Product Description:

The MHD093A-058-NP1-BA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is applied in automation lines where closed-loop rotary motion is required for positioning or velocity control. The motor’s 093 frame and A-length housing accommodate winding code 058, providing the electrical constants required by the associated drive. Digital servo feedback in high-speed format provides relative position data to the controller, and a keyed shaft transmits torque directly into couplings or gearboxes without slip.

At standstill, the motor delivers 12.0 Nm of continuous torque, enabling stable holding force during low-speed processes. Radial loads are centered against a 130 mm pilot diameter, and the mounting flange spans 140 / 150 mm to fit standard machinery patterns. Environmental ingress is blocked by an IP65 enclosure, so washdown or dusty areas do not affect internal windings. Motion accuracy is maintained within ± 0.5 angular minutes, and this precision results from the optical measurement method combined with relative position detection. A spring-applied holding brake supplies 22.0 Nm to keep the axis locked when power is removed, allowing safe load retention on vertical or indexing stations.

The unit operates between 0 to 40 °C with natural convection cooling and may be stored from -20 to +80 °C without degradation of magnets or insulation. Class F materials permit winding temperatures up to 155 °C during duty cycles, while an internal shaft seal prevents lubricant escape and protects the feedback scanner. Installation is permitted up to 1000 m above mean sea level, and cabling exits on side B through an output connector that simplifies cable routing. Power conductors, encoder lines, and the keyed shaft are aligned by the 093 size code to maintain mechanical compatibility across the MHD family.
