Product Description:
The MKE047B-144-AG0-BENN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is intended for motion tasks in potentially explosive atmospheres, supplying closed-loop torque and speed control to machinery located in hazardous zones of industrial plants. This motor is suited for applications that require both precise servo performance and installation in protected process areas. The design omits a holding brake, so mechanical locking of the load must be handled externally when power is removed.
The motor housing meets ATEX requirements, so it can be mounted where explosive gas or dust is present. Heat endurance of the stator windings is rated for an insulation class of 155 (F), allowing the unit to run at elevated internal temperatures without degrading the enamel or slot liners. Four magnetic pole pairs generate the synchronous field, and the value of 4 sets the basic electrical frequency relationship. Power and feedback leads exit on the B-side, which can simplify routing away from the driven machine. All conductors land in a terminal box that seals against contaminants and permits rigid conduit adapters.
Position feedback is delivered by an optical encoder that produces 128 counts per revolution, supporting low-speed velocity regulation and repeatable homing. The feedback device uses the Optical encoder, Singleturn Hiperface format and is identified as model S1, which supports compatibility with Hiperface-capable controllers. This encoder arrangement provides stable rotor position feedback during normal servo operation and supports consistent speed control at low shaft speeds. The rotor uses a plain shaft end machined with a frontal centering hole to simplify coupling alignment, while threaded retention uses a DIN 332-compliant DS thread for standardized puller tools. A shaft seal is present to block vapor ingress, and winding code 144 matches the motor's electrical characteristics to the intended drive inverter.
