Product Description:

The MHD093A-058-PG1-BA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop industrial axes where precise rotary motion and consistent feedback are required for coordinated automation tasks. The integrated absolute encoder stores position information over more than 4096 revolutions, and the optical measurement method supports high-resolution feedback to the drive controller. By combining a plain shaft design with an output connector on side B, the unit fits machines that restrict cable-routing space and require a compact motor connection layout.

At standstill, the motor can continuously supply 12.0 Nm of torque, allowing it to hold or slowly index loads without overheating. The enclosure is rated to IP65, so dust ingress is prevented and low-pressure water jets do not affect internal components. The specified operating ambient of 0 to 40 °C suits most control-cabinet environments and matches the motor’s cooling arrangement. During emergency stops, the integrated brake delivers 22.0 Nm of holding torque to keep vertical or suspended loads stationary. Position repeatability is supported by a system accuracy of ± 0.5 angular minutes, which helps limit the difference between commanded and actual shaft angles during repeated moves.

A centering diameter of 130 mm mates the housing to standard IEC flanges sized 140 or 150 mm, and the plain shaft simplifies coupling to clamping hubs or shrink discs. Class F insulation withstands winding temperatures up to 155 °C, supporting reliable operation within the motor’s thermal limits. Heat is removed by natural convection, eliminating the need for external blowers and simplifying machine layout. A shaft seal helps block lubricant escape and helps limit contaminant entry at the output end. The motor also uses digital servo feedback for closed-loop position control, and storage from -20 to +80 °C helps protect the unit during transport or long-term storage.
