Schneider Electric BMH1901P21F2A Lexium 32 BMH 30 N·m 5000 rpm 190 mm Flange Brake Untapped Shaft Servo Motor

The BMH1901P21F2A is a Schneider Electric Lexium 32 BMH medium-inertia servo motor rated 30 N·m continuous stall torque at 5000 rpm maximum mechanical speed, built with a holding brake and an untapped (smooth) shaft on a 190 mm international standard flange. It is IP65-rated as standard (IP67 with the optional kit) and pairs with the LXM32.D72N4, LXM32MD85N4 or LXM32MC10N4 servo drive, using a single-turn SinCos Hiperface encoder (131072 points/turn) for absolute position feedback.

Technical Specifications

Selection Notes

The 30 N·m continuous stall torque on the BMH1901P21F2A is identical across all three compatible drives (LXM32.D72N4, LXM32MD85N4, LXM32MC10N4), so the drive choice is set by available supply current rather than torque headroom — 24 A, 32 A or 40 A. Pick the smallest-current drive the application allows to limit cabinet size and cost. Against the brake-less BMH1903P21A2A on the same 190 mm frame, this motor trades maximum torque for the 80 N·m holding brake, making it the choice when the axis must hold a vertical or overhauling load with power removed. The smooth untapped shaft and 131072-point/turn encoder resolution (four times the 32768-point encoders on the smaller BMH frames) suit higher-precision positioning tasks at this power class.

Applications

At 4.8-5.18 kW with a holding brake, this motor fits heavier gantry, hoist and lift-axis applications on packaging and material-handling lines where the brake must hold the load when the drive is de-energized.
