Product Description:
The MKE037B-144-CP1-BENN servo motor is manufactured by Bosch Rexroth Indramat and is part of the MKE Synchronous Motors series. Designed as a motion element for potentially explosive areas, it drives actuators and conveyor sections that must meet ignition-risk regulations. An optical multi-turn encoder with the Hiperface interface keeps absolute position data, allowing the connected controller to resume operation without homing after a shutdown. This motor is suited for chemical mixers, filling equipment, and paint lines where precise closed-loop positioning is required.
The motor operates in ambient conditions from 0 to +40 °C, and staying inside this range helps the windings and bearings meet expected service life. Its enclosure carries an ingress protection rating of IP 65, meaning dust-tight construction and resistance to low-pressure water jets, so the housing can be washed down without additional covers. Compliance with ATEX housing standards certifies the exterior for use in Zone 2 or Zone 22 installations. The stator insulation is rated at 155 (F), allowing internal temperatures up to 155 °C before thermal aging accelerates. A factory-installed holding brake secures the load during power loss, eliminating the need for external mechanical locks. A shaft seal is fitted to limit vapor ingress through the front bearing, and electrical power enters through a terminal box that accepts armored conduit for wiring in classified areas.
Cabling is routed on the B-side of the frame, simplifying junction-box alignment inside a cabinet. The feedback system delivers 128 increments per revolution to the drive, and encoder model M1 provides multi-turn data so the shaft angle and revolution count are retained continuously. Mechanical power is transferred through a shaft with keyway machined to DIN 6885, giving positive torque engagement with couplings or pulleys. Stator winding code 144 corresponds to the electrical resistance and inductance that the compatible Rexroth drive must match for rated current control.
