Product Description:
The MKE047B-144-GG0-AUNN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor certified for use in potentially explosive areas, where it drives positioning or speed-controlled axes without introducing ignition sources. It converts drive commands into controlled rotary motion for positioning and speed-regulated axes in hazardous-zone conveyors, mixers, and dosing equipment. Its flameproof construction and precise mechanical fit allow the motor to be installed where accurate closed-loop motion is required in areas that demand explosion-protected equipment.
Electrical interfacing is arranged on the A-side of the housing and is routed through a terminal box that simplifies armored cable entry. This layout keeps the connection point concentrated on one end of the motor and supports orderly cable routing in enclosed machine sections. The stator uses winding code 144, which matches the electrical characteristics expected by compatible MKE drives and helps limit copper losses. The motor uses 4 pole pairs, which support stable torque at moderate base speeds. The winding system is built to insulation class 155 (F), allowing the winding temperature to reach 155 °C within the class limit, while a shaft seal helps keep oil or dust away from the bearing cavity.
The cast housing carries the UL/CSA marking for hazardous locations, supporting installations that require North American approvals. The motor is supplied without a holding brake, so any load that must remain fixed during power loss needs external restraint or drive torque. Output torque is transmitted through a plain shaft that includes a DIN 332 “DS” thread for extraction tools, which allows pullers to engage the shaft end during service. A frontal centering hole at the shaft face helps align couplings, flanges, or pulleys during installation.
