Product Description:

The MHD115B-058-NG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for electrically commutated drive systems where rapid velocity changes and accurate positioning are routine. By coupling a permanent-magnet rotor to a drive controller, the unit supplies commanded torque to machine axes while returning high-resolution feedback. This makes it suitable for CNC equipment, pick-and-place gantries, packaging machinery, and other automated systems that require repeatable motion.

Its continuous standstill torque of 50.0 Nm allows the shaft to resist static loads without overheating. The IP65 housing helps protect internal components from dust and low-pressure water jets. Position information comes from a digital servo feedback (HSF) system that is scanned optically and sends relative data to the controller. Mechanical integration uses a flange circle of 192 mm and a 180 mm centering diameter, so the motor seats precisely against standardized drive ends. Heat generated by the stator is removed through liquid cooling, which supports continuous-duty operation. The plain shaft is delivered without a keyway, and the motor is supplied without a holding brake to reduce axial length.

Electrical endurance is supported by F-class insulation. The motor operates in ambient temperatures from 0 to 40 °C, while storage is permitted from -20 to 80 °C and installation altitude can reach 1000 m above mean sea level. The feedback chain has a system accuracy of ± 0.5 angular minutes, which supports precise interpolation moves and stable position control. Power cables exit through an output connector on side B, which can simplify routing in cabinets and machine frames. A shaft seal helps block ingress along the plain journal, and the selected frame and winding combination matches the electrical characteristics expected by compatible Indramat drives.
