Product Description:

The MKE047B-144-KG0-BENN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for potentially explosive areas, the unit supplies rotary motion to drive machinery in process lines and material handling cells where ignition sources must be minimized. Its flameproof enclosure meets Category 2 requirements for Zone 1 installations handling Group IIC gases and conductive dust. This arrangement allows the motor to be used where enclosed operation and controlled surface temperatures are important for safe machine motion.

Electrical and feedback conductors exit on the B-side, and the device uses a terminal box rather than molded connectors, which supports sealed cable routing in enclosed installations. The motor is supplied without a holding brake. Compliance with the ATEX housing standard shows that the enclosure is suited to hazardous dust or gas areas. Thermal durability is supported by insulation rated at 155 (F), which allows the windings to operate at elevated temperatures without reducing insulation performance during normal service. These features support reliable motion control in applications where enclosure integrity and controlled heat are both important.

Motion is delivered through a plain shaft that includes a frontal centering hole for accurate coupling alignment during installation. A positive lip seal is fitted at the shaft interface to retain lubrication and help block particle ingress during operation. The free end also includes a DIN 332 'DS' thread, which allows extraction screws to separate the motor from the driven element when removal is required. The stator uses winding 144, which sets the electrical values used within the MKE047 frame size. Together with the sealed shaft area and terminal-box connection layout, this winding arrangement supports stable torque production in enclosed industrial environments.
