Product Description:

The MHD093C-058-NG0-RN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop rotary actuator, it provides position and velocity control to automated machinery through relative position detection and digital feedback. The feedback system allows the drive to monitor rotor movement continuously and correct deviations during operation. This supports accurate motion on machine axes that require repeatable speed regulation and controlled acceleration. The unit's plain shaft interfaces directly with driven components, while the integrated shaft seal limits fluid ingress at the coupling.

This motor can generate 23.0 Nm of continuous standstill torque, enough to hold loads without external gearing. A protection level of IP65 shields the housing against dust and low-pressure water jets, and the stator jacket uses liquid cooling to remove heat without enlarging the frame. Position data is captured by a digital servo feedback (HSF) encoder that uses an optical measurement method and provides system accuracy of ±0.5 angular minutes. Mechanical centering is simplified by the 130 mm centering diameter and the 140/150 mm flange pattern. Power is delivered through a right-side power connector, and the motor is supplied without a holding brake.

The motor remains thermally stable within an operating ambient of 0 to 40 °C, while safe storage extends from -20 to +80 °C. The operating range applies during normal use, while the storage range covers powered-down handling and transport. The windings use class F insulation, which supports elevated internal temperatures without degrading the enamel. Electrical characteristics follow winding code 058, and the motor uses size 093 with length code C. Installation is permitted up to 1000 m above mean sea level. Relative position detection supports homing sequences at startup, and optical feedback helps maintain fine interpolation when load dynamics vary during duty cycles.
