Product Description:

Bosch Rexroth Indramat's MHD115B-035-NG0-AA belongs to the MHD Synchronous Motors series and serves as a servo motor for precise rotary positioning in automated machinery. The unit combines motor size 115 with the B length code to balance torque capacity and overall package length. It supports relative position detection, allowing the drive to return repeatedly to the same mechanical reference during cyclic motion. This layout suits packaging, handling, and machine-tool axes that require repeatable starts, stops, and directional changes under closed-loop control. During installation, the power connector faces side A, which helps route cables toward the cabinet and keeps the connection area easy to access.

At standstill, the motor supplies a continuous torque of 50.0 Nm, allowing indexing tables or presses to hold load without thermal overload. The housing has an IP65 rating, which helps keep dust and low-pressure water jets out of the stator enclosure. Position data are generated by a digital servo feedback (HSF) encoder that uses an optical measurement method for high-resolution signals, and a flange diameter of 192 mm with a centering diameter of 180 mm helps align the motor on standard machine frames. Heat leaves the stator through natural convection, so no fan is required and the sealed motor profile is maintained. Class F insulation withstands the resulting temperature rise during normal operation.

The motor operates in ambient temperatures from 0 °C to 40 °C, and it can be stored or transported in conditions from -20 to +80 °C without harming the windings. Installation is permitted up to 1000 m above mean sea level, which suits most industrial plant floors. A plain shaft with a shaft seal helps protect the bearing region from contaminants, while the lack of a holding brake means stopping or safety functions must be handled by external equipment. Motion accuracy remains within ± 0.5 angular minutes, supporting repeatable positioning in applications that require controlled indexing and stable servo response.
