Product Description:

The MKE037B-144-KP0-AUNN is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It converts regulated three-phase drive power into controlled torque and speed, allowing position and velocity control on automated valves, mixers, or pick-and-place axes located in hazardous production zones. Its explosion-protected construction, closed housing, and standardized shaft geometry allow electric motion sources to be used in places where pneumatic drives are often selected. It is suited for machinery that requires repeatable servo motion in enclosed areas where combustible gases or vapors may be present.

The motor is intended for continuous duty in ambient air from 0 to +40 °C, so surrounding conditions must stay within that range during operation. The housing has an IP65 rating, which provides full dust protection and resistance to low-pressure water jets during washdown or paint processes. Class 155 (F) insulation allows winding temperatures up to 155 °C before deterioration. Power and feedback conductors terminate in a terminal box, which supports hard-wired connections in explosion-proof conduit systems. Mechanical power is transferred through a shaft with a keyway, providing positive engagement with couplings that use the DIN 6885 profile.

Cables exit on the A-side, allowing the motor to be mounted flush on the opposite face without obstructing its connection hardware. Conformance with UL/CSA housing rules allows installation in North American hazardous-location panels. The motor is supplied without a holding brake, so applications that require static load support must rely on drive torque or an external mechanical latch. A labyrinth shaft seal helps restrict internal contamination and preserve bearing grease at the shaft entry point. Stator winding code 144 identifies the winding arrangement used for this motor and helps match it with compatible drive settings.
