Product Description:

The MHD115A-058-PG0-BA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It combines a 115 frame size with an A-length housing to provide compact rotary motion for industrial automation axes that require precise position control. This arrangement suits applications that need repeatable positioning and stable speed control. A plain shaft, an integrated digital servo feedback encoder with absolute position tracking beyond 4096 revolutions, and a connector mounted on side B simplify integration with drive controllers and mechanical couplings.

This motor develops a continuous standstill torque of 32.0 Nm, allowing it to hold loads without external gearing. The enclosure carries a protection rating of IP65, so internal components remain sealed against dust and water jets during washdown or particulate processes. Mounting uses a square flange that measures 192 mm, while thermal energy is removed by natural convection, eliminating the need for forced air or liquid cooling. Stable performance is maintained within an operating ambient range of 0 to 40 °C, and within this window the optical measurement system provides continuous position data to the drive.

The mechanical interface is centered by a 180 mm pilot diameter, which aligns the stator precisely on a machine frame. Class F insulation supports winding temperatures up to 155 °C, and overall system accuracy is specified at ± 0.5 angular minutes for finely tuned motion profiles. Installation is permitted up to 1000 m above mean sea level without derating, and long-term storage is acceptable from -20 to +80 °C. The unit is supplied without a holding brake, so an external locking method is required when power is removed. A shaft seal is fitted to limit lubricant migration, and the feedback system is optical for high-resolution position detection. The stated storage range allows the motor to be kept out of service before installation.
