Product Description:
Bosch Rexroth Indramat manufactures the MKE098B-047-BG0-BUNN, a servo motor for potentially explosive areas in the MKE Synchronous Motors series. The unit supplies regulated rotary motion to hazardous-location machinery where precise speed and torque control are required without introducing ignition risks. Its design enables direct coupling to gear stages or load shafts used in conveyors, mixers, and process valves found in chemical plants and refineries.
At standstill, the motor produces a continuous torque of 12.0 Nm while drawing 9.8 A, figures suited to holding and indexing loads at low speed. When acceleration peaks are demanded, it withstands 43.5 Nm and up to 44.3 A RMS. A torque constant of 1.41 Nm/A links the supplied current to generated torque, and winding code 047 uses 1.20 mH inductance and 8.400 Ω resistance for the motor's electrical behavior and copper losses. The stator’s discharge capacity is 6.7 nF. Thermal endurance is supported by Class 155 F insulation, and the housing is UL/CSA compliant. Power and feedback conductors enter from the B-side through a terminal box sealed against dust and oil. A shaft seal is present, but the unit is supplied without a holding brake. The A-weighted sound pressure level is 61.8 dB(A) ±3.
It reaches a top speed of 4500 min⁻¹, and the back EMF rises proportionally with a voltage constant of 91.0 V/min⁻¹, so the selected drive must accommodate that value. Dynamic response benefits from a rotor inertia of 0.00430 kgm², allowing rapid reversal without overshoot, and the motor body weighs 18.0 kg, which adds thermal mass. Position feedback is delivered by an optical single-turn EnDat 2.1 encoder, model S2, that outputs 2,048 increments per revolution. Operation is permitted at ambient temperatures between 0 °C and +40 °C. Mechanical coupling uses a plain shaft with a frontal centering hole and a DIN 332 DS thread for puller hardware.
