Product Description:
The MKE118B-024-BG0-KI4 is a flameproof-rated servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It supplies closed-loop rotary motion in hazardous areas where explosive gas mixtures can occur, supporting presses, mixers, and conveyor drives that require precise speed regulation. Because it is delivered without a holding brake, retention during power-off must be provided externally.
At a 60 K housing rise, the motor holds 28.0 Nm of torque while drawing 15.3 A, giving machinery a steady stall margin. Short bursts can reach 102.0 Nm, and the rotor can spin up to 4000 rpm. A rotor inertia of 0.01940 kg·m² helps limit overshoot during rapid reversal. The 024 stator winding has 7.60 Ω resistance and 0.580 mH inductance, which influence the current gradient commanded by the drive. An optical S2 single-turn EnDat 2.1 encoder with 2,048 increments reports shaft angle, and a voltage constant of 130 V per 1000 rpm provides predictable back EMF. The motor is intended for ambient temperatures from 0 °C to +40 °C.
Peak electrical demand is 69.1 A RMS, and each ampere produces 2.12 Nm/A, which makes drive sizing straightforward. The motor’s capacitance of 10.3 nF supports common-mode filtering, and its sound pressure level stays below 61.1 dB[A]. Overall mass is 45.0 kg, providing thermal inertia while remaining manageable for vertical mounting. Connection hardware is located on top of the housing in a sealed terminal box that accepts 13–16 mm cable glands, and a shaft seal helps block dust ingress. Class F insulation tolerates winding temperatures associated with stall conditions. A DIN 332 DS thread and a frontal centering hole simplify coupling to the load. The plain shaft design includes a discharge path and protection measures for explosive atmospheres.
