Product Description:

The MKE037B-144-AG1-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for use in potentially explosive areas, it drives position-controlled axes in filling, mixing, and conveying lines where combustible gases may be present. By combining explosion-proof construction with encoder feedback and a holding brake, the motor supplies regulated torque and speed without introducing ignition sources into the work area. This makes it suitable for automated processes that require accurate motion in classified operating zones.

Enclosure integrity is important in hazardous areas, so the motor carries an ingress rating of IP 65 and a housing compliant with ATEX requirements. Continuous duty is permitted within 0 to +40 °C, and its windings use insulation class 155 (F) to withstand elevated internal temperatures during operation. Axis position is monitored by an optical single-turn Hiperface encoder that generates 128 increments per revolution through the S1 scanning head, giving adequate resolution for indexing tasks while keeping feedback wiring compact. The built-in holding brake secures the rotor when supply power is removed, and winding code 144 matches the electrical characteristics expected by compatible Bosch Rexroth drive controllers.

All power and signal conductors enter through a terminal box mounted on the B-side, which leaves the drive end more accessible for coupling work. Output torque is delivered by a plain shaft equipped with a DIN 332-compliant DS thread and a front centering hole, simplifying attachment to couplings or gear stages. A shaft seal helps block gas or dust migration along the journal, and the smooth ATEX housing surface is easier to clean in classified zones. This shaft arrangement also supports accurate alignment of connected drivetrain components during installation and operation.
