Schneider Electric BSH1402P11A2A Lexium 05 BSH 14.9 N·m 1500 rpm 140 mm Flange Untapped Shaft Servo Motor

The BSH1402P11A2A is a Schneider Electric Lexium 05 BSH low-inertia AC servo motor rated for 14.9 N·m continuous stall torque at 1500 rpm nominal speed, built on a 140 mm international standard flange. It uses a untapped shaft and ships without brake, paired with Lexium servo drives via a single-turn SinCos Hiperface absolute encoder.

Selection Notes

At 14.9 N·m continuous stall torque on a 140 mm flange, this is the low-inertia class of the Lexium 05 line, suited to fast point-to-point and cyclic motion (pick-and-place, indexing) rather than constant-load conveying. The untapped shaft is intended for clamp-type couplings on this 140 mm frame, avoiding the stress riser a keyway introduces at this torque level; choose a keyed-shaft BSH10xx motor instead if the application already uses keyed couplings. It ships without brake, for horizontal or balanced axes where the LXM05/LXM15 drive's regenerative braking holds the load during a stop; where the axis must hold position with the drive off, the equivalent 'F' brake variant of this same frame is the one to specify. The single-turn SinCos Hiperface absolute encoder (131,072 counts/revolution) reports exact shaft angle within one mechanical turn without a battery, so the drive reads position on power-up without a separate homing move for single-turn travel. Continuous stall current is 13.2 A and maximum permanent current 44.1 A: size the paired LXM05/LXM15 drive to this continuous rating rather than the frame's peak figure, and re-check drive sizing before substituting a different torque variant of this same 140 mm flange into an existing design.
