Internal Product Review
The MKE098B-047-KG1-BENN is a Bosch Rexroth servo motor for potentially explosive areas featuring ATEX compliance and a terminal box connection. Standstill torque of 12.0 Nm and maximum torque of 43.5 Nm give this unit impressive reserve for dynamic axis control. An integrated holding brake rated at 11 Nm is a strong advantage for secure positioning in hazardous-area machinery.

Product Description:
The MKE098B-047-KG1-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it complies with ATEX housing standards for use in zone-rated machinery. The motor uses winding code 047 and has a plain shaft with a frontal centering hole and a DIN 332 DS thread. A terminal box on the B-side handles power and feedback connections, and the integrated holding brake supports static load cases in hazardous environments.
Under steady-state thermal conditions of 60 K, the motor can deliver 12.0 Nm of continuous torque while drawing 9.8 A of continuous standstill current. This operating point corresponds with a phase inductance of 1.20 mH and a phase resistance of 8.400 Ω. Brief overloads are permitted up to a peak torque of 43.5 Nm and an RMS current of 44.3 A, which supports fast indexing moves before the Class 155 F insulation system reaches its allowable temperature. The maximum speed is 4500 rpm, matched to a back-EMF constant of 91.0 V per 1000 rpm for predictable drive matching. The brake supplies 11 Nm of holding torque when de-energized, and a discharge capacitance of 6.7 nF helps suppress shaft voltage in inverter applications.
Dynamic response benefits from a rotor moment of inertia of 0.00430 kg·m², allowing rapid acceleration without compromising positional stability. A torque constant of 1.41 Nm/A supports current-loop tuning, while operation is permitted at ambient temperatures from 0 to +40 °C so external cooling is not required under normal duty. The motor weighs 18.0 kg without the brake, and its construction includes a shaft seal plus a sound pressure level of 61.8 dB(A) ±3 dB for acoustic planning. All conductors terminate in the sealed terminal box, and cables exit on the B-side to maintain clear routing inside explosion-proof housings.
