MKE118B-024-PP0-KE4
MKE Synchronous Motors
The MKE118B-024-PP0-KE4 synchronous servo motor is manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it supplies controlled rotary motion to hazardous-zone equipment such as mixers, conveyors, and printing tables where ATEX compliance is mandatory.
At 60 K winding temperature rise the motor delivers a continuous torque of 28.0 Nm while drawing 15.3 A; these figures set the baseline for sizing the drive amplifier during stall or low-speed duty. During acceleration the unit can reach 102.0 Nm and accept 69.1 A RMS, enabling rapid load changes. Output speed tops out at 4000 min⁻¹, a limit tied to the 155 (F) insulation system and the 0…+40 °C ambient range. Electrical behavior depends on winding code 024, a 0.580 mH phase inductivity and 7.60 Ω phase resistance, which shape current ripple and controller bandwidth. Connection is through a top-mounted terminal box that fits 13.0 to 16.0 mm cable glands. The device is supplied without a holding brake, so static torque must be handled externally.
A rotor moment of inertia of 0.01940 kg·m² balances quick response with stable load control, and the assembly weight of 45.0 kg aids vibration damping when the motor is frame-mounted. Force is converted efficiently thanks to a torque constant of 2.12 Nm/A and a back-EMF constant of 130.0 V/min⁻¹, parameters that help drive controllers predict voltage demands during transients. The shaft follows DIN 6885 with a keyed profile and includes a shaft seal, preventing lubricant escape into classified atmospheres. Discharge capacity is limited to 10.3 nF to reduce capacitive ground leakage, and the sound pressure level remains 61.1 dB[A]. Compliance with the specified ambient range is maintained by natural convection, and the winding temperature limit is safeguarded by insulation class F.
