Product Description:

The MHD071B-035-PP3-UN servo motor is produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for integration into servo axes that require rapid acceleration, accurate positioning, and continuous duty. By converting controlled current from a drive controller into mechanical rotation, the unit provides a compact actuator for packaging lines, handling robots, and machining centers. Its operating role fits automated equipment that must maintain smooth motion during indexing, transfer, and repeated start-stop cycles.

The mechanical interface includes a flange diameter of 115 mm and a centering pilot of 95 mm, allowing drop-in mounting on IEC-compliant gearboxes or frames. At standstill, the motor can deliver a continuous torque of 8.0 Nm, supported by the winding and magnetic layout of this frame size. Heat generated during rated loading is removed through liquid cooling channels in the housing, so nominal output can be maintained without external airflow. Position and speed are monitored by digital servo feedback that combines a multiturn encoder with electronic motor data, allowing the drive controller to close high-resolution loops automatically.

During power loss, the integrated holding brake clamps the rotor with 10.0 Nm of torque, helping prevent vertical loads from drifting. The encoder provides absolute position tracking over more than 4,096 revolutions, eliminating the need for homing moves after startup. Electrical terminations use rotatable connectors; the power plug is rotatable through 270° to ease cable routing in tight cabinets, and a separate feedback socket carries signals to the drive. Motion is transmitted through a keyed shaft with a shaft seal that helps block lubricants and dust, and the B-length body leaves space for adjacent modules.
