NUODUN NDP001 Coaxial Planetary Reducer

MANUFACTURER DOCUMENTATION

Overview

The NDP001 rating sheet is published within Nuodun’s ND-LDB5-AM80B5 product documentation. This page extracts the one-stage NDP001L1 configurations at 1,400 rpm input. Actual ratios differ from the nominal selection labels: for example, the nominal 3.55 entry is listed as 3.577 actual ratio, with 125 Nm output torque and 391 rpm output speed. The sheet also gives a 3 kW thermal-power value for the one-stage group. Thermal capacity and mechanical torque are different checks. The configurations here retain the actual ratios; confirm the motor interface, bearing loads and thermal operating conditions with the manufacturer.

Before you specify this gearbox

A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

Confirm continuous, peak and emergency-stop load limits separately.
Match the motor flange, shaft, mounting orientation and lubrication requirements.
Request the current drawing revision and selection calculation from the manufacturer.
