Product Description:

The MKD090B-058-KP0-KS is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It is a servo motor that works with Rexroth drive controllers. The unit supplies repeatable torque and speed profiles for packaging stations, pick-and-place modules, and other computer-controlled machinery that depends on stable motion control during repeated cycles.

During continuous standstill, the motor can deliver 12.0 Nm of torque, which is available for static holding or slow-speed indexing without overheating. A square 140 mm flange allows mounting on standardized mechanical interfaces, and feedback is provided by resolver feedback with integrated encoder so the drive can track rotor position through power cycles. The inherent accuracy is limited to ±8 angular minutes, which suits applications that need moderate precision and fast recovery after disturbances. The enclosure is rated IP65, protecting internal parts from dust and low-pressure water jets. A Class F insulation system supports thermal performance, the 058 winding is used with motor length B, wiring is routed through a connection box, there is no holding brake, a shaft seal helps prevent lubricant migration into the feedback cavity, and absolute position reporting beyond 4096 revolutions supports multi-turn homing routines.

A 110 mm centering diameter aligns the motor accurately during installation. Power and feedback leads exit on Side B, which can help clear adjacent modules in compact machine frames. The motor accepts ambient temperatures from 0–40 °C without derating, and a shaft with keyway transfers torque to pulleys or couplings while helping prevent slip under cyclic loading. Size code 090 balances rotor inertia with dynamic response so the axis can accelerate quickly while staying within the permitted system precision.
