Product Description:

The MHD093A-058-NP0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for industrial automation, it converts drive current into controlled rotary motion for positioning tables, gantry axes, and tool spindles. Relative position detection and an optical measurement system allow the controller to close high-speed loops without external sensors, giving the machine builder a compact motion element.

The motor delivers a continuous standstill torque of 12.0 Nm, which is the load it can support continuously while remaining within its thermal envelope. A sealing grade of IP65 blocks dust and low-pressure water jets, so the housing is suitable for production areas that require washdown protection. Rotor angle is transmitted through digital servo feedback (HSF), enabling high-resolution commutation without a secondary encoder. Heat is removed by natural convection, so no fan or liquid cooling circuit is required. A centering pilot diameter of 130 mm aligns the flange precisely to gearboxes or mounting plates, and the motor is supplied without a holding brake to keep inertial mass low.

Motion accuracy reaches ± 0.5 angular minutes, supporting finely tuned contouring cuts and repeatable indexing. The motor sustains continuous duty in ambient temperatures from 0 to 40 °C, with storage permitted from -20 to +80 °C and operation allowed up to 1000 m above mean sea level. A hardened keyed shaft transfers torque and is protected by an integral shaft seal. The square mounting flange spans 140 / 150 mm to match standard IEC frames. Additional details include insulation class F windings, winding code 058, motor length A, motor size 093, and a power lead that exits toward side A through an output connector.
