Description
About the BMH
About the BMH
The Schneider Electric BMH0703P16F2A is a Lexium 32 BMH servo motor sized for the LXM32.D18N4 drive, rated for 3.4 N·m continuous stall torque and 1300 W nominal output power at 5000 rpm nominal speed, with an 8000 rpm maximum mechanical speed. Its keyed shaft, 70 mm flange and 3 N·m holding brake match the smaller BMH07 motors, but a larger 14 mm shaft marks it as the highest-torque motor in the BMH07 frame.
Selection Notes
The BMH0703P16F2A is the highest-torque motor in the BMH07 frame, paired with the LXM32.D18N4 drive for 3.4 N·m continuous stall torque and 1300 W nominal output power at 5000 rpm nominal speed — nearly double the BMH0702P16F2A's output in the same 70 mm flange. Its 14 mm shaft, versus 11 mm on the lower-torque BMH07 motors, and 3.91 A continuous stall current size the mechanical coupling and drive output stage accordingly. The standard 3 N·m holding brake carries over from the BMH0702P16F2A for powered-off position hold, adding the same 7 W pull-in power draw to the drive's control supply, and the same 10.2 N·m peak-to-continuous torque ratio seen across the BMH07 line.
