Schneider Electric BSH0703P11A2A Lexium 05 BSH 2.8 N·m 3000 rpm 70 mm Flange Keyed Shaft Servo Motor
Lexium 05 BSH servo motor, 2.8 N·m continuous, 70mm flange, keyed shaft, no brake.
Description
About the BSH
About the BSH
The Schneider Electric BSH0703P11A2A is a Lexium 05 series low-inertia servo motor rated for 2.8 N·m continuous stall torque at 3000 rpm on a 70 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
The BSH0703P11A2A shares the 70 mm flange with the BSH0701 and BSH0702 but carries the highest continuous stall current of the three at 4.1 A, so it draws the most from its paired drive even at a comparatively modest 2.8 N·m continuous torque — a sign it is built for speed and dynamic response more than peak torque. It is cross-compatible with LXM05, LXM15, and LXM32 drives. Without a brake, this A2A variant suits horizontal or balanced axes; choose the F2A version in the same frame for loads that must hold position unpowered. Its single-turn SinCos Hiperface (P11) encoder reports absolute shaft position at every power-up, so the axis skips a dedicated homing move before the first cycle.
