Product Description:
The MKE118D-012-AG0-KUN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for potentially explosive areas, it provides controlled rotary power to mixers, agitators, or conveyors where ignition-source classification is critical. An optical single-turn Hiperface encoder, model S1 with 128 increments, is integrated for position feedback, and all power and feedback conductors enter through a top-mounted terminal box. The unit is supplied without a holding brake, so static load retention must be provided by the machine or the drive.
Under steady thermal conditions of 60 K, the motor delivers 48.0 Nm of continuous standstill torque while drawing 13.0 A of continuous current. The housing carries an IP65 rating, so dust ingress is prevented and jet water cleaning is permitted in washdown cells. For transient acceleration, the winding can reach a maximum RMS current of 58.5 A and produce up to 187.0 Nm of peak torque. Mechanical speed is limited to 2000 rpm, and the rotor balance and bearing set keep vibration within a 61.1 dB[A] sound level. The discharge capacitance of 20.2 nF influences common-mode currents, and a back-EMF constant of 263.5 V per 1000 rpm helps with inverter voltage selection.
Thermal management is supported by Class F insulation and a permissible ambient range of 0 to 40 °C. Within that temperature window, the frame weighs 65.0 kg and dissipates losses through its UL/CSA-compliant housing. Electromechanical responsiveness is set by a torque constant of 4.29 Nm/A and a winding inductance of 15.000 mH, values that affect current loop bandwidth in the drive controller. The laminated rotor has an inertia of 0.03620 kg·m², which supports smooth speed regulation on long conveyor or mixer shafts. The motor has a plain shaft with a DIN 332 DS thread and a frontal centering hole. It also has a shaft seal, top-mounted connections, winding code 012, and a resistance of 0.98 Ω.
