Product Description:

The MKE116D-027-NP0-KN is a three-phase servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. It is intended for hazardous-area machinery and is designed to work with an approved drive controller that governs torque, speed, and position during automatic machine operation. In an automation line, the motor supplies repeatable torque to rotary actuators, indexing tables, or pump shafts while meeting ignition-source limitations required in chemical, paint, or grain-processing facilities. It is used where controlled motion must be maintained in areas that can contain flammable vapors or combustible dust.

Its electrical winding is coded 027, which indicates the stator wire gauge and turns count used for the motor’s nominal voltage, current, and back-EMF characteristics. Motor cabling enters from the top, so routing can follow vertical trunking inside the enclosure. Power and feedback leads terminate in a terminal box, providing screw-clamp connections that resist vibration better than feed-through plugs. The model is delivered without a holding brake, which reduces length and inertia but requires external means to secure a stopped axis. As a servo motor for potentially explosive areas, it is built for use where ignition-source control is required.

Mechanical coupling is through a shaft with keyway, allowing positive torque transfer to standard hubs. The key follows the DIN 6885 keyway profile, so matching components can be installed without additional fitting. There is a shaft seal, which helps limit dust or oil ingress along the journal and supports the motor’s protective sealing when it is mounted to gearboxes. A keyed shaft is useful where the load must transmit torque through a positive mechanical connection instead of relying only on friction from a clamp-style hub under changing load conditions.
