Product Description:
The MHD071B-061-NP0-UP is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop drive systems, it uses a relative optical position sensor so the connected controller can issue precise velocity and position commands in pick-and-place modules, tool changers, or feeder lines. The B-length 071 frame, keyed shaft, and combined power and feedback connections give the motor a compact mechanical interface for flange-mounted machinery. Because the feedback device is integrated into the motor, the drive can monitor rotor movement without a separate external measuring device.
The motor delivers a continuous standstill torque of 8.0 Nm, providing stable holding force when motion is paused. The enclosure is rated IP65, which helps protect internal components from dust and water jets in industrial service. Rotor position reaches the drive through Digital servo feedback (HSF). Mechanical attachment uses a 115 mm flange with a 95 mm centering bore for accurate alignment at the machine face. Heat generated in the stator is released by natural convection, so forced airflow is not required. A shaft seal supports IP68 protection at the output side.
The insulation system is rated at Class F, allowing winding temperatures up to 155 °C without degradation. The motor operates continuously at ambient temperatures from 0 to 40 °C and can be stored from -20 °C to 80 °C without affecting magnet strength. Combined servo electronics and precision mechanics keep cumulative positioning error within ± 0.5 angular minutes, which supports multi-axis interpolation and repeatable path control. For easier cable routing inside tight enclosures, the power connector can be rotated through 270°, allowing strain-relief loops regardless of mounting orientation. The motor does not include a holding brake, which reduces mass when braking or load holding is handled elsewhere. Operation is permitted up to 1000 m above mean sea level, and the motor uses winding code 061.
