Product Description:

The MHD071B-035-PG1-UN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It is intended for closed-loop industrial automation where precise speed and position control are required on compact mechanical axes. An integrated digital feedback device allows the paired drive to monitor rotor position continuously during motion and holding operation. The motor supplies torque directly to the load, which helps simplify drivetrain layouts in packaging, pick-and-place, and forming machinery.

This motor can deliver a continuous standstill torque of 8.0 Nm, allowing stable force output during static holding or low-speed moves. Heat generated under that load is removed through liquid cooling, so thermal derating is minimized even in dense multi-axis cabinets. A centering boss of 95 mm aligns the housing to mounting fixtures, while the square flange spans 115 mm for compatibility with common mechanical interfaces. The motor uses a plain shaft without keys or splines, and the shaft seal helps keep lubricant and contaminants away from internal parts. Position data come from an integrated digital servo feedback encoder in the rear section, and the B motor length gives an intermediate size for balanced inertia and torque capability.

For power-off safety, the unit includes a holding brake with 5.0 Nm of static locking torque. The power connector can be rotated through a 270° range so cable routing can better match enclosure constraints. Absolute position tracking over >4096 revolutions allows the drive to retain position information after power is restored. The motor frame size is 071, which keeps the package compact for dynamic duty. The winding code is 035, which matches the resistance and inductance values expected by compatible Rexroth drive amplifiers.
