Product Description:

The MHD115C-059-NG0-AA is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It transforms command signals from a drive controller into precisely metered rotary motion for positioning tooling, conveyors, or actuator stages in automated machinery. This role suits machine axes that require repeatable speed and position control during normal production.

At the mechanical core, the motor can deliver a continuous standstill torque of 70.0 Nm, allowing it to hold static loads during indexing cycles without overheating. Its enclosure carries an ingress rating of IP65, so internal windings remain protected from dust and low-pressure water jets when the machine operates on the factory floor. Heat generated by copper losses is dissipated through natural convection; this passive cooling method removes the need for external blowers and simplifies cabinet design. Rotor position is measured with Digital servo feedback (HSF), an optical sensing system that returns high-resolution incremental data to the drive for tight velocity and position loops. The resulting closed-loop precision is reinforced by a system accuracy of ± 0.5 angular minutes, limiting cumulative deviation over repetitive moves.

Additional construction features simplify integration. Its centering pilot diameter is 180 mm, and the square mounting flange spans 192 mm, providing a stable interface to gearboxes or direct-drive frames. Thermal integrity across production shifts is rated for ambient operation from 0 to 40 °C, while an insulation system classified as F withstands winding temperatures up to 155 °C before degradation. Installation is permitted up to 1000 m above mean sea level without derating, supporting use in elevated facilities. A plain shaft design and an output connector that exits toward side A streamline coupling and cable routing, and the absence of a holding brake lowers rotational inertia for axes that reverse frequently.
