Product Description:
The MKD090B-058-KP1-KN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Designed for industrial automation, it converts drive power into precise rotary motion for indexing tables, pick-and-place axes, and other closed-loop positioning tasks. The B length construction keeps the stator package short enough for tight mounting spaces, while the 090 frame gives the electromagnetic core the cross-section needed for stable torque density. This combination supports responsive motion on machines that need repeatable positioning without using an oversized motor body.
At standstill, the motor can deliver 12.0 Nm of continuous torque, allowing medium-load axes to hold position without additional cooling. Its centering diameter measures 110 mm, and the square mounting flange spans 140 mm, letting the housing seat accurately against standard gearheads. Power, encoder, and brake leads exit on Side B, and each conductor terminates inside a sealed connection box that protects the electrical interfaces from contamination. These mechanical and wiring dimensions shape the installation envelope and help maintain orderly cable routing in compact machines. Thermal conduction through the stator housing and flange allows rated operation without forced cooling in most factory environments.
Load security is provided by a holding brake rated at 11 Nm, preventing drift when the axis is powered down. Precise motion feedback comes from a resolver feedback sensor with an integrated encoder that offers absolute measurement for more than 4096 revolutions. The output shaft uses a shaft with keyway profile for slip-free coupling, and a shaft seal blocks coolant or dust from entering the bearing chamber. Electrical characteristics are matched to winding code 058, and the B length with the 090 frame supports high cycle rates with low inertia. This layout is well suited to repeated starts and stops where stable feedback, secure torque transmission, and protected bearings are important.
