Schneider Electric BMH1901P21A2A Lexium 32 BMH 30 N·m 5000 rpm 190 mm Flange Untapped Shaft Servo Motor

The Schneider Electric BMH1901P21A2A is a Lexium 32 series servo motor rated for 30 N·m continuous stall torque on a 190 mm flange, built for a 480 V three-phase supply. Paired with an LXM32D72N4, LXM32MD85N4, or LXM32MC10N4 drive, it delivers up to 5.18 kW nominal output power. It has a smooth untapped shaft, no holding brake, and a single-turn SinCos Hiperface encoder.

Selection Notes

Across the LXM32D72N4, LXM32MD85N4, and LXM32MC10N4 pairings, the BMH1901P21A2A holds the same 30 N·m continuous torque — what changes is nominal speed headroom, from 2500 rpm on the 24 A drive to 3000 rpm on the 32 A and 40 A drives at the same torque. Pick the higher-current drive when the axis needs faster cycling at full torque rather than more torque. This is the A2A (no-brake) variant: on a vertical or gravity-loaded axis, the F2A holding-brake variant in the same 190 mm frame holds position when power is removed, which this motor cannot do on its own.
