Product Description:

The MHD115C-058 is an AC servo motor engineered by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It provides closed-loop rotary motion in automated packaging lines, gantry axes, and general-purpose positioning stages where repeatable speed and torque control are important. By combining permanent-magnet excitation with internal feedback devices, the unit converts commands from a drive controller into precise shaft movement, allowing industrial machinery to synchronize multiple axes, hold load positions, and follow dynamic motion profiles. This operating style is useful on axes that must start, stop, reverse direction, and track commanded positions with minimal settling error.

The front flange uses a centering pilot of 180 mm, which aligns the motor concentrically to machine frames or gearheads and helps limit radial runout. Surrounding that pilot, the mounting flange measures 192 mm for rigid attachment. Frame code 115 identifies the motor size, while length identifier C indicates the third axial stack in this frame. Electrical behavior is set by winding code 058, which matches the motor to compatible Rexroth inverters through its voltage constant, rated current, and back EMF. These dimensions are useful when checking coupling alignment, flange fit, and available installation space in existing machine layouts.

The motor has a continuous standstill torque of 70.0 Nm, so it can maintain twisting force at zero speed without exceeding thermal limits. Because it is a servo motor, the drive can use feedback-controlled operation for load holding, small indexing moves, and stable positioning during speed changes. This helps the motor manage repeated start-and-stop cycles without losing positional accuracy when the load varies. It is well suited for applications that need steady holding force at standstill as well as smooth motion during short travel commands.
