Product Description:

The MKD090B-046-KG0-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary actuator for industrial automation, it converts drive current into controlled mechanical torque and speed for positioning tasks on packaging stations, material-handling axes, and general motion platforms. Its operating role is to provide repeatable motion where the drive must regulate both speed and shaft position during changing load conditions. This makes the motor suitable for automated equipment that depends on accurate starts, stops, and directional changes throughout normal cycle operation.

This model delivers 12.0 Nm of continuous standstill torque, allowing moderate static load support without thermal overload. A flange size of 140 mm mates directly to gearboxes or machine frames, while the centering diameter of 110 mm keeps the housing aligned with mounting hardware. Winding code 046 identifies the electrical winding used by compatible drive controllers. Rotor angle and velocity are monitored through resolver feedback, which provides analog sine-cosine signals for closed-loop control. The motor has size code 090 and frame length B, placing it in a mid-frame format that balances inertia and output capacity. It is supplied without a holding brake, so position during power loss must be maintained by external mechanics or drive-generated torque. The plain shaft supports direct coupling to suitable hubs or clamp collars.

Cabling is routed on Side B through a sealed connection box, which helps protect terminations and keeps wiring contained at the motor body. The output end includes a shaft seal to limit the entry of dust or coolant during machine operation. Multiturn position retention is available through absolute (>4096 revs) feedback, so the axis can retain position information across power cycles without a homing routine. This combination of sealed cable routing and protected shaft output supports use in industrial environments where stable feedback and guarded mechanical interfaces are important. The feedback arrangement also helps the connected drive maintain precise motion control over long operating periods.
