Product details

400 W, 1.27 N.m — the torque curve that matters

The BEH18MD0433CA5C: This BEH18 servo motor delivers 400 W continuous output power at 220 V single-phase, with a nominal torque of 1.27 N.m and a peak stall torque of 4.45 N.m under the same supply conditions. The 1.27 N.m continuous stall torque matches the nominal figure — meaning the motor holds rated torque at standstill without derating, which matters for positioning applications that dwell under load.

IP67 sealed, no holding brake — field-fit constraints

The motor body carries an IP67 rating, meaning it withstands dust ingress and temporary immersion — suitable for washdown environments in food processing or packaging lines. The shaft seal and connector interface are the wet-end barriers; the IP67 rating applies when the mating connectors are properly seated. There is no holding brake on this variant. The shaft end is a 14.0 mm diameter parallel key with a 30.0 mm shaft length and 5.0 mm key width. The Asian standard flange (60 mm square) with four mounting holes bolts directly to common servo gearboxes or machine frames. Without a brake, the motor relies on the drive's holding torque at standstill or an external mechanical brake for vertical-axis loads.

Sourced through independent distribution channels.

Frequently asked questions

What is the feedback type on this motor?

It uses a 23-bit optic multi-turn encoder for absolute position feedback. The multi-turn capability tracks shaft position across multiple revolutions without a battery backup.

Does this motor include a holding brake?

No, this variant ships without a holding brake. For vertical-axis loads or applications requiring fail-safe holding, an external brake or the drive's holding torque at standstill must be used.
