Product Description:

The MKE045B-144-KG0-KN is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It converts regulated current from a drive controller into precise mechanical torque, allowing coordinated motion in automated packaging, assembly, and material-handling stations. Its compact frame and closed-loop capability make it suitable for multi-axis systems where position accuracy and repeatable speed control are required. The motor is well suited for applications that need responsive starts, stable running speed, and accurate synchronization with neighboring axes.

Its wiring layout follows a top connection direction, so cable glands emerge upward and let the stator mount flush against a machine plate without requiring side clearance. The power interface is realized through a terminal box, giving screw-clamp terminations that accept field-installed conduit while preserving the housing ingress rating. For braking requirements, the unit is supplied without a holding brake, so any static load must be secured by external mechanical locks or drive torque. The stator carries winding code 144, which identifies the electrical characteristics used by compatible Rexroth drives for current regulation. A dedicated shaft seal sits behind the front bearing to limit lubricant escape and help prevent dust or coolant from entering the motor interior.

Mechanical coupling is handled by a plain shaft that transmits torque without keyways, reducing stress concentrations during reverse cycles. A machined frontal centering hole on the shaft face helps align the rotor with gearboxes or couplings during assembly. The DIN 332 compliant DS thread inside that bore accepts puller bolts for removal when service is required. Because the motor is classified as a servo motor for potentially explosive areas, it is intended for installations where controlled surface temperature and enclosed electrical parts are important during normal operation.
