Product Description:

The MKE047B-144-GP1-BENN is a servo motor produced by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Built for potentially explosive areas, it converts commanded current into controlled torque and speed for machine axes where flammable gases or dust may be present. Its compact frame supports continuous duty in process valves, conveyors, and filling equipment installed in hazardous industrial zones. Because motion remains servo controlled, the motor can handle repeated starts, stops, and low-speed positioning tasks with consistent response.

The power and feedback conductors are routed on the B-side, which helps keep cable runs away from the drive end of the motor. An integrated terminal box provides screw-clamp terminations compatible with armored cables used in classified locations. A permanent-magnet brake delivers 2.2 Nm of static torque so the shaft remains locked when mains power is off. That brake arrangement is useful when the axis must stay in place during shutdowns or power loss. The die-cast housing meets ATEX requirements for installation in zone-rated environments without a secondary enclosure. Stator windings use 155 (F) insulation, allowing high internal temperature tolerance during extended operation.

The electromagnetic design uses 4 pole pairs, which supports synchronous rotation and smooth low-speed operation. Mechanical power is transmitted through a keyed shaft with a DIN 6885 keyway profile, allowing standard couplings to pulleys or gearboxes. A shaft seal helps block oil vapor and dust from reaching the bearing cavity and supports reliable operation in contaminated process areas. The stator uses winding code 144, which corresponds to the electrical characteristics expected by a matching inverter for stable closed-loop control. This combination of keyed output and sealed bearing protection suits equipment that operates near powders, vapors, and other airborne contaminants.
