Product Description:

The MHD131D-024-PG0-BN is a three-phase servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop drive element, it converts electrical energy into regulated mechanical torque for positioning tasks in presses, gantries, and machine tools. It uses winding code 024 and is intended for operation with digital drives that control speed and position through the integrated feedback system. This arrangement lets the drive monitor rotor position continuously and correct motion errors during acceleration, deceleration, and holding tasks.

The motor has a 131 frame size with a D-length housing and mounts through a flange that measures 260 mm, while a 250 mm centering diameter helps keep the assembly aligned. Continuous stall torque reaches 160 Nm, and heat is removed through integrated liquid cooling channels so steady loads can be handled without overheating. The housing is rated IP65, and a shaft seal helps protect the plain output shaft area from dust and low-pressure water. When the optical measurement system is active, the motor can support system accuracy of ±0.5 angular minutes for precise motion. Permissible ambient temperature during operation is 0 to 40 °C, and higher temperatures require derating.

Position and speed data are provided by digital servo feedback with absolute (>4096 revolutions) resolution, allowing closed-loop control to start immediately after power-up. The windings use Class F insulation, which supports temperatures up to 155 °C and suits the motor's thermal design. The optical feedback system supports stable speed regulation as well as repeatable positioning on axes that must return to known locations. The motor is supplied without a holding brake, and its power leads exit on side B through an output connector. Storage is permissible from -20 to +80 °C, and installation is approved up to 1000 m above mean sea level.
