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.
