Product Description:

The MKE037B-144-GG1-BUNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in hazardous areas where controlled motion is required together with measures that reduce ignition risk. By converting regulated electrical power into torque and speed, the motor supports accurate positioning of actuators, gearboxes, and other driven machine elements. Its design suits automated equipment that must maintain repeatable motion while operating under strict safety requirements.

Its enclosure has an ingress protection rating of IP 65, which helps keep dust out and protects the motor against water projected from a nozzle. The winding uses Insulation Class 155 (F), allowing the insulation system to withstand elevated internal temperatures during operation. The permitted ambient temperature range is 0 to +40 °C, which supports use in typical indoor industrial environments without special cooling measures. For power-off holding, the motor is equipped with a holding brake that secures the shaft when supply current is removed. A shaft seal is installed at the output end to help prevent contaminant entry and support reliable operation in enclosed machine assemblies.

Electrical connections are made inside a terminal box mounted on the housing’s B-side, which keeps the cable entry away from the driven load and can simplify routing in compact installations. The aluminum housing complies with UL/CSA requirements for listed industrial equipment, supporting use in North American applications. A plain shaft with a front centering hole connects to common coupling arrangements, and the output includes a DIN 332 “DS” thread for extractor tools during service. Winding code 144 is used for this motor version, and the shaft arrangement supports accurate torque transfer during repeated starts, stops, and direction changes.
