Product Description:

The MKE098B-047-PG0-BENN is a servo motor engineered by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified for operation in potentially explosive atmospheres, the unit follows ATEX housing requirements while delivering rotational power to drive automation axes in hazardous processing lines. The motor’s plain shaft, combined with integrated grounding paths, allows direct coupling to gear stages or pump impellers without added interface parts. It is suited for hazardous-area machinery that still requires accurate rotary motion.

With a 60 K winding temperature rise, the motor sustains a continuous output of 12.0 Nm with a corresponding phase current of 9.8 A. The torque-producing capability per ampere is set by a constant of 1.41 Nm/A, and the stator uses winding code 047 with a resistance of 8.400 Ω and an inductance of 1.20 mH. A voltage constant of 91.0 V per 1000 rpm allows speed control up to 4500 rpm on standard 400 V inverters. The electrical design includes a discharge capacitance of 6.7 nF to limit common-mode transients, class 155 F insulation, and a terminal box connection on side B for EMC-compliant cabling. Operation is permitted between 0 °C and +40 °C, and the motor comes without a holding brake to avoid frictional drag in continuous-duty drives.

For acceleration peaks, the stator can deliver 43.5 Nm, while momentary demand can reach 44.3 A rms without thermal overload. The rotor inertia of 0.00430 kg·m² supports fast reversals, and the overall mass of 18.0 kg helps keep mounting loads manageable. A frontal centering hole and a DIN 332 DS thread at the shaft end simplify puller use during coupling removal. An integral shaft seal blocks process vapors from entering the bearing space, and the motor’s sound pressure level of 61.8 dB(A) ±3 keeps noise output within common plant limits.
