MHD115B-058-PP1-BN
MHD Synchronous Motors
The MHD115B-058-PP1-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It serves as a rotary axis drive in automated machining centers, transfer lines, and material-handling stations where precise speed and position control are required. Integrated feedback electronics let the drive regulate torque and velocity without external sensors, while the housing design supports high thermal loads encountered in continuous industrial operation.
The motor mounts through a centering diameter of 180 mm and a square flange that measures 192 mm, allowing direct placement on heavy machine frames. It can produce a continuous standstill torque of 50.0 Nm, a value that defines the maximum static load it can hold without exceeding thermal limits. Heat generated at this rating is extracted by liquid cooling that circulates through channels in the stator jacket to stabilize winding temperature. Mechanical dimensions follow length code B and size 115, while the electrical package is defined by winding code 058. Power is delivered through an output connector oriented to side B, simplifying cable runs in cabinets where multiple axes are stacked.
When power is removed, the integrated holding brake delivers 70.0 Nm of locking torque to secure vertical or cantilevered loads. Torque is transmitted through a Keyed Shaft, and a shaft seal prevents coolant or lubricant from entering the bearing cavity. Position feedback is handled by digital servo electronics that provide Absolute (>4096 revolutions) information, eliminating homing cycles after shutdown. Drive tuning is matched to winding code 058, ensuring current limits and commutation tables align with the motor’s electrical characteristics.
