Description
About the BMH
About the BMH
The Schneider Electric BMH0702P16F2A is the braked version of Schneider's 2.5 N·m Lexium 32 BMH servo motor for the LXM32.D12N4 drive, matching the BMH0702P16A2A's 700 W nominal output power and 8000 rpm maximum mechanical speed. Its 3 N·m holding brake adds length and mass over the brake-less sibling, letting a vertical or clamped axis hold position once the drive is de-energized.
Selection Notes
The BMH0702P16F2A adds a 3 N·m holding brake to the BMH0702P16A2A's 2.5 N·m, 700 W motor without changing the LXM32.D12N4 drive pairing or the 70 mm flange — pick it for a vertical or clamped axis that must hold position the instant the drive loses power. The brake extends the motor from 154 mm to 193 mm and adds roughly 1 kg of net weight, rising from 2.3 kg to 3.3 kg, and its 7 W pull-in power is a small but real addition to the drive's control-supply budget. Torque, current and shaft dimensions otherwise match the brake-less sibling exactly, so the choice is purely about whether the axis needs a powered-off hold, not about output rating or drive sizing.
