Product Description:

The MHD071B-035-PP2-UN servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated machinery it converts electrical power into tightly controlled rotary motion, forming the primary drive element in packaging lines, handling modules, and light-duty machining centers. The compact 071 frame and B length option help integrators keep moving mass low while still achieving the torque needed for medium-power axes. Integrated digital feedback supports closed-loop control, so the drive maintains position accuracy as load and temperature change.

The motor sustains 8.0 Nm of continuous standstill torque, meaning it can hold a static load indefinitely without exceeding its thermal limits. That capability is maintained by a housing that uses liquid cooling, which removes heat directly from the stator jacket and permits higher current density than air-cooled designs. A centering pilot of 95 mm aligns the motor precisely to gearboxes or machine frames, while the square flange measuring 115 mm sets the bolt pattern for secure mounting. Electrical terminations are simplified because the power connector is turnable through 270°, so the plug can be oriented to avoid cable clashes in tight enclosures.

For static safety, the integrated brake generates 6.5 Nm of holding torque, locking the shaft when the drive is disabled or during emergency stops. Mechanical output is transferred through a keyed shaft, providing positive engagement with couplings and preventing slip under load reversals. Multi-turn feedback is delivered by an encoder with absolute resolution for more than 4096 revolutions, so the controller reads the exact position immediately after power-up without a homing move. Electrical parameters follow winding designation 035, ensuring the motor’s resistance and inductance match drive inverters that operate on moderate bus voltages and current ranges.
