Product Description:

The MHD115C-058-PP0-RA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop motion control, it works with a digital drive to deliver regulated torque and speed to automated axes used in machining centers, feeders, and packaging stations. The motor uses a keyed shaft and a power connector that exits to the right, which helps simplify installation in compact machine layouts. An integrated multi-turn absolute encoder provides repeatable position feedback over long travel distances, and the optical measurement method supports stable signal quality without mechanical wear in the feedback system.

Winding code 058 gives the motor a continuous standstill torque of 70.0 Nm. Mechanical alignment is supported by a 180 mm pilot and a 192 mm flange width for secure mounting to the machine face. The housing is rated IP65, which helps protect internal components from dust and water jets when the cable entries are sealed correctly. Optical digital servo feedback provides a positioning accuracy of ± 0.5 angular minutes, and the absolute encoder stores more than 4096 revolutions of position data. The C-length frame is cooled by natural convection through the motor housing, allowing heat to dissipate without external blowers or liquid circuits.

Storage is permitted from -20 to +80 °C, while operation is allowed from 0 to 40 °C in normal ambient conditions. Installation is permitted up to 1000 m above sea level. The motor includes a shaft seal to protect the bearing area, and it is supplied without a holding brake, so a stopped load must be secured by the drive or by external mechanical means during power loss. Insulation Class F is used in the winding system, allowing the motor to tolerate winding temperatures up to 155 °C. These temperature limits should be observed so the encoder, insulation, and sealing elements are not exposed to unnecessary thermal stress during storage or operation.
