Product Description:

The MHD115A-058-PG1-AN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is a permanent-magnet synchronous motor for closed-loop rotary motion on industrial automation axes in packaging machines, transfer lines, and handling systems. An integrated digital encoder provides electrical commutation and precise velocity data to the drive controller, allowing the motor to follow complex motion profiles with tight tolerance. This combination supports accurate acceleration, controlled deceleration, and stable positioning during repeated machine cycles.

Its centering diameter measures 180 mm, aligning the stator housing precisely with the gearbox or machine frame. Under rated current, the motor delivers a steady standstill torque of 32.0 Nm, making it suitable for axes that must hold position against constant load during operation. A square mounting flange with an edge length of 192 mm provides ISO-pattern bolt holes for rigid attachment. Heat generated in the windings is removed by liquid cooling, which supports higher continuous power density than natural-convection designs of the same size. The electromagnetic package uses winding code 058, which indicates the winding arrangement used for this motor.

The integrated holding brake supplies 70.0 Nm of static torque during power-off conditions, helping prevent vertical loads from drifting. Motion is transferred through a plain shaft, which avoids keyway stress concentrations when used with a clamping hub. An absolute feedback channel with more than 4096 revolutions supports multiturn position recovery after shutdown, so the controller can retain axis position information across power cycles. The motor's power leads exit the housing on side A, and a shaft seal helps block coolant splash and dust at the rotating interface. This cable orientation can also simplify routing when the machine layout places connectors along that side of the axis.
