Product Description:

The MHD093B-058-NP1-AA is a servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as a dynamic drive element for automated handling equipment, press feeders, and machining centers, where closed-loop control of torque and speed is required. The motor interfaces with Rexroth drives through its side-A output connector and digital position feedback, enabling coordinated multi-axis motion without mechanical gearboxes.

The motor delivers a continuous standstill torque of 17.5 Nm, letting driven axes hold load during normal operation. The housing meets the IP65 protection class, so dust ingress and water jets do not affect windings rated to insulation class F. Position is measured by a digital servo feedback (HSF) encoder with optical sensing, supplying high-speed controllers with incremental and absolute data. Heat generated in the 093-size stator is removed by natural convection, eliminating external fans and reducing maintenance points. A centering diameter of 130 mm aligns the flange accurately on gearboxes or machine frames, supporting repeatable installation at up to 1000 m above mean sea level.

For precision applications, system accuracy is held within ± 0.5 angular minutes, aided by the relative position detection method and the balanced B-length rotor. Continuous duty is permitted from 0 to 40 °C ambient temperature, while storage temperatures from -20 to +80 °C help prevent transport damage. An integrated holding brake supplies 22.0 Nm of static torque to secure vertical axes when power is removed. The rectangular mounting interface follows a flange size of 140 / 150 mm, and a keyed shaft with a shaft seal prevents lubricant escape. The motor uses winding code 058 for the electrical characteristics expected by the connected controller.
