Product Description:

The MKE037B-144-GG0-BUNN is a servo motor produced by Bosch Rexroth Indramat and placed in the MKE Synchronous Motors series. It is classified as a servo motor for potentially explosive areas, so its mechanical and electrical interfaces are configured for use inside paint booths, mixing vessels, and other Zone 1 installations. When coupled to a matched drive, the motor supplies precise torque and speed feedback, allowing automated equipment in hazardous-duty automation cells to position loads, meter material flow, or align tooling without introducing ignition risks.

Environmental protection is provided by an IP65 enclosure, meaning dust ingress is prevented and water jets cannot reach live parts during washdown procedures. Thermal endurance relies on class 155 (F) insulation, so the winding system can tolerate continuous temperatures up to 155 °C before aging accelerates. The motor operates within an ambient range of 0 to +40 °C; outside this window, derating or external cooling is required. Construction follows UL/CSA guidelines, allowing installation on North American machinery without additional certification steps. The unit is supplied without a holding brake, so static position retention must be provided by the drive or an external mechanical lock.

Power and feedback conductors terminate inside a terminal box, and all connectors are oriented on the B-side of the housing to simplify gland placement in flame-proof enclosures. Motion is transmitted through a plain shaft that includes a sealed frontal centering hole and uses a DIN 332 'DS' thread for puller or alignment tools. A shaft seal is fitted to protect the bearing cavity from process vapors, and the 144 winding code matches the motor’s electrical constants to standard IndraDrive explosion-proof converters for consistent torque linearity across the operating speed range.
