Product Description:
The MKE098B-058-BG0-BENN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for position and speed control tasks in hazardous industrial zones where combustible gases or dust may be present. The motor’s flameproof housing allows it to drive conveyors, mixers, or dosing units located inside classified areas while remaining compatible with standard drive controllers.
At standstill, the motor can supply 12.0 Nm of continuous torque while drawing a thermally rated current of 12.4 A. When dynamic peaks occur, the inverter may command up to 55.9 A, enabling a momentary shaft output of 43.5 Nm without overheating the F-class windings. The stator coils have a resistance of 5.80 Ω at 20 °C and an inductance of 0.740 mH, which influences current ripple and drive bandwidth. A torque constant of 1.09 Nm/A links commanded current to actuator torque and supports closed-loop tuning. Mechanical speed reaches 5000 rpm, so the unit can serve both indexing axes and high-speed spindles. Feedback is provided by an optical single-turn EnDat 2.1 encoder with 2,048 increments, giving the controller absolute rotor position within each revolution. The motor is built without a holding brake, so external devices must secure vertical loads during power loss.
Total mass is 18.0 kg, contributing thermal capacity that delays temperature rise during intermittent overloads. The motor operates from 0 to +40 °C, which aligns with typical control cabinet conditions. A rotor inertia of 0.00430 kg·m² balances quick acceleration with manageable drive currents, making it suitable for medium-load gantry or packaging duties. Compliance with ATEX construction rules supports use in hazardous areas, and a plain shaft with a DIN 332 DS thread and frontal centering hole eases coupling to gearboxes or timing pulleys.
