Product Description:

The MHD115C-035-PG0-AA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a size 115 motor with length C, it serves as a direct drive element for positioning axes and cyclic processes in industrial automation. By converting electrical power from the drive controller into controlled rotary motion, the device provides repeatable torque through its plain shaft so machine tools, handling stages, and packaging equipment can maintain commanded speed and position accuracy.

The motor supplies a continuous standstill torque of 70.0 Nm, giving axes steady holding capability under load. Its housing carries a protection rating of IP65, so dust and low-pressure water jets do not reach internal windings. Mounting is guided by a 180 mm centering diameter and a flange that measures 192 mm across. Heat produced by the stator is removed through natural convection, a passive method that avoids external fans. The insulation system is graded for Class F temperatures, supporting winding reliability at elevated thermal conditions. Operation is permitted from 0 °C to 40 °C ambient, and the design omits a holding brake, relying on drive-based torque for static positioning. Power and feedback conductors exit on side A through an output connector, and a shaft seal helps prevent lubrication escape along the plain shaft.

Long-term accuracy is maintained by digital servo feedback that uses an optical measurement method, and the system delivers a positional deviation no greater than ± 0.5 angular minutes. Because the feedback is absolute (>4096 revolutions), homing routines can be skipped after power cycles. The stator winding code 035 matches drive controllers in the 300 V nominal class and indicates the electrical resistance and inductance values used by the motor. Storage temperatures from -20 °C to +80 °C are permitted, and installation is allowed up to 1000 m above mean sea level without derating.
