Product Description:

The MKE047B-144-GG0-BENN is a brushless servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. This unit is intended for use in potentially explosive atmospheres and drives position-controlled axes in chemical processing, painting, or grain-handling cells where ignition sources must be minimized. When paired with a compatible digital drive, the motor provides closed-loop torque and speed regulation for precise axis motion. Its enclosed design supports use in regulated areas where flammable vapors or combustible dust may be present during normal machine operation. That makes it suitable for motion tasks that require both repeatability and controlled acceleration.

Power and encoder leads exit on the B-side, so routing can follow the rear of linear stages without conflicting with coolant lines or nearby machine members. Terminations are made inside a terminal box, allowing armored conduit to be landed directly on the housing for protected cable entry. The rotor is supplied without a holding brake, so stopping torque must be provided by the drive or an external mechanical lock when the axis is at rest. Compliance with ATEX requirements makes the enclosure suitable for Category 2 areas. The windings use insulation class 155 (F) to withstand the heat rise associated with repeated cyclic duty. This arrangement keeps electrical connections protected while supporting orderly separation of motor power and feedback wiring. It also helps keep cabling enclosed at the motor rather than exposing separate connectors.

The electromagnetic package uses 4 pole pairs to support smooth rotation and strong torque output in a compact housing. Torque is produced through a stator with a 144 winding, a code matched to the electrical characteristics expected by standard IndraDrive power modules. The pole and winding combination supports stable commutation across the motor's operating range. Mechanical output is transmitted through a plain shaft fitted with a DIN 332 'DS' thread and a frontal centering hole, which helps with coupling alignment and shaft-end retention. This shaft-end arrangement supports secure attachment of mating components without adding a keyed profile. A molded shaft seal blocks oil or dust intrusion and helps preserve the motor's enclosure integrity when it is installed in sealed pump housings or agitator heads.
