Product Description:

The MKE047B-144-CG1-LUNN is a servo motor for potentially explosive areas from Bosch Rexroth Indramat and is part of the MKE Synchronous Motors series. It provides closed-loop position and speed control for automation axes that must meet hazardous-location requirements while remaining compatible with matching drive controllers. The motor uses winding code 144 and a multiturn optical encoder to supply the feedback needed for coordinated motion tasks. This combination makes the unit suitable for applications where controlled motion and safe operation are both required.

The housing meets UL/CSA requirements, and its windings use insulation rated to 155 (F), supporting thermal durability when the frame is installed in sealed enclosures. The motor has 4 pole pairs, which support strong torque production at moderate electrical frequency in process machinery. The encoder provides 128 increments per revolution and uses the M1 design with a Hiperface interface, allowing precise position tracking over multiple turns. For static load holding or emergency stops, the integrated brake provides 2.2 Nm of torque and engages automatically when power is removed. This arrangement helps the axis retain position without requiring an external holding device.

Cabling is routed through a terminal box on the left connection side, which helps when cable entries must be aligned in rows. Mechanical output is transferred through a plain shaft that includes a frontal centering hole for face-mount couplings, and its end is tapped with a DIN 332 'DS' thread for extraction tools. A shaft seal is fitted to help limit the ingress of dust or oil. The encoder’s multiturn function uses an internal gear mechanism instead of batteries, so position information is retained without a battery-backed system. The motor body is built for use in hazardous areas, and the winding arrangement is matched to the electrical characteristics expected by the associated inverter.
