Main Features and Advantages

High dynamic performance and precision: The Indramat SP100-MF1-10​ is engineered for outstanding motion control. Its permanent magnet rotor design provides high torque density, meaning it delivers significant torque relative to its frame size. This, combined with low rotor inertia, enables extremely high acceleration and deceleration rates, allowing machinery to achieve shorter cycle times. The integrated high-resolution feedback device, typically a robust encoder, provides precise commutation and accurate real-time position data to the drive, ensuring exceptional velocity stability and repeatable positioning accuracy. This makes the 090A-0-RD-2-C​ servo motor ideal for contouring, indexing, and synchronous applications.Robust construction and reliability: Built for the harsh industrial environment, the SP100-MF1-10​ features a rugged housing, high-quality bearings, and a high-grade magnet system. The standard IP65 protection rating shields the motor from dust and water jets, ensuring reliable operation in demanding conditions like woodworking, packaging, or automotive assembly. The use of Class F insulation allows the motor to handle higher operating temperatures, contributing to a long service life and consistent performance. The design emphasizes low maintenance, with no brushes to wear out, translating to reduced downtime and lower total cost of ownership.Seamless system integration: As part of the proven Indramat (now Bosch Rexroth) motion control ecosystem, the 090A-0-RD-2-C​ is designed for perfect compatibility with a wide range of Indramat servo drives, such as the DKC/DDS series. The motor’s standardized mechanical interface and connector system simplify mechanical mounting and electrical connection. The well-documented parameters and tuning characteristics allow for quick and optimal commissioning when paired with the correct drive, ensuring the servo axis performs at its peak efficiency and responsiveness from the start.
