Product Description:
The MKE037B-144-KG0-RUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for motion tasks in potentially explosive areas, it converts electrical power into controlled rotary movement for conveyors, pumps, and positioning axes that must meet hazardous-location rules. The motor’s flame-proof construction, certified clearances, and closed-loop duty enable accurate speed and torque regulation inside classified industrial zones. This layout allows the motor to deliver controlled motion while keeping ignition-capable electrical parts enclosed from the surrounding atmosphere.
Installation limits are given by several operating figures. An ambient range of 0...+40 °C indicates the surrounding temperature the winding can endure without load reduction. The enclosure rating of IP 65 seals the stator against dust and water jets, permitting direct mounting on open machinery. Class 155 (F) insulation allows continuous winding temperatures up to 155 °C before dielectric aging accelerates. Power and feedback conductors terminate inside a terminal box, providing screw-clamp access for armored conduit. All cable exits point to the operator’s right, which helps keep routing consistent across repeated machine sections.
Compliance with UL/CSA standards supports use in installations that require North American approval for hazardous locations. The rotor carries a plain shaft that includes a frontal centering hole for balanced coupling, and a DIN 332 compliant "DS" thread that accepts puller tools during service. A shaft seal is fitted to block washdown fluid from the bearing cavity, and the centered shaft geometry helps maintain accurate coupling alignment. Because the unit is supplied without a holding brake, external mechanical locks or drive torque must secure the load during power loss. Winding code 144 corresponds to the resistance and inductance values expected by matched IndraDrive amplifiers, which helps maintain smooth sinusoidal current and low torque ripple.
