Product Description:
The MKE047B-144-AG0-LUNN belongs to the MKE Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for potentially explosive areas where accurate position and speed regulation are required by continuous-duty machinery. When paired with certified drives, this motor delivers closed-loop torque control so that conveyors, mixers, or dosing pumps in hazardous zones can run at commanded set points without introducing ignition sources.
The power and feedback conductors exit on the left side of the frame through a compact terminal box, simplifying cable routing when the motor is mounted in tight enclosures. Rotor feedback is produced by an integrated encoder that delivers 128 discrete counts per revolution, and the sensing element is a single-turn Hiperface optical encoder model S1, giving absolute position within one turn for rapid homing after power-up. Magnetic excitation comes from 4 rotor pole pairs, which influence the electrical relationship between the motor and the selected drive settings. The unit is supplied without a holding brake, which allows the shaft to coast freely when power is removed and reduces overall motor length where installation space is limited.
The motor uses insulation class 155 (F), permitting winding temperatures up to 155 °C during intermittent overloads while retaining dielectric strength. A plain shaft with a frontal centering hole provides concentric alignment for couplings, and a dedicated shaft seal helps prevent vapor or dust ingress at the bearing journal. Threaded engagement follows a DIN 332 'DS' thread, enabling extraction tools to be fitted during maintenance without external adapters. The cast housing conforms to UL and CSA requirements so the motor can be installed in North American classified locations that require certified equipment.
