Product Description:

The MKE118B-024-PP0-KE4 is a servo motor for potentially explosive areas built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It uses an ATEX-compliant housing for closed-loop motion axes where precise torque and speed control must be maintained without creating ignition sources. A terminal box on top of the frame accepts power and feedback wiring through 13.0 mm to 16.0 mm cable glands, which supports installation in purged or pressurized enclosures.

The motor delivers a continuous standstill torque of 28.0 Nm while drawing 15.3 A from the drive when the winding temperature rises 60 K above ambient. For acceleration peaks, torque increases to 102.0 Nm and speed can reach 4000 rpm. These limits are supported by a torque constant of 2.12 Nm/A, an insulation system rated to Class 155 (F), and winding code 024, which corresponds to an inductance of 0.580 mH and a resistance of 7.60 Ω that influence current response. The motor does not include a holding brake, so position retention must be provided by the drive or by external mechanics. A shaft seal is installed to help restrict dust ingress, the keyed shaft follows DIN 6885, and acoustic emission is 61.1 ±3 dB[A] during nominal operation.

For brief overloads, the drive may supply up to 69.1 A RMS, and the rotor inertia of 0.01940 kg·m² helps the axis accelerate without excessive drive stress. Operation is permitted from 0 to +40 °C, and within this range the 10.3 nF discharge capacity supports electromagnetic compatibility while the ATEX housing maintains the required surface limits. Top-mounted connections simplify routing in vertical cabinets, and the terminal box helps protect screw joints against vibration. The overall mass is 45.0 kg, which adds thermal inertia that supports continuous-duty operation while remaining suitable for standard lifting equipment.
