Product Description:
The MKE118D-012-BG0-KE6 is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is engineered for drive tasks in hazardous zones, where it supplies controlled rotation to actuators and machinery that must meet ignition-protection requirements in industrial automation. The unit is intended for applications that need accurate motion control while also operating in areas with explosion-protection requirements. Its design suits installations where a standard industrial servo motor would not be appropriate for the site conditions.
The motor delivers a continuous standstill torque of 48.0 Nm while drawing 13.0 A at a 60 K winding temperature rise. For dynamic peaks, it can reach a maximum torque of 187.0 Nm and tolerate up to 58.5 A of RMS phase current, allowing short acceleration bursts to a top speed of 2000 rpm. The winding uses code 012 and has a torque constant of 4.29 Nm/A, a voltage constant of 263.5 V per 1000 rpm, a winding resistance of 0.98 Ω, and an inductance of 15 mH. Rotor inertia is 0.03620 kg·m², and the discharge capacitance is 20.2 nF. Position feedback is provided by an optical single-turn EnDat 2.1 encoder, model S2, with 2,048 increments per revolution for precise commutation, and the motor is supplied without a holding brake.
The housing meets the IP 65 ingress rating and is certified for ATEX service in explosive atmospheres, with reliable operation at ambient temperatures from 0 to +40 °C. A plain shaft with a frontal centering hole, a DIN 332 DS thread, and a shaft seal supports direct coupling to the driven machine. Sound pressure during nominal duty is 61.1 dB(A) ±3, and power and feedback conductors enter through a terminal box on top of the frame. The cable gland accepts diameters from 17.0 mm to 19.5 mm. The motor uses Class 155 F insulation and has a total mass of 65.0 kg.
