Schneider Electric BMH0703P16A2A Lexium 32 BMH 3.4 N·m 8000 rpm 70 mm Flange Keyed Shaft Servo Motor

The Schneider Electric BMH0703P16A2A is a Lexium 32 BMH servo motor delivering 3.4 N·m continuous stall torque, paired with the LXM32.D18N4 servo drive for a 1300 W nominal output at 5000 rpm nominal speed. It draws 3.91 A continuous stall current from a 480 V three-phase supply and reaches 8000 rpm maximum mechanical speed. The keyed-shaft, IP54-rated motor has no holding brake and mounts on a 70 mm international-standard flange.

Selection Notes

At 3.4 N·m continuous stall torque and 1300 W nominal output with the LXM32.D18N4 drive, the BMH0703P16A2A sits a step above the lower-torque BMH motor in the same family and suits higher-load axes within the same 70 mm flange footprint. It ships without a holding brake, so it is the choice for horizontal axes where the load cannot drift under gravity when the drive de-energizes; axes that need position retention on power loss should use a braked BMH variant instead. The 14 mm keyed shaft end transmits torque directly without relying on a friction clamp.

Applications

Within the Lexium 32 line, this torque and current class suits conveyor and indexing axes, winding stations, and small robotic joints that run horizontally and do not need the drive-off brake holding function. The 70 mm flange keeps it mechanically interchangeable with other BMH motors in the same frame for mixed-axis machine designs.
