Product Description:

The MKE037B-144-GP0-AUNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for use in potentially explosive areas, the unit delivers controlled torque and speed to conveyors, mixers, and positioning axes located in hazardous zones where flammable gases or dust may be present. By pairing its flameproof construction with compatible drive controllers, the motor allows process equipment to maintain precise motion profiles while meeting ignition-protection requirements in chemical, pharmaceutical, and paint-finishing plants.

The motor operates reliably in ambient conditions from 0 to +40 °C, so no additional cooling measures are required for most indoor installations. Its die-cast housing carries an ingress protection rating of IP65, which blocks dust and water jets that could otherwise compromise winding insulation. Thermal endurance is supported by Class 155 (F) insulation, which permits internal copper temperatures up to 155 °C during continuous duty. The 144 winding code identifies the electrical characteristics used by the matching drive for current control. Field wiring is completed inside a sealed terminal box, which provides a straightforward screw-clamp interface and allows armored conduit to connect directly to the enclosure.

All power and feedback leads emerge on the A-side, which can simplify cabinet layouts that require service access from one direction. The housing meets UL/CSA construction rules for installation in Class I or Class II hazardous locations in North America. It is supplied without a holding brake, so position must be secured by external mechanical locks or continuous servo torque when the axis is stopped. The output shaft uses a keyway made to the DIN 6885 profile, ensuring positive torque transfer to pulleys or gearboxes, and a dedicated shaft seal helps prevent lubricant migration or particle ingress along the journal.
