4 kW at 3000 rpm — torque and inertia match
The BEH18LM4033CA6D: Peak stall torque hits 37.8 N.m at 380 V, giving a 3:1 torque overload margin for acceleration through dwells or short-duration cuts. The continuous stall current of 12.96 A and maximum current of 38.88 A at 4 kW define the drive sizing envelope — match the drive's continuous and peak current ratings to these numbers, not the nominal.
23-bit optic multi-turn encoder — position loop resolution
The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution absolute position. At 3000 rpm the encoder output frequency sits around 419 MHz — well within the range of modern motion controllers, but the cable length and shielding matter for signal integrity. The feedback resolution supports velocity loop bandwidths above 100 Hz on a well-tuned system. Back EMF constant is 67.87 V/krpm at 40 °C; torque constant is 0.9722 N.m/A at the same temperature. These two numbers let you calculate the drive's required DC bus voltage for a given speed and the current loop gain for torque control. The IP67 rating on the housing means this motor survives washdown environments — the encoder connector and power connector seals are the critical path.
Asian standard flange, without holding brake
The 130 mm Asian standard flange with 9 mm mounting holes and four-hole pattern matches the common B5 / FF130 interface used across many Asian-sourced machine frames. No holding brake is fitted — this motor relies on the drive's holding torque at standstill or an external brake. If the application requires vertical-axis holding, an external spring-applied brake on the shaft or a separate brake motor is needed.
