Schneider Electric BMH0702P16A2A Lexium 32 BMH 2.5 N·m 8000 rpm 70 mm Flange Keyed Shaft Servo Motor
Lexium 32 BMH servo motor, 2.5 N·m continuous stall torque, 70 mm flange, keyed shaft, single-turn SinCos Hiperface encoder, no brake.
Description
About the BMH
About the BMH
The Schneider Electric BMH0702P16A2A is a Lexium 32 BMH servo motor sized for the LXM32.D12N4 drive, delivering 2.5 N·m continuous stall torque and 700 W nominal output power at 3000 rpm nominal speed. Built on the same 70 mm flange and keyed shaft as the lower-torque BMH0701P16A2A, it spins to 8000 rpm maximum mechanical speed and ships without a holding brake.
Selection Notes
The BMH0702P16A2A is sized specifically for the LXM32.D12N4 drive, delivering 2.5 N·m continuous stall torque and 700 W nominal output power at 3000 rpm nominal speed — roughly double the BMH0701P16A2A's D12N4-paired rating in the same 70 mm flange and keyed-shaft format. It ships without a holding brake, so it suits axes that do not need to hold a load once the drive is de-energized; the BMH0702P16F2A carries the identical torque and power rating with a 3 N·m brake added. Its 9.68 A maximum permanent current, not the 2.94 A continuous rating, is what sizes the LXM32.D12N4 drive's output stage for peak-demand moves. Rotor inertia of 1.13 kg.cm² and a 2.3 kg net weight both nearly double the BMH0701P16A2A's corresponding D12N4-paired figures along with the torque and power rating.
