Product Description:

The MKE047B-144-KP0-BENN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor for potentially explosive areas, engineered to drive position-controlled axes inside hazardous-location machinery where ignition risks must be minimized. By combining a flameproof housing with ATEX conformity, the motor allows closed-loop motion control in chemical processing lines, paint booths, and similar environments without relocating the drive outside the classified zone. The motor is intended for motion systems that still require accurate speed and position control in areas where standard industrial motors may not be suitable.

Power and feedback leads exit on the B-side, and the wiring lands in a terminal box for cable connections. This arrangement keeps electrical terminations enclosed and organized when the motor is installed in process equipment. For braking, the unit is supplied without a holding brake, so static load retention must be handled by the drive or an external latch. The housing meets ATEX requirements for explosive dust and gas atmospheres, and the windings use insulation rated at 155 (F) to tolerate elevated internal temperatures under continuous torque demand. Winding code 144 indicates the coil impedance and current ratings used with matching MKE drives.

Rotor design uses 4 pole pairs, which influences torque ripple characteristics and commutation response. Mechanical power is delivered through a shaft with keyway, which supports positive torque transmission to standard couplings and driven components. The key slot follows the DIN 6885 keyway profile for standardized mating hardware. A dedicated shaft seal helps prevent lubricant migration and blocks airborne contaminants from entering the bearing chamber. The sealed shaft area also helps limit dust entry in pressurized or dirty enclosures.
