Product Description:
The MHD095A-058-PG1-RN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It combines an integrated absolute encoder with winding code 058 to provide closed-loop position control and stable speed regulation in automated machinery. The unit has a plain shaft with a shaft seal for fluid-tight coupling to gearboxes or belt drives, while a power connector on the right side helps simplify cable routing in multi-axis systems.
This motor develops a continuous standstill torque of 12.0 Nm, giving stable holding force for presses, indexers, and tool heads that remain energized for long periods. The housing is rated to IP65, so dust and low-pressure water jets will not impair operation on the production floor. A flange circle of 140 / 150 mm aligns with standard IEC mounting patterns, and a centering diameter of 130 mm keeps the stator concentric with driven equipment. Heat is removed through liquid cooling, allowing the windings to sustain torque in compact enclosures. For dynamic stops or vertical axes, the integrated holding brake supplies 22.0 Nm of static torque. Insulation class F permits winding temperatures up to 155 °C, and optical measurement inside the encoder helps maintain feedback integrity at high speeds.
During storage, the motor tolerates ambient temperatures from -20 to +80 °C. Continuous operation is limited to 0 to 40 °C to preserve lubricant viscosity and magnetic alignment. System accuracy is held within ± 0.5 angular minutes, so repeatability remains stable even when the installation height approaches 1000 m above mean sea level. Position data are retained through power cycles because the encoder uses Absolute (>4096 revolutions) multi-turn tracking, which avoids a homing routine after each shutdown. A motor length code A and size code 095 complete the dimensional envelope for installations that must match existing mechanical platforms.
