Product Description:

The MKE045B-144-GP0-KN is a servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for use in hazardous locations, it delivers closed-loop rotary motion in automated valves, mixers, or indexing tables placed inside paint booths, chemical lines, and other potentially explosive environments. By combining flameproof construction with synchronous motor dynamics, the unit supplies constant torque at commanded speed so that drives can maintain precise positioning without drift. This supports stable motion where repeatable speed and position are required under demanding operating conditions.

All electrical terminations exit from the housing on the top side, protecting cables from floor washdowns or debris. Power conductors are routed through a cast-metal terminal box that accepts threaded glands, providing strain relief while keeping the internal compartment gas-tight. The motor is supplied without a holding brake; therefore, mechanical locking or drive torque must secure vertical loads during power loss. A splined coupling is unnecessary because the output shaft includes a precision-ground keyway that matches standard hubs. To block vapor migration toward the front bearing, a shaft seal is fitted between the rotor journal and end shield. This layout also keeps connection points accessible from above and helps separate wiring from nearby moving machine parts.

The winding code 144 corresponds to the number of series turns and results in voltage constants suited for 230 V class inverters, allowing full torque delivery at low stator current. Accurate coupling alignment is simplified by the standardized DIN 6885 key profile, which supports interchangeable fit with metric pulleys across multiple assemblies. Because the unit is certified as a servo motor for potentially explosive areas, its surface temperature remains within T4 limits when operated inside appropriately rated enclosures. The motor can also be paired with flameproof gear stages in systems that require documented hazardous-area compatibility.
