Product Description:

The MKD090B-058-KP2-KN is a synchronous servo motor from the MKD Synchronous Motors series by Bosch Rexroth Indramat. It is used as a rotary actuator for CNC axes, packaging machinery, and other automated equipment that requires closed-loop speed and position control. Integrated resolver feedback works with compatible drives to produce vector-controlled torque, and the sealed housing allows direct mounting on production machinery. This arrangement supports stable motion control during indexing, contouring, and speed-regulated operation. Its winding code, mounting arrangement, and electrical interface follow the general format used across the MKD range.

The motor uses a square flange of 140 mm and a locating pilot of 110 mm, which supports accurate alignment on the machine face. Electrical power and feedback leads exit on Side B through a sealed connection box, keeping cable routing away from the driven shaft and helping protect the terminals. Rated continuous torque is 12.0 Nm, which allows steady load handling and low-speed motion without excessive heat buildup. The housing is rated IP65, so dust and low-pressure water exposure are kept away from internal components during normal machine use. Motion feedback is provided by resolver feedback, supporting closed-loop positioning with an accuracy of ±8 angular minutes.

Operation is permitted in ambient temperatures of 0–40 °C, and the windings use class F insulation for thermal durability during cyclic duty. The rotor has a shaft with a keyway for positive torque transfer to couplings, while the fitted shaft seal helps keep contaminants away from the bearing area. Motor length B gives the housing a moderate axial profile, and frame size 090 places it in a mid-size format suited to many machine axes. Winding code 058 corresponds to the electrical characteristics expected by the matching drive. These features support repeated starts, stops, and speed changes in automated motion systems.
