Product Description:
The MHD093C-058-PG0-BN is a servo motor built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. This model combines a 093 frame with length code C and incorporates digital servo feedback from an integrated optical encoder that provides absolute position measurement over more than 4096 revolutions. This feedback arrangement allows the connected drive to monitor rotor position directly for accurate speed regulation and positioning tasks in automated machinery. A plain shaft with a shaft seal couples the rotor to the load, while the power leads exit through a connector on side B to simplify cable routing.
Thermal management relies on liquid cooling, allowing the stator to deliver a continuous standstill torque of 23.0 Nm within the specified ambient range. The coolant jacket keeps the windings below the Class F insulation limit, and winding code 058 corresponds to electrical values used with compatible servo drives. Mechanical interface dimensions include a centering diameter of 130 mm and a flange pattern of 140 / 150 mm, supporting rigid mounting to gearboxes or cast machine frames. An enclosure rating of IP65 seals the housing against dust and water jets, so the motor can be mounted directly on production equipment where washdown or pressurized cleaning is present.
Operation is specified from 0 to 40 °C, and storage is permitted between -20 and +80 °C to protect magnet integrity during transport and idle periods. System repeatability benefits from a positioning accuracy of ± 0.5 angular minutes, which supports tight alignment tasks without an external encoder. Because the unit is supplied without a holding brake, external load-holding measures are required when power is removed, especially on axes that must remain fixed at standstill. Installation is approved up to 1000 m above sea level, supporting stable thermal behavior and commutation in elevated facilities.
