Product Description:

The MHD071B-035-NP1-UN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop drive element, it converts electrical energy into commanded mechanical motion and supplies precise position and speed control for automated axes in packaging lines, machine tools, and material-handling cells. The motor’s mid-frame geometry allows it to fit compact multi-axis platforms while maintaining the repeatability required in industrial automation.

This model delivers a continuous standstill torque of 8.0 Nm, allowing the axis to hold or slowly index loads without thermal overload. Heat is extracted through a liquid cooling jacket, so full ratings are retained even when the frame is surrounded by other heat sources. The motor is rated IP65, which prevents dust penetration and protects against low-pressure washdown. Rotor position is resolved by a Digital servo feedback (HSF) encoder that reports high-speed data to the drive controller. Mounting follows a 115 mm square flange, and a keyed shaft transfers torque to the load. Other features include optical rotor-angle measurement, a relative position reference, frame size 071 with B length, winding code 035, power and feedback connectors that can be turned within 270°, operation in ambient temperatures from 0 to 40 °C, and installation up to 1000 m above mean sea level.

The integrated holding brake secures the shaft with 5.0 Nm of static torque, supporting vertical or suspended loads during power-off conditions. A centering pilot of 95 mm simplifies coaxial alignment, and a shaft seal helps block lubricant migration into the motor interior. The windings use insulation class F, which supports higher allowable temperature limits during cyclic duty. The system accuracy is ± 0.5 angular minutes, supporting precise closed-loop positioning. Storage temperatures range from −20 to +80 °C, allowing the motor to remain in storage or transit without affecting its insulation system or magnetic components.
