Product Description:
The MKE098B-058-GP0-BENN is a servo motor from the MKE Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a servo motor for potentially explosive areas, it drives position-controlled axes inside hazardous zones where flammable gases or dust may be present. Its housing complies with applicable rules for classified locations while still providing the precise closed-loop torque response required in industrial automation machinery such as filling lines, mixers, or valve actuators.
At a 60 K winding temperature rise, the motor delivers a continuous standstill current of 12.4 A, which produces 12.0 Nm of continuous stall torque for static loads. Short bursts can reach a peak torque of 43.5 Nm during acceleration. Operation is permitted within an ambient range of 0 to +40 °C, and the enclosure meets ATEX requirements. Power and feedback leads exit on the B-side through a terminal box, and the shaft has a DIN 6885 keyway so couplings can be fitted without additional machining. Winding code 058 pairs a 0.740 mH inductance with a 5.80 Ω resistance, while Class F insulation rated for 155 °C and a discharge capacity of 6.7 nF support thermal and electrical performance.
The drive controller may command up to 55.9 A RMS, and at that current the rotor can accelerate quickly because the moment of inertia is 0.00430 kg·m². Rated speed reaches 5000 rpm, which suits gearbox or direct-drive applications that require a wide speed range. A torque constant of 1.09 Nm/A supports current-based torque calculations, and the back-EMF constant is 70.0 V/1000 rpm for field-oriented control. The motor has a shaft seal to limit ingress, and it is supplied without a holding brake, so external locking must be used for power-off safety. Acoustic emission is 61.8 dB(A) ±3, and the assembly weight without the brake is 18.0 kg.
