Product Description:
The MHD093B-058-NP0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Used in industrial automation, the motor converts drive commands from a compatible controller into precise rotary motion for positioning tasks in packaging equipment, handling systems, and other machine axes. Liquid channels integrated into the stator jacket remove heat, allowing the unit to sustain rated output without auxiliary fans. Its digital servo feedback encoder supplies high-speed position signals to the drive, and the lack of a holding brake reduces inertial load where passive shaft locking is unnecessary.
The motor delivers a continuous standstill torque of 17.5 Nm, supporting axis loads that must remain energized for long dwell periods. An enclosure rating of IP65 blocks dust and low-pressure water jets, helping protect the stator windings from contamination during operation. A centering diameter of 130 mm aligns the flange face concentrically with gearboxes or machine plates, while the 140/150 mm flange pattern handles axial clamping forces. Heat is dissipated through liquid cooling, which helps keep frame temperature within the limits of Insulation Class F. The B length code provides a balance between power density and installation depth.
High-resolution optical measurement inside the encoder yields a system accuracy of ± 0.5 angular minutes, which supports precise positioning in packaging or machining centers. A keyed shaft transmits torque without slip, and an integral shaft seal helps prevent coolant ingress at the output end. The rated operating envelope spans 0 to 40 °C, while components can be stored from -20 to 80 °C. Winding code 058 corresponds to the resistance and inductance values used with the designated drive series. Power is routed through an output connector on side A, letting cable runs exit in one direction for orderly panel layouts. Relative position detection combines with the high-speed feedback protocol to maintain control loop stability up to 1000 m above mean sea level.
