Product Description:
The MKE118B-024-PP0-KUN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for hazardous areas, where it provides rotary motion for actuators, mixers, and positioning modules while helping limit ignition risk in the surrounding environment. The housing follows UL and CSA requirements, power is routed through a top terminal box, and the motor uses a keyed shaft with a shaft seal to help keep dust and oil away from internal components. This layout supports installation in equipment that must combine controlled motion with enclosed power connections and secure mechanical coupling.
At standstill, the motor generates a continuous torque of 28.0 Nm while drawing 15.3 A at a 60 K winding rise. During acceleration, the shaft can reach speeds up to 4000 rpm, and the inverter may supply a peak phase current of 69.1 A without exceeding the stated thermal limit. A torque constant of 2.12 Nm/A relates output torque to stator current, which supports predictable current-controlled operation. The 024 winding has a resistance of 7.60 Ω, insulation class F, and a voltage constant of 130 V per 1000 rpm, so the drive must provide enough output voltage as speed increases.
Mechanical behavior is influenced by a rotor moment of inertia of 0.01940 kg·m², which helps the motor maintain stable rotation under changing load conditions. The motor has an installation weight of 45.0 kg, so the mounting structure must support both the static mass and the forces created during operation. Rated performance is maintained from 0 °C to +40 °C ambient, and operational noise is rated at 61.1 dB[A] ±3 for use in machine rooms with controlled sound levels. An inductance of 0.580 mH limits current rise during command changes, while the 10.3 nF discharge capacity helps reduce high-frequency voltage spikes. The DIN 6885 keyed shaft and shaft seal provide torque transfer with protection against lubricant migration. Because the motor is supplied without a holding brake, any position retention during standstill must come from external clamping or drive-generated torque.
