Product Description:

The MKE116B-024-NG0-KN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Engineered for use in potentially explosive areas, it transforms drive controller output into controlled rotary motion for pumps, mixers, or positioning stages that must comply with hazardous-location regulations. By pairing flameproof construction with precision rotor dynamics, the motor provides safe torque generation for industrial automation lines that require continuous duty inside zone-rated enclosures.

The wiring leaves the housing at the top, so conduits can be routed upward and liquid ingress points can be kept away from the shaft seal plane. All power, signal, and protective earth leads terminate in a cast-on terminal box, which allows access to the connections without disturbing the mechanical mount. Motion is transmitted through a plain shaft, a design that avoids keyway stress risers when the driven element is shrink-fitted. A frontal centering hole is machined into the shaft face to support alignment during assembly and balancing. For positive axial retention, the end of the journal carries a DIN 332 DS thread, which allows a puller to extract the coupling component without axial hammering that could damage the bearings.

This motor is classified as a servo motor for potentially explosive areas, meaning its stator insulation and enclosure clearances are suited to ignition-risk requirements rather than relying only on purge systems. It is supplied without a holding brake, so position must be maintained by the drive or an external clamp during power loss. There is a shaft seal on the output end to block oil, dust, or gas from migrating along the shaft bore into the interior windings. The stator uses the 024 winding code, which matches the electrical characteristics to compatible drive inverters operating at rated voltage and frequency without exceeding current limits.
