Schneider Electric BSH0553P11F2A Lexium 05 BSH 1.3 N·m 3000 rpm 55 mm Flange Brake Keyed Shaft Servo Motor

The Schneider Electric BSH0553P11F2A 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, with an integrated 0.8 N·m holding brake. 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.

Selection Notes

The BSH0553P11F2A shares its 1.3 N·m rating and 0.134-class low-inertia rotor with the plain BSH0553P11A2A, built for fast cyclic axes rather than high-inertia loads; the difference is the 0.8 N·m holding brake, which draws 10 W to release. That holding force is modest, so size it as a parking brake for a light vertical axis, not as a dynamic stop. It is cross-compatible with LXM05, LXM15, and LXM32 drives, and the single-turn SinCos Hiperface (P11) encoder reports absolute position on power-up without a homing move. The 10 W brake release draws from the drive's 24 V logic supply rather than the main power bus, which simplifies brake wiring on a single-axis machine.
