Product Description:

The MHD093A-058-PP1-AA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In industrial automation, this motor supplies closed-loop rotary motion to packaging stations, handling robots, and gantry axes, delivering regulated torque through its keyed shaft while its absolute encoder feeds position data back to the drive electronics. Its synchronous design supports accurate speed regulation and repeatable positioning during indexing, coordinated motion, and frequent direction changes. This model uses winding code 058 and belongs to motor size 093 with compact length code A.

A centering diameter of 130 mm aligns the 140 / 150 mm flange to the machine frame, and the power conductors exit on side A through an output connector that simplifies cabinet routing. Continuous stall torque reaches 12.0 Nm, sustained by a housing that is cooled by natural convection. The enclosure carries a protection rating of IP65, so it resists dust ingress and water jets within an operating ambient of 0 to 40 °C. Class F winding insulation tolerates elevated copper temperatures, and installation is permitted up to 1000 m above mean sea level. Optical measurement inside the integrated encoder supports stable feedback, while storage temperatures can range from −20 to +80 °C without damaging magnets or bearings.

A holding brake rated at 22.0 Nm keeps the rotor locked when power is removed, and a shaft seal is fitted to limit lubricant migration along the motor shaft. Feedback is provided by a digital servo feedback system that captures multi-turn absolute position data over more than 4096 revolutions. This arrangement yields a system accuracy of ± 0.5 angular minutes, supporting precise indexing without external encoders. The multi-turn feedback helps the control system retain shaft position through repeated turns, which is useful on axes that cannot be re-homed before every operating cycle.
