Product Description:

The MKE047B-144-GG1-AUNN is a servo motor engineered by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is classified as a servo motor for potentially explosive areas and is intended for motion axes that must meet ATEX-related safety requirements in industrial automation. By providing closed-loop speed and torque control, the unit serves drives in filling systems, agitators, and conveyor zones situated in hazardous atmospheres where precise positioning and controlled acceleration are necessary. This operating role makes it suitable for process equipment that must maintain repeatable motion while working in areas where ordinary motor designs may not be appropriate.

Power and installation features support use in regulated machine environments. Power and feedback conductors exit on the A-side of the housing, and all terminations are collected in a terminal box, allowing threaded conduit fittings for certified cable entries. A spring-applied holding brake provides 2.2 Nm of static torque to secure vertical or suspended loads when the drive is disabled. The cast enclosure meets UL/CSA construction rules for machinery exported to North America, and its windings use 155 (F) insulation so the permitted temperature rise remains within Class F limits. This arrangement helps the motor fit installations that require controlled cable routing, secure stopping behavior, and recognized construction practices.

Dynamic performance is shaped by the electromagnetic core and shaft arrangement. The rotor carries 4 pole pairs, giving an electrical frequency suited to medium-speed servo tasks while maintaining torque density. Mechanical power is delivered through a plain shaft that includes a frontal centering hole for coupling alignment, and threads cut to the DIN 332 “DS” thread pattern support extraction screws during removal. Internal copper distributed in winding 144 matches the drive voltage class and sets the motor's resistance and inductance profile. The shaft-end layout also supports accurate coupling fit-up and straightforward disassembly when the motor must be separated from the driven load.
