Product Description:

The MHD112A-058 is a three-phase permanent-magnet servo motor engineered by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. In automated machinery, this model converts commanded drive currents into precise rotational motion for axes that must accelerate quickly, stop accurately, and hold position under static load. When paired with compatible Indramat digital drives, the motor acts as the electromechanical interface between the controller and the mechanical transmission. This arrangement supports repeatable motion in packaging lines, printing presses, and material-handling systems where low position error is important.

Its mechanical mounting surfaces follow IEC square-flange conventions. The centering pilot diameter is 130 mm, a tolerance feature that helps align the stator face concentrically with gearboxes or machine frames. A square flange dimension of 192 mm sets bolt pattern spacing and supports interchange with other 112-frame units. Under continuous stall conditions, the motor develops 15.0 Nm of torque, allowing the axis to resist process forces without overheating. Frame designation 112 identifies the motor size used for compatible shaft and bearing sets. Winding code 058 indicates the copper fill and turns ratio chosen for voltage constants that suit common 300 V class drive inverters.

Compactness is addressed by length code A, the shortest stack available for this frame, which reduces axial space while keeping the same mounting interface. This short housing helps when the machine layout leaves limited installation depth behind the mounting face. It can be used on indexing tables, feed axes, and similar mechanisms that need repeatable starts and stops within a compact envelope. The permanent-magnet design also supports quick response during speed changes and positioning moves.
