Product Description:
The MHD093B-058-PP1-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for industrial automation tasks that require controlled torque and accurate angular positioning, such as gantry axes, tool changers, and packaging stations. Motor size 093 and length code B set the overall envelope for medium-frame machinery, while the keyed shaft provides a positive mechanical interface for couplings or pulleys. This layout supports precise rotary motion where repeatable starts, stops, and direction changes are required during continuous machine operation.
At standstill, the unit supplies a continuous torque of 17.5 Nm, and insulation class F helps maintain winding temperature margin during prolonged duty. Heat is removed through liquid cooling channels in the housing, which supports steady thermal control under sustained load. The enclosure is rated IP65, helping protect internal components from dust and directed water. A centering diameter of 130 mm helps align the motor on the mounting face, and electrical pattern code 058 matches the stator arrangement to compatible Indramat drives. Feedback is produced by an integrated digital servo encoder that provides absolute position data over more than 4096 revolutions, and power enters through a connector on side A while a shaft seal helps protect the bearings from contamination.
A spring-applied holding brake develops 22.0 Nm so the load can remain stationary when the inverter is disabled. During motion, the closed-loop system maintains an accuracy of ±0.5 angular minutes, which supports applications that require consistent path control and repeatable positioning. The permitted ambient operating range is 0 to 40 °C, and operation is permitted at installation heights up to 1000 m above mean sea level. Storage from −20 °C to 80 °C helps avoid material stress when the motor is not in service. The mounting flange uses a bolt circle of 140 / 150 mm, allowing direct attachment to standardized gearboxes and machine frames.
