Product Description:

The MHD115A-058-NG1-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It combines a 115 frame size with motor length A for closed-loop motion on positioning axes, pick-and-place modules, and similar automated equipment. Designed for coordinated motion, it converts drive commands into controlled rotary movement for machines that require repeatable travel and stable speed control. Its digital servo feedback encoder works with the drive controller to provide precise relative position data during acceleration, deceleration, and dwell periods. This closed-loop arrangement helps the controller compare commanded and actual motion in real time so the axis can repeat the same path reliably.

This model provides a continuous standstill torque of 32.0 Nm and uses a holding brake rated at 70.0 Nm to keep the load in place when power is removed. Heat from continuous operation is removed by liquid cooling, allowing the motor to operate across an ambient range of 0 to 40 °C. The housing is sealed to IP65, and a shaft seal helps protect the plain shaft interface from fluid ingress. A 180 mm centering diameter aligns the 192 mm flange to adjoining machine parts, and the output connector routes the power lead on side A. The feedback system supports a system accuracy of ± 0.5 angular minutes, which is suitable for repeatable positioning tasks in automated machinery.

Electrical performance is set by winding code 058, and the winding system uses F-class insulation for industrial thermal duty. Installation is permitted up to 1000 m above sea level, and storage is permitted from -20 to +80 °C. The optical measurement method reduces wear because no mechanical sensor parts touch the rotor during operation. This arrangement lets the drive receive position information without contact-based sensing elements at the shaft. The compact housing supports use on dynamic machine axes where low moving mass is helpful.
