Schneider Electric BMH1003P16A2A Lexium 32 BMH 8.4 N·m 6000 rpm 100 mm Flange Keyed Shaft Servo Motor
Schneider Electric BMH1003P16A2A Lexium 32 BMH 8.4 N·m servo motor, 100 mm flange.
Description
About the BMH
About the BMH
The BMH1003P16A2A is a Schneider Electric Lexium 32 BMH medium-inertia servo motor rated 8.4 N·m continuous stall torque at 6000 rpm maximum mechanical speed, built without a holding brake on a 100 mm international standard flange. It pairs with the LXM32.D30N4 servo drive and reports position through a single-turn SinCos Hiperface encoder (32768 points/turn) for automatic motor identification at drive start-up.
Selection Notes
At 8.4 N·m continuous stall torque and 7.69 A continuous stall current, the BMH1003P16A2A sits on the 100 mm BMH frame size paired with the LXM32.D30N4 servo drive. Choose this brake-less variant over the BMH1003P16F2A for horizontal axes where the load cannot back-drive the motor when power is removed; it skips the brake pull-in current and the extra shaft length the brake-equipped version adds on the same 100 mm frame. The 32768-point/turn single-turn SinCos Hiperface encoder reports absolute position directly to the drive, so no separate homing move or battery-backed multi-turn encoder is required for single-turn axes.
Applications
As a medium-inertia BMH motor, it fits load profiles where inertia matching to the driven mechanism matters as much as raw acceleration: ball-screw and belt axes, indexing tables and gantry drives on packaging and material-handling machines are typical fits for this torque and speed class.
