Product Description:

The MKE116D-027-PP3-KN is a servo motor engineered by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, the unit provides closed-loop speed and position control for filling, mixing, and conveying equipment that must comply with ignition-protection rules. By combining an explosion-proof enclosure with synchronous drive technology, it can be installed directly on Zone-classified machinery. In closed-loop service, the motor responds to drive commands with synchronized torque production, which is useful on axes that must start, stop, and hold position with repeatable accuracy. Its housing uses standard mounting dimensions for this motor platform, which supports integration into compact machine layouts.

Field wiring enters the housing from the top, reducing the need for tight bends in vertical cable runs. Conductors terminate in a sealed terminal box that separates power, feedback, and grounding paths to maintain Ex e clearances. The arrangement keeps connection points enclosed while allowing separate routing for supply and signal conductors inside the housing. Motion is held when power is removed by a spring-applied holding brake for static load retention. The output uses a shaft with a keyway, and the groove follows the DIN 6885 keyway profile. This creates a keyed interface for pulleys or couplings and avoids additional machining at the shaft connection.

The electromagnetic circuit uses winding code 027, which indicates the electrical characteristics expected by MKE-compatible inverters. Matching inverter data to the winding helps the drive regulate current, speed, and thermal loading within normal operating limits. A dedicated shaft seal helps protect the front bearing area from vapor ingress, which supports lubricant retention in demanding work zones. As part of the MKE Synchronous Motors series, the motor uses the same general feedback scaling as matching drives in the platform. This combination supports stable operation in hazardous-duty applications where accurate rotary motion and protected mechanical interfaces are both required.
