Product Description:

The MKE037B-144-EP0-BE0N is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is intended for motion tasks in potentially explosive industrial zones where precise position and speed control are required. When paired with a compatible drive, the unit converts commanded current into proportional torque, allowing conveyor sections, filling machinery, or packaging axes to move at programmed profiles inside hazardous environments with repeatable motion control.

Ambient operation is rated from 0 to +40 °C, which is the thermal window in which the motor can dissipate internal losses without derating during normal use. Power and feedback wiring exit on the B-side, so cable routing can remain clear on the opposite face. A sealed terminal box provides the electrical interface for power and feedback connections while shielding conductors from dust or moisture. The enclosure carries an ingress rating of IP65, which protects internal parts against dust and low-pressure water jets. Compliance with the European ATEX directive confirms that surface temperatures and sparking behavior are limited so the motor may be installed in Zone 2 gas or Zone 22 dust areas under the stated classifications.

The output shaft is machined as a shaft with keyway to engage couplings or pulleys that use the supplied DIN 6885 profile for positive torque transmission. A dedicated shaft seal blocks lubricant migration from connected gearboxes and helps keep contaminants out of the bearing chamber. Thermal endurance is supported by class 155 (F) insulation, which permits winding temperatures up to 155 °C during intermittent overloads. Because the motor is delivered without a holding brake, static load retention must be handled by the drive or by external locking devices when the motor is de-energized. Winding code 144 matches drive modules with the proper voltage constant for this frame size.
