Product Description:

The MKE047B-144-AG0-AUNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for hazardous areas where flammable gases or dust may be present and precise rotary motion is still required. The motor can couple directly to gear stages or machine shafts for controlled motion on processing and handling equipment. Its electrical interface is intended for drives that monitor temperature and position through the integrated optical feedback system. This supports controlled movement in installations that must combine accurate servo performance with operation in regulated environments.

Connection hardware is oriented toward the A-side, and all power and signal leads enter through a rugged terminal box that supports protected cable routing. Rotor position is measured by an optical encoder that delivers 128 increments per revolution. The encoder uses the Single-turn Hiperface protocol, so absolute position is available as soon as the drive is energized. This feedback arrangement helps the connected drive correct speed and position errors during dynamic motion. The winding uses insulation class 155 (F), which allows elevated internal temperatures while protecting the insulation system during normal operation.

Torque is produced by 4 pole pairs on the rotor, and the electromagnetic layout uses the 144 winding to match compatible Indramat power modules. The cast housing meets UL/CSA guidelines for North American hazardous locations. A plain shaft with a frontal centering hole is fitted with a radial shaft seal to help keep dust and fluid away from the internal bearings. The centering hole also supports accurate alignment during coupling installation. Threaded engagement uses the DS thread, which supports precise axial pull-up. The motor is supplied without a holding brake, so any load that must remain stationary during power loss requires external holding or stopping equipment.
