Product Description:
The MKE098B-047-GP1-BENN is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat in the MKE Synchronous Motors series. Designed for drive tasks where ignition sources must be controlled, the unit converts electrical power into regulated mechanical motion for conveyors, mixers, and positioning axes installed in hazardous industrial zones. Its housing meets ATEX requirements, allowing operation in Zone 2 gas environments.
At a 60 K winding temperature rise, the motor delivers a continuous torque of 12.0 Nm while drawing 9.8 A at standstill. When rapid acceleration is required, it can reach a peak load of 43.5 Nm with a corresponding crest current of 44.3 A. The electromagnetic design yields a torque constant of 1.41 Nm/A, so closed-loop controllers can estimate shaft load directly from phase current. The 047 winding has a resistance of 8.400 Ω and an inductance of 1.20 mH at 20 °C, which affects drive sizing and current ripple. A voltage constant of 91.0 V per 1000 rpm and a maximum speed of 4500 rpm support responsive motion, while a rotor inertia of 0.00430 kg·m² helps maintain stable speed changes. Thermal operation is permitted from 0 to +40 °C under insulation class 155 F.
The integrated holding brake supplies 11 Nm of static torque, allowing the shaft to remain in position after power is removed. Terminations are routed through a terminal box mounted on the B-side of the housing, and the enclosure uses a shaft seal to help reduce gas ingress. Internal suppression components present a discharge capacity of 6.7 nF, which helps limit voltage transients on the power leads. Acoustic emissions remain at 61.8 dB[A] ±3 dB, which helps keep sound levels moderate in nearby work areas. The keyed shaft follows DIN 6885 for straightforward coupling to gear stages, and a mass of 18.0 kg supports stable installation.
