Product Description:

The MKD090B-058-GG1-KN is a servo motor produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for industrial automation, the unit supplies controlled torque and speed so that packaging lines, robotic joints, and material-handling systems can follow command profiles with minimal position error. By combining a permanent-magnet rotor with electronic commutation, the motor provides synchronized motion for multi-axis drives in CNC and assembly equipment. This makes it suitable for feed axes and indexing tasks that must maintain coordinated motion with neighboring axes.

Mechanical mounting uses a centering diameter of 110 mm and a square flange that measures 140 mm, allowing direct coupling to gearboxes or machine frames without adapters. The rotor can deliver a continuous standstill torque of 12.0 Nm, and an integrated brake supplies 11 Nm of holding torque to secure vertical loads when power is removed. The motor uses winding code 058, which matches the electrical characteristics expected by compatible Rexroth drives. Position signals are generated by resolver feedback, so the drive receives analog sine-cosine information that remains stable in high-temperature and high-vibration conditions. The flange arrangement also helps maintain accurate shaft alignment after repeated machine cycles.

Field wiring is routed to the rear because the power and sensor terminals face Side B inside a sealed connection box, helping keep cable runs organized in tight cabinets. Output torque is transferred through a plain shaft fitted with a lip seal that helps block dust and coolant ingress. Relative position detection is the default operating mode, so the drive establishes an electrical zero at startup before normal motion begins. The motor size 090 with housing length code B gives the unit a compact footprint while still leaving room for the connector hardware and brake assembly. The sealed connection area also reduces exposure of terminals to debris inside the machine enclosure.
