Product Description:

The MHD090B-058-PP0-UP is a servo motor manufactured by Bosch Rexroth Indramat as a member of the MHD Synchronous Motors series. This servo motor converts commanded electrical energy into accurately regulated rotary motion, letting automation controllers position mechanical loads with repeatable precision. It is used in material-handling axes, packaging stations, and other motion tasks that need closed-loop speed and position control. This supports accurate movement in indexing, transfer, and servo-driven feed systems where repeatability is important.

The motor uses a centering diameter of 110 mm and a square flange measuring 140 mm, which simplifies coaxial mounting on gearboxes or machine frames. A continuous standstill torque of 12.0 Nm allows the shaft to support static loads without overheating, while natural convection cooling removes heat during operation. Its enclosure carries a protection rating of IP65, which blocks dust ingress and water jets from internal components. The motor also uses F-class insulation and winding code 058 for this frame size. Motion feedback is generated through an optical encoder with a deviation limit of ± 0.5 angular minutes, giving the controller high-resolution data for precise velocity and position control. Power and feedback connectors can be rotated through 270° for more flexible cable routing in compact installations.

Environmental tolerances support storage from −20 to +80 °C and continuous operation from 0 to 40 °C, which covers normal shutdown and production conditions. The motor provides absolute position over more than 4096 revolutions, so homing routines are unnecessary after power cycles. A keyed shaft transmits torque without slip, and an integrated shaft seal helps keep oil or coolant out of the bearing chamber. The unit is delivered without a holding brake and can be installed up to 1000 m above mean sea level without derating.
