Product Description:

The MKE047B-144-KP1-AUNN is a servo motor for potentially explosive areas manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. By combining flame-path construction with an integral feedback interface, the unit supplies controlled torque and speed to drives used in hazardous zones. It is intended for process plants, paint lines, refinery skids, and other areas where combustible gases or vapors may be present. These features also allow the motor to work with standard IndraDrive controllers for closed-loop motion tasks.

Electrical and mounting parameters describe how the motor connects to the drive and machine. Power and feedback lines enter through a terminal box, and those terminations are oriented toward the machine's A-side, so cable trays can be planned without sharp bends. Four stator windings grouped as 144 accommodate thermal loading while keeping copper fill factor consistent with low-voltage servo drives. Rotor topology uses 4 pole pairs, which sets the electrical frequency needed to reach application speed and influences synchronous torque ripple. To endure heat produced by rapid cyclic duty, the insulation system is rated at 155 (F), allowing winding temperatures up to 155 °C before dielectric stress rises.

A permanent-magnet brake is factory-installed, and its static holding capacity is 2.2 Nm, supplying axial load support during vertical stops or power loss. The enclosure follows UL/CSA construction rules for North American acceptance in Class I Division environments. Output torque is delivered through a shaft with keyway, and the key conforms to the DIN 6885 profile for straightforward coupling to pulleys or gearboxes. The motor also has a shaft seal that blocks vapor ingress toward the bearing cavity and helps maintain lubricant life when washdown or solvent mists are present.
