Product Description:
The MKD090B-046-KP0-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Designed for closed-loop industrial automation, it converts drive controller commands into precisely regulated rotary motion for indexing tables, packaging lines, and material-handling axes. Its construction allows direct use in mid-frame machinery where stable position control and repeatable motion are required throughout normal production cycles. The motor is suited to applications that need accurate speed regulation, responsive torque delivery, and compact installation within a standardized industrial drive system.
Mechanical installation uses a centering diameter of 110 mm and a square flange measuring 140 mm. Power and feedback conductors exit on side B through a sealed connection box, which helps keep cable routing orderly and protects the connection area from external contamination. The keyed shaft includes a shaft seal, and the housing has an IP65 rating for resistance to dust and low-pressure water jets. At standstill, the motor delivers continuous torque of 12.0 Nm, and because it does not include a holding brake, any parked load must be supported by drive current or an external mechanical device. This layout supports mounting in enclosed machine sections where cable entry direction and shaft sealing matter for reliable operation.
Electrical and thermal characteristics describe the motor’s operating range. Winding code 046 matches the stator to compatible drive settings within the MKD motor family, while the B motor length and 090 frame size establish the physical stack used by this model. Insulation class F supports sustained winding temperature capability when the surrounding air remains within 0 to 40 °C. A resolver with an integrated encoder supplies absolute position data for more than 4096 revolutions, which allows the drive to retain position information across multiple turns. System precision is limited to ±8 angular minutes over the full mechanical span, making the motor appropriate for axes that need dependable rotary feedback and controlled positioning behavior.
