Product Description:

The MKE118B-024-DG1-KE4 is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for motion axes in potentially explosive industrial zones, where accurate speed control and closed-loop positioning are required. When paired with a compatible drive controller, the motor converts electrical power into controlled rotary torque for conveyors, mixers, and filling equipment used in demanding process lines.

Winding design 024 indicates the electrical characteristics used by this motor. At a 60 K stator temperature rise, it sustains 28.0 Nm of torque while drawing 15.3 A. At the same thermal point, the motor has a torque constant of 2.12 Nm/A, a phase resistance of 7.60 Ω, and an inductance of 0.580 mH. For short dynamic events, it can reach 69.1 A and 102.0 Nm up to 4000 rpm. The 0.01940 kg·m² rotor supports quick acceleration, and the 10.3 nF discharge capacitance helps route shaft currents to ground. Position feedback is supplied by an optical multiturn EnDat 2.1 encoder, model M2, with 2,048 increments per revolution, and acoustic emission is 61.1 dB(A).

The mechanical design is intended for hazardous locations and complies with ATEX requirements. It uses a sealed housing, a plain shaft with a frontal centering hole, and a DIN 332 DS thread for positive drive coupling. A shaft seal is fitted, and the holding system uses a permanent-magnet brake that provides 32 Nm when power is removed. Power and feedback conductors enter through the top of the terminal box by means of 13 to 16 mm cable glands, which can simplify cable routing. Thermal limits permit continuous duty within 0 to +40 °C, and the insulation class is 155 (F). With a mass of 45.0 kg, the motor offers stable mounting and solid mechanical support during operation.
