Product Description:

The MKE118D-027-PG3-KE4 is a servo motor built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified for use in potentially explosive areas, it supplies closed-loop rotational power to conveyors, mixers, and other zone-rated machinery where ignition sources must be tightly controlled. Integration is through a terminal box on the top of the housing, allowing drive cables to be connected while the enclosure remains sealed. In automated systems, this motor converts electrical energy from a drive into controlled torque and speed for coordinated axis motion.

At a 60 K winding temperature rise, the motor can deliver a continuous shaft torque of 48.0 Nm while drawing a continuous standstill current of 22.1 A. The electromagnetic conversion is characterized by a torque constant of 2.52 Nm/A, and the 027 winding has a resistance of 0.350 Ω and an inductance of 5.70 mH. The housing is rated IP 65, which helps block dust ingress and low-pressure water jets, and a shaft seal supports this protection around the plain shaft with a frontal centering hole. The motor has a weight of 65.0 kg, and the permissible ambient temperature range is 0 to +40 °C with a sound pressure level of 61.1 dB(A).

For dynamic moves, the drive may command up to 187.0 Nm of short-term torque, and speeds can reach 3000 rpm for rapid acceleration of large inertial loads. The electromagnetic circuit supports a peak phase current of 99.6 A without exceeding insulation class 155 F limits. A factory-installed holding brake supplies 70 Nm to secure vertical axes during power loss, and brake release is coordinated through the drive controller. The housing is ATEX compliant for hazardous locations. The shaft uses DIN 332 DS threads, the discharge capacity is 20.2 nF, and the cable entry diameter is 13–16 mm.
