Product Description:
The MKE098B-047-BG0-BENN is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it converts drive commands from certified controllers into rotational motion where flammable gases or dust may be present. Its frame follows the manufacturer’s explosion-proof housing standard, and the motor is intended for precise positioning and speed regulation on pumps, mixers, or conveyor axes installed in hazardous zones. This type of housing is used where a standard industrial motor enclosure is not suitable.
The motor delivers a continuous standstill torque of 12.0 Nm while drawing 9.8 A. The winding 047 design is paired with a resistance of 8.400 Ω and an inductance of 1.20 mH. Peak demand is supported by a maximum current of 44.3 A, and the rotor can reach 4500 rpm for high-speed duty. Operation is permitted from 0 to +40 °C, and the enclosure meets ATEX requirements for surface temperature control. Electrical connections are routed on the B-side through a terminal box, which also contains the 6.7 nF discharge capacitor. Feedback is supplied by an optical single-turn EnDat 2.1 encoder of type S2 with 2,048 increments, giving absolute position information to the drive. The stator insulation is Class 155 F, and the unit is supplied without a holding brake. A plain shaft with a DIN 332 DS thread, a front centering hole, a shaft seal, and a B-side cable exit completes the mechanical interface.
The motor has a torque constant of 1.41 Nm/A, which supports predictable acceleration when combined with a rotor inertia of 0.00430 kgm². Up to 43.5 Nm of peak torque is available for short bursts, and the voltage constant is 91.0 V per 1000 rpm. Total mass is 18.0 kg, allowing rigid mounting without auxiliary supports, and airborne noise remains at 61.8 dB[A] ±3 dB during continuous service.
