Product Description:
The MKE045B-144-KG1-KN is a brushless AC servo motor produced by Bosch Rexroth Indramat and supplied in the MKE Synchronous Motors series. Within automated assembly, it turns drive current into precise rotary motion that positions tooling, feeders, and conveyor rollers under closed-loop control. The slim 45 mm frame fits multi-axis gantries where fast acceleration and repeatable torque are required. Paired with an IndraDrive amplifier, the motor supports accurate speed regulation and helps maintain cycle times on pick-and-place stations, packaging modules, and light material-handling axes.
Electrical behavior is set by winding code 144, which indicates the back EMF and compatible inverter voltage. Cables exit through the top of the housing, and this connection direction keeps the sealing surfaces clear when the motor is bolted to a machine bed. Conductors land in a cast-aluminum terminal box, where screw clamps separate power, brake, and feedback lines. A spring-applied mechanism secures the rotor because the unit is equipped with a holding brake, allowing vertical axes to remain fixed during power loss. Contaminant ingress is limited by a shaft seal that also retains bearing grease, extending service intervals in continuous-duty applications.
The device is classified as a servo motor for use in potentially explosive areas, so it can operate in zones that contain ignitable mixtures. Coupling is straightforward because the output uses a plain shaft that accepts clamp hubs or bellows couplings without additional machining. For extraction, a DIN 332-compliant DS thread at the shaft face accepts an ejector screw that pushes the rotor from a tight-fit hub. Precise axial alignment during installation is provided by a frontal centering hole, which serves as a datum when dial-indicating pulleys, gears, or timing wheels.
