Product Description:
The MKE118B-024-DG0-KE4 servo motor is produced by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Engineered for potentially explosive environments, the unit meets ATEX housing requirements and provides closed-loop motion for conveyor sections, mixers, or machining axes in automation cells. When paired with a compatible drive controller, it converts commanded current into controlled rotational speed and position so that process equipment can maintain repeatable cycles without introducing ignition sources.
The 024 winding is designed for a thermal rise of 60 K, delivering a continuous standstill torque of 28.0 Nm while drawing 15.3 A of current. A torque constant of 2.12 Nm/A links commanded current to shaft output, and the electrical network includes a winding resistance of 7.60 ohms and an inductance of 0.580 mH; these values influence servo bandwidth and inverter sizing. Peak transients can reach 69.1 A RMS, and the system back electromotive force is 130.0 V per 1000 rpm. Capacitance to ground is limited to 10.3 nF, supporting EMC conformity, while the optical M2 encoder supplies 2,048 absolute increments through EnDat 2.1 for accurate feedback.
Mechanically, the motor can generate up to 102.0 Nm for short-term load surges and can reach speeds up to 4000 rpm when commanded by the drive. The low rotor inertia of 0.01940 kgm² supports rapid acceleration, while the total mass of 45.0 kg helps reduce vibration in fixed installations. Operation is specified for ambient temperatures from 0 °C to 40 °C, and airborne noise remains at 61.1 dB(A) ±3. A plain shaft with a frontal centering hole, a DIN 332 DS thread, and a shaft seal transmits torque while maintaining IP protection. Electrical leads enter a terminal box on top of the housing through 13–16 mm glands, and insulation materials rated to class 155 F permit reliable service without a holding brake in explosive areas.
