Schneider Electric BMH1902P21F2A Lexium 32 BMH 48 N·m 4000 rpm 190 mm Flange Brake Untapped Shaft Servo Motor
Lexium 32 BMH servo motor with brake, 48 N·m continuous, 190mm flange, 480V, untapped shaft.
Description
About the BMH
About the BMH
The Schneider Electric BMH1902P21F2A is a Lexium 32 series servo motor rated for 48 N·m continuous stall torque on a 190 mm flange, with an integrated 80 N·m holding brake, built for a 480 V three-phase supply. Paired with an LXM32MD85N4 or LXM32MC10N4 drive it delivers 6.07 kW nominal output power. It has a smooth untapped shaft and a single-turn SinCos Hiperface encoder.
Selection Notes
The BMH1902P21F2A's 48 N·m rating only applies with the 32 A LXM32MD85N4 or 40 A LXM32MC10N4 drive; the 24 A LXM32D72N4 pairing caps it at 37.4 N·m, so the drive choice directly sets the usable torque. The 80 N·m integrated holding brake needs 40 W to release and holds the axis the moment power is removed, which is what separates this F2A variant from the plain A2A motor — specify it for vertical or overhauling loads where the axis must not drift with the drive de-energized.
