Product Description:

The MKE037B-144-GP1-BUNN belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat. Classified as a servo motor for potentially explosive areas, it is used to position and regulate mechanical loads inside hazardous industrial zones where flammable gases or dust may be present. The motor couples with certified drives to deliver closed-loop torque and speed control, allowing conveyors, mixers, or dosing pumps to run at commanded profiles without creating ignition sources. It is suited for applications that require precise motion together with protection for operation in hazardous environments.

This model is protected by an IP65 enclosure, so dust ingress is prevented and water projected from any direction will not interfere with operation. Continuous operation is specified within an ambient range of 0 to +40 °C; staying inside this range avoids thermal derating. Windings are insulated to class 155 (F), meaning the copper can reach 155 °C before insulation aging accelerates. Mechanical power leaves the motor through a shaft with a keyway, and the key follows the DIN 6885 profile for standardized coupling to gearboxes or pulleys. Electrical terminations are routed into a terminal box on the housing, simplifying lead inspection and allowing armored conduit when required. A shaft seal is installed to block oil or process moisture from entering the bearing chamber.

For dynamic stops or vertical axes, the motor integrates a holding brake that clamps the rotor when power is removed. Power and feedback conductors exit on the B-side, keeping cables clear of the load face in tight machine frames. This cable exit arrangement helps keep wiring away from the driven load in compact installations. Conformance with UL/CSA standards supports use in North American hazardous-location panels. The stator is wound to code 144, a winding that matches the series drive modules for rated voltage and current.
