Product Description:
The MKE118B-024-NP0-KUN is a servo motor for potentially explosive areas manufactured by Bosch Rexroth Indramat in the MKE Synchronous Motors series. Designed for precise position and speed control, it drives actuators, mixers, or conveyor stages that operate in hazardous industrial zones with flammable gas or dust. The motor pairs with certified drives through a flameproof housing that meets UL and CSA requirements, allowing safe torque delivery while complying with North American explosion protection rules.
At ambient temperatures from 0 to +40 °C, the stator windings remain within thermal class 155 (F). During static positioning, the motor can accept 15.3 A continuously and produce 28.0 Nm without exceeding the 60 K temperature rise limit. Fast indexing sequences are supported because the drive may supply 69.1 A RMS for brief periods, allowing the shaft to reach 102.0 Nm of peak torque. Mechanical speed capability reaches 4000 rpm, so reducers can be sized for moderate gear ratios. Winding code 024 has a resistance of 7.60 Ω and an inductance of 0.580 mH, and it works with a voltage constant of 130.0 V per 1000 rpm. Power and feedback conductors enter through a terminal box mounted on the top of the enclosure, which simplifies vertical cabinet layouts.
The dynamic profile is influenced by a rotor inertia of 0.01940 kg·m², which balances acceleration with load stability, and the torque constant of 2.12 Nm/A gives predictable current demand. Total mass is 45.0 kg, which helps absorb heat and reduce vibration during operation, while a factory-installed shaft seal protects the DIN 6885 keyway area from ingress. Airborne noise is limited to 61.1 dB[A], and a discharge capacitance of 10.3 nF helps protect the controller from high-frequency disturbances. Because the unit is supplied without a holding brake, external means of static load retention are required.
