Product Description:
The MHD095C-058-PG1-RN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Its 095 frame, C length, and 058 winding code suit medium-inertia machinery that requires precise point-to-point motion. By integrating an absolute optical encoder, the unit supplies real-time position data to the drive controller so it can support closed-loop motion in automated packaging, metal-cutting, or handling stations. This motor type is well suited for servo axes that require repeatable acceleration, controlled deceleration, and stable feedback during frequent start-stop cycles.
The motor produces a continuous standstill torque of 23.0 Nm, allowing sustained holding or low-speed cutting without overheating. A square flange of 140 / 150 mm provides standardized mounting to gearboxes or inline couplings, and the housing has an IP65 rating that helps keep out shop dust and water jets. Internal liquid cooling extracts heat from the stator jacket so the class F windings can remain below their thermal limit at high current density. Because heat is carried away through a closed coolant path, the motor can support continuous duty in compact machine layouts where ambient airflow is limited. Electrical power enters through a right-side power connector, and the plain shaft includes a factory-installed shaft seal to help prevent lubricant migration. The centering diameter, motor size, and flange interface support concentric alignment, and rated performance is maintained at installation altitudes up to 1000 m above sea level.
A holding brake delivers 22.0 Nm of torque to secure vertical loads when the drive is disabled, and the encoder reports positions with a system accuracy of ± 0.5 angular minutes. This arrangement is useful on axes where the load must remain stationary after drive power is removed. The centering pilot uses a 130 mm fit, which helps seat the motor accurately on the machine frame. Rated operation is permitted from 0 to 40 °C, while storage from −20 to 80 °C helps protect insulation during downtime. Optical scanning, combined with an Absolute (>4096 revolutions) feedback range, allows the drive to retain position information after power is restored without a separate homing cycle.
