Product Description:

The MKE037B-144-CG1-BENN is a servo motor from the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a servo motor for potentially explosive areas, it is intended for motion axes that must operate safely inside hazardous zones while maintaining precise speed and position control. Its electrical winding code 144 and the plain shaft with a frontal centering hole allow the unit to couple directly to gear stages or load elements used in automated filling, mixing, and conveyor stations. The design supports controlled starts, stops, and speed changes in enclosed process equipment where consistent axis response is important.

Hazard location suitability comes from its ATEX-certified housing and an enclosure protection rating of IP 65, so dust and low-pressure water jets are kept away from internal components during washdown cycles. The ambient operating window is 0...+40 °C, and internal insulation materials meet class 155 (F), permitting winding temperatures up to 155 °C without insulation breakdown. For load holding when power is shut off, the motor is equipped with a holding brake; this mechanical element secures vertical or torsion-loaded axes and reduces the need for external clamps. The sealed housing also helps limit contamination when the surrounding process releases fine particles or vapors.

Position feedback is delivered by an optical multiturn Hiperface encoder that provides 128 increments per revolution. It carries the manufacturer’s M1 designation and gives the drive controller absolute position data over several shaft turns. Power and signal conductors enter through a terminal box mounted on the B-side, which simplifies wiring inside flameproof junction enclosures. A shaft seal limits vapor ingress, and the output end follows a DIN 332 "DS" thread so assembly tools can lock the rotor during service.
