Product Description:

The MHD115A-035-PG1-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop actuator, it converts drive current into controlled rotary motion for positioning tasks in automated machinery, material-handling axes, and packaging stations. This motor is intended for applications that require coordinated motion, repeatable positioning, and stable speed control under varying load conditions. It uses a plain shaft with an integrated shaft seal, and its digital servo feedback combines an absolute encoder with optical measurement to report position over more than 4096 revolutions.

The motor has a centering diameter of 180 mm and a flange size of 192 mm, which support accurate mounting on standard machine interfaces. It delivers a continuous standstill torque of 32.0 Nm when energized, allowing the axis to hold load without stalling. The housing is rated IP65, which helps protect internal components from dust and water jets. Cooling is provided by natural convection, so no external blower is required. Insulation class F supports the winding temperature limits associated with this cooling method. Power is connected through an output connector on side A, and the motor uses size 115, motor length A, and winding code 035.

The factory-mounted holding brake provides 70.0 Nm to secure vertical or suspended loads during power loss. The encoder system accuracy is ± 0.5 angular minutes, which supports precise positioning at low speed. The motor can operate in ambient temperatures from 0 to 40 °C. Storage and transport are allowed from -20 to +80 °C without damage. Installation is permitted up to 1000 m above mean sea level, and the absolute feedback system allows multi-turn position tracking without relying on a fresh reference after every shaft rotation.
