Product Description:
The MKE047B-144-CG0-BUNN servo motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is classified as a servo motor for potentially explosive areas, so it provides controlled torque and speed for automation tasks that must meet strict safety requirements in hazardous zones. By converting drive current from a compatible controller into precise mechanical motion, the unit positions actuators, pumps, and material-handling equipment with repeatable accuracy in process plants and manufacturing cells. This allows the motor to serve applications that need both precise axis control and suitability for hazardous operating environments.
Electrical interconnection is routed on the B-side, and power plus signal conductors land in a terminal box, which simplifies armored cable entry in flame-proof enclosures. Rotor energization is matched to winding code 144, giving voltage and current characteristics suited to compact drives in the 047 frame size. Position feedback is delivered through a multiturn absolute optical Hiperface encoder; its output is quantized into 128 counts per revolution by the internal M1 measuring system, allowing the drive controller to monitor absolute shaft angle over multiple turns without battery backup. Absolute position feedback also helps the control system recover machine position after a power cycle without relying on a separate homing routine.
The motor uses a UL/CSA-compliant housing for North American approval requirements. Insulation class 155 (F) allows winding temperatures up to 155 °C during cyclic operation. The rotor has 4 magnetic pole pairs, which set the synchronous relationship between electrical frequency and rotor speed. It has a plain shaft with a frontal centering hole, a DIN 332 DS extraction thread, and a fitted shaft seal that helps block dust or vapor ingress along the journal. Because the motor is supplied without a holding brake, external restraint is required whenever power-off holding torque is needed.
