Product Description:

The MKD090B-058-KG1-KN is a servo motor manufactured by Bosch Rexroth Indramat in the MKD Synchronous Motors series. Designed for closed-loop position and speed control on automated axes, the unit converts drive output current into mechanical rotation for gantries, packaging equipment, and material-handling lines. Its integrated resolver supports accurate shaft-angle control and repeatable motion in multi-axis systems. The motor is suited for applications that require consistent acceleration, controlled speed changes, and reliable positioning through repeated operating cycles.

The motor’s centering diameter is 110 mm, providing a locating surface that aligns the stator housing within a machine frame. Power, feedback, and ground conductors exit on Side B, and the connection box encloses these terminals so wiring remains accessible without removing the motor. At stall, it produces 12.0 Nm of continuous torque under rated cooling and winding temperature conditions. Rotor position is measured by resolver feedback with an integrated encoder, supplying analog sine-cosine signals that the drive converts into digital position values. Size code 090 and length code B indicate the motor’s core dimensions and overall housing length.

For static holding or emergency stops, the motor includes a holding brake that generates 11 Nm of torque when 24 V is applied, and the brake must be released before commanded motion begins. The feedback system supports absolute position over more than 4096 revolutions, which helps the control system retain position reference after power cycling. The rotor drives the load through a plain shaft, and a shaft seal is installed to help limit the ingress of coolant or dust. Winding code 058 identifies the electrical characteristics matched to the compatible drive. This arrangement supports stable motor operation in machines that depend on repeatable stopping, starting, and position recovery.
