Product Description:

The MHD071B-061-BP3-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It delivers controlled rotary power to indexing tables, linear actuators, and similar industrial automation axes. With a compatible drive controller, it supports precise speed and position regulation during start, stop, and indexing moves. Because it is a synchronous servo motor, it is well suited to applications that need repeatable motion and controlled acceleration. The frame follows the 071 size code, giving it a compact envelope that fits multi-axis assemblies without major layout changes.

The motor uses a square flange of 115 mm, and a 95 mm centering diameter keeps the housing aligned on the machine plate. Continuous torque at standstill is rated at 8.0 Nm, allowing the axis to hold a steady load during low-speed or stationary operation. Heat is removed by built-in liquid cooling, which circulates coolant through the stator jacket and helps keep winding temperature under control. The motor uses winding code 061, which identifies the electrical values used with compatible Rexroth digital drives. Length designation B gives the motor a medium housing length, and separate rear-facing power and feedback connectors help keep cable paths organized. This layout can simplify routing in dense multi-axis assemblies.

A factory-installed holding brake supplies 10.0 Nm of static torque to keep the axis in position when power is removed. The power connector is rotatable through 270°, so the cable exit can be aligned with surrounding machine hardware and enclosure routing. Torque is transmitted through a keyed shaft, and a shaft seal helps reduce contamination at the bearing journal. This arrangement is useful in compact machines where cable space and access around the motor are limited. The brake can also help prevent axis drift during controlled stops or idle periods.
