Product Description:
The MKE047B-144-AG0-BUNN belongs to the MKE Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as a servo motor for potentially explosive areas, it is used to deliver precise torque and speed control in automation cells where combustible gases or dust may be present. Its design allows tight integration with certified drive controllers for motion tasks such as valve actuation, dosing, or mixing in chemically sensitive zones. In these settings, stable speed regulation supports repeatable motion during dispensing, stirring, and other process steps that depend on controlled acceleration and deceleration.
Power and feedback reach the unit from the B-side, where a compact terminal box concentrates the mains and signal conductors. Rotor position is detected by an optical encoder that provides 128 increments per revolution, carries the S1 designation, and communicates through the single-turn Hiperface interface to give absolute position information at startup. The insulation system is rated for 155 (F), supporting reliable thermal performance during repeated speed changes and frequent duty cycles. The winding code is matched to the electrical characteristics expected by the paired drive, helping the motor respond predictably to current commands while keeping the connection area compact and organized.
For mechanical linkage, the rotor uses a plain shaft with a shaft seal and a frontal centering hole to aid coaxial coupling. Threads follow the DIN 332 "DS" thread pattern so locking screws can be used during assembly, and the shaft seal helps protect the bearing area where splashed material or fine dust may be present near the drive end. The electromagnetic design uses 4 pole pairs for smooth torque production, and the enclosure meets UL/CSA requirements for hazardous-location equipment. The motor is supplied without a holding brake, so holding force must come from external clamping or continuous drive torque.
