy-duty industrial applications in an aluminium package that weighs 40% less than cast iron.

❄ 13 kg vs 22+ kg Cast Iron Equivalent
40% lighter than comparable cast iron. Enables field installation by two workers without overhead crane – critical for remote renewable energy sites and underground mining operations.

⚖ PC080 Helical Pre-Stage Compatible
Extends the ratio range to 240:1 with higher transmission efficiency than equivalent double-worm configurations. The standard approach for solar tracker drives and slow-speed positioning systems.

⚙ Industry Applications

☀ Solar Tracker Drives
90 mm aluminium worm reducer for photovoltaic panel tracking mechanisms. Paired with PC080 helical pre-stage, it achieves tracking ratios to 240:1 from a standard motor – the complete solar tracker drive solution.

☵ Process Agitator Drives
Large mixing vessel drives for chemical processing, water treatment, and food production. Ø35 or Ø38 output matches standard agitator shaft couplings directly without adaptor.

⚊ Industrial Conveyor Head Drives
Head drives for medium-heavy belt and chain conveyors in aggregate handling, timber processing, and recycling plants. 479 Nm handles loaded belt tension at sustained operating speeds.

⚒ Large Pump and Fan Drives
Low-speed drives for large dosing pumps, industrial ventilation fans, and cooling tower mechanisms up to 4 kW input power.

⚙ Selection Guide and Mounting Positions

Select the NMRV090 for output torque requirements between 172 Nm and 479 Nm at input power up to 4 kW. Step up to the NMRV110 at 648 Nm for heavier loads. The NMRV075 at 233 Nm is more cost-effective for moderate-heavy applications.

⚖ Aluminium vs Cast Iron – Heavy-Duty Comparison

At the 90 mm size class, the weight advantage of aluminium becomes increasingly significant for installation logistics and structural design. The NMRV090 at 13 kg replaces cast iron units weighing 22+ kg.

Feature	Aluminium NMRV	Cast Iron
Weight	30-50% lighter	Heavier
Corrosion	Excellent	Poor
Heat Dissipation	Superior	Moderate
Cost	Lower	Higher
Noise	Low	Moderate
IEC Motor	Direct B5/B14	Adaptor often needed

❓ Frequently Asked Questions

▶ What is the maximum output torque of the EP-NMRV090?

479 Nm at 30:1 ratio with approximately 3 kW input. At 100:1 ratio with 4 kW input: 302 Nm at 14 rpm output speed. Always verify service factor for your application.

▶ Does the NMRV090 support IEC frame 180 motors?

Yes. The NMRV090 is the first mid-range NMRV size accepting IEC frame 180 motors, enabling 4 kW input power for heavy-duty industrial applications.

▶ What is the PC080 helical pre-stage?

PC080 is a helical gear pre-stage that bolts onto the NMRV090 input flange. It provides ratios from 90:1 to 240:1 with higher transmission efficiency than equivalent double-worm combinations.

▶ When should I specify the Ø38 mm output shaft?

Choose 38 mm when output shaft radial or axial loads exceed the standard 35 mm shaft rating, or when your driven equipment uses 38 mm bore couplings or sprockets as standard.

▶ What is the thermal capacity of the EP-NMRV090 at 4 kW?

At 4 kW continuous input, verify thermal service factor remains above 1.0. Above 35°C ambient at 4 kW, consider duty cycle reduction or forced-air supplementary cooling.
