Product Description:

The MHD071B-061-PP0-UN synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for closed-loop automation, the unit converts drive-controller commands into precise rotary motion for packaging lines, transfer stations, and similar equipment. Its 071 frame and B-length housing fit compact machine layouts that need continuous motion accuracy. The motor is suited to axes that perform frequent starts, stops, and position corrections during normal operation.

The motor delivers a continuous standstill torque of 8.0 Nm, permitting stable holding force when the rotor is energized and not turning. Heat is removed through liquid cooling, so coolant circulates around the stator jacket instead of relying on surrounding air. A 115 mm square mounting flange fixes the bolt pattern, and the 95 mm centering diameter keeps the housing aligned with the machine interface. The output uses a keyed shaft, which provides positive torque transmission to pulleys, couplings, or gearboxes. This arrangement is useful in enclosed equipment where ambient airflow is limited.

Electrical connections are made through separate power and feedback connectors, and the power plug can be rotated through a range of 270° to suit cable routing. Rotor position is monitored by digital servo feedback with an integrated encoder, and the sensor supplies absolute position information over more than 4096 revolutions to the drive so reference data is retained after power loss. The stator winding uses code 061, which matches the electrical characteristics expected by compatible MHD drives. A shaft seal helps keep contaminants away from internal components, and the motor is supplied without a holding brake. If the load must remain fixed while power is off, that holding function must be provided elsewhere in the system.
