Product Description:

The MHD093C-058-PP1-LA synchronous servo motor is built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a rotary actuator in industrial automation and works with compatible servo drives to provide controlled, repeatable motion for packaging lines, gantries, and transfer stations. The integrated absolute feedback system lets the drive detect rotor position as soon as power is restored, so the axis does not need a homing cycle after startup or after a brief power interruption.

The winding code 058 is paired with a continuous standstill torque of 23.0 Nm, giving the drive enough margin for moderate-inertia loads. A sealed housing rated at IP65 blocks dust and water jets so the motor can be mounted on open machine frames. Heat leaves the stator through natural convection, so no external blower or liquid circuit is required. Windings are insulated to Class F, allowing temperatures up to 155 °C before thermal limits are reached. A centering diameter of 130 mm aligns the flange with gearboxes or adapter plates and helps keep radial runout low. Digital servo feedback with an integrated absolute encoder measures rotor angle optically over more than 4096 revolutions, while the keyed shaft helps prevent slip and the included shaft seal helps limit lubricant ingress. Power wiring enters from the left through a molded power connector, which keeps the electrical interface compact and simplifies cable changes.

A holding brake supplies 22.0 Nm of static torque so vertical axes remain fixed during power loss. The square flange measures 140 / 150 mm, matching the size 093 frame and offering multiple bolt patterns. Closed-loop accuracy is held within ± 0.5 angular minutes, supporting precise indexing at reduced cycle times. The motor operates anywhere from 0 to 40 °C, stores safely between −20 and +80 °C, and can be installed up to 1000 m above mean sea level without derating during normal operation.
