Product Description:

Bosch Rexroth Indramat’s MKE118D-027-NG3-KUN is a servo motor in the MKE Synchronous Motors series. The unit is built for positioning and speed control in automated systems that may be located in potentially explosive zones, providing the mechanical output needed to drive conveyors, gantries, or mixers. It integrates a factory-mounted holding brake and a sealed housing so that motion control tasks can be performed safely when flammable gases or dust are present.

At a 60 K winding temperature rise the motor supplies 22.1 A of continuous current and delivers 48.0 Nm of continuous standstill torque. A torque constant of 2.52 Nm/A links current to shaft force, while the 027 winding shows an inductivity of 5.70 mH and a resistance of 0.350 Ohm at 20 °C. Rotor inertia is 0.03620 kg·m², and the discharge capacity is 20.2 nF. Conductors reach a terminal box mounted on the top of the housing. The plain shaft carries a frontal centering hole, a DIN 332 “DS” thread, and a shaft seal retained by the 70 Nm holding brake. Additional data include UL/CSA housing approval, F-class insulation, a sound pressure level of 61.1 dB[A], a weight of 65 kg, and an ambient range of 0 °C to 40 °C.

When peak demand occurs, the winding can accept a maximum sinusoidal current of 99.6 A and generate up to 187.0 Nm of torque for short durations. The mechanical output can be sustained up to 3000 min⁻¹, a speed matched to the 154.5 V/1000 rpm voltage constant. The enclosure carries an ingress protection rating of IP 65, blocking dust and water jets typical of wash-down production cells. These limits, along with the UL/CSA housing approval, establish the application window for aggressive acceleration while maintaining thermal stability. The combination of high current capacity, speed rating, and sealed construction allows the motor to answer short-cycle demands in material handling or mixing systems without compromising enclosure integrity.
