Schneider Electric BSH0553P11A2A Lexium 05 BSH 1.3 N·m 3000 rpm 55 mm Flange Keyed Shaft Servo Motor

The Schneider Electric BSH0553P11A2A is a Lexium 05 series low-inertia servo motor rated for 1.3 N·m continuous stall torque at 3000 rpm nominal on a 55 mm flange. It runs on a 480 V three-phase supply, pairs with LXM05, LXM15, or LXM32 drives, and uses a keyed shaft with a single-turn SinCos Hiperface encoder. No holding brake is fitted on this variant.

Selection Notes

At 0.134 kg·cm² rotor inertia, the BSH0553P11A2A sits in the low-inertia class built for fast, repetitive cyclic axes rather than high-inertia loads — pick it over a BSH07/BSH10 frame when the mechanism itself is light and the limiting factor is acceleration, not torque. It is cross-compatible with LXM05, LXM15, and LXM32 drives in the same current class, so the drive choice can follow whatever family the rest of the machine already uses. The single-turn SinCos Hiperface (P11) encoder reports absolute position on power-up without a homing move. Without a brake, this A2A variant needs an external holding method on vertical axes — the F2A version in the same 55 mm frame adds one.
