Product Description:

The MKE047B-144-AP0-AUNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it supplies regulated torque and speed to material-handling stations, mixers, or filling valves that must not create ignition sources. The motor links directly to certified drive controllers, giving position feedback suitable for Zone 1 and Zone 2 installations while maintaining the response times demanded in automated packaging, painting, and chemical processing equipment.

Cable exits are oriented through the connection on side A, an arrangement that simplifies routing when the motor is mounted in vertical frames. Rotor geometry with 4 pole pairs establishes the electrical angle for each mechanical revolution, supporting fine torque modulation at low speeds. Position data come from a single-turn Hiperface optical encoder, and its internal code wheel delivers 128 increments per revolution. Thermal endurance is provided by Class 155 F insulation, which allows winding temperatures up to 155 °C before derating is needed. The motor is supplied without a holding brake, so machinery must rely on external clamps or drive torque to keep loads stationary during power loss.

Power and feedback conductors terminate inside a terminal box that can be turned to suit cabinet layouts. Phase conductors energize the stator’s winding 144, a coil set used for the 047 frame. Output torque is delivered through a shaft with a DIN 6885 keyway, ensuring positive mechanical engagement with couplings, while a dedicated shaft seal blocks fluid ingress along the journal. The aluminum housing meets UL and CSA rules for hazardous-location motors, and the construction complies with North American flameproof requirements without additional enclosures.
