Product Description:

The MKE047B-144-AP0-BUNN servo motor is produced by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is identified as a servo motor for potentially explosive areas, so it can be installed in hazardous industrial zones where flammable gases or dust may be present. Within an automated installation, the motor converts drive controller commands into rotational motion for actuators, conveyors, or pump shafts, providing the precise speed and torque regulation required by process equipment in chemical plants, paint systems, and similar environments.

The electrical interfaces are routed through a terminal box, and the B-side connection orientation can keep power and feedback cables away from moving machine parts. Position feedback is generated by a single-turn Hiperface optical encoder that delivers 128 increments per mechanical revolution, giving the control loop adequate resolution for short-stroke indexing. The motor uses 4 magnetic poles, which correspond to two pole pairs and influence the electrical frequency demanded from the inverter as well as torque ripple. Compliance with the DIN 6885 keyway standard allows straightforward coupling to gearboxes, and the S1 encoder model supports reliable digital communication in high-EMI surroundings.

The motor is supplied without a holding brake, so external measures are required when static holding torque is needed after power is removed. The winding insulation is rated to class 155 (F), permitting continuous operation while the frame temperature remains within the thermal limits of that class. A certified enclosure meeting UL/CSA requirements supports use in North American installations. A positive shaft seal protects the internal bearing chamber against oil spray or fine dust when the unit is mounted in a washdown or paint booth environment.
