Product Description:

The MHD115C-058-NG1-RA is a servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. Its frame size 115 and length code C suit medium-to-large automation axes that couple directly through the plain shaft. The unit uses relative position detection with a digital encoder, and an integrated holding brake secures the load when power is removed. Typical deployments include packaging stations, gantry slides, and transfer lines that need consistent motion across long duty cycles.

Its continuous stall capability reaches 70.0 Nm, meaning the motor can deliver this torque indefinitely without overheating when powered by drives matched to winding code 058. The IP65 housing resists dust ingress and water jets, which is useful on machinery that is cleaned between shifts. Position feedback is supplied by digital servo feedback (HSF), which uses an optical measurement method to relay high-resolution angle data to the controller. The square front flange measures 192 mm and aligns to a 180 mm centering diameter for rigid mounting on gearboxes or plates. During operation, the device can be installed in environments from 0 to 40 °C, and heat from the stator is released through natural convection so no external blower is required.

System precision stays within ± 0.5 angular minutes, so incremental moves remain within tight tolerance without iterative correction. The windings use Class F insulation, allowing elevated internal temperatures while still respecting the ambient limit. The power feed enters on the side oriented to the right of the shaft, and the removable power connector preserves sealing during service. A shaft seal prevents lubricant migration toward the bearing seats. For load securing, the brake remains rated for operation up to 1000 m above mean sea level. When stored, the unit withstands -20 to +80 °C.
