Product Description:
The MKE047B-144-CP0-AUNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is classified as a servo motor for potentially explosive areas, making it suitable for motion axes located in hazardous zones of process-plant or paint-line installations. The unit supplies rotational power to drives that require compact dimensions, certified housing, and integrated position feedback so that speed and torque can be closed-loop controlled by an external inverter.
The cabling interface is oriented on the A-side, and connections are completed through a terminal box that simplifies hard-wired routing inside flameproof enclosures. Position data are provided by an optical feedback system identified as model M1; this device resolves rotor position in 128 absolute increments and communicates through the multiturn absolute Hiperface protocol, allowing the controller to track multiple revolutions without battery backup. Electrical behavior is set by winding code 144, which matches the stator’s impedance to compatible drive converters and helps keep current within safe limits while still delivering the rated torque envelope.
The motor is supplied without a holding brake, so mechanical load holding must be handled externally when power is removed. Its cast-iron housing meets UL/CSA construction standards, and the stator insulation is rated at 155 (F) for thermal endurance during continuous duty. The rotor uses 4 pole pairs, giving the drive a balance between torque density and electrical frequency. A shaft with a DIN 6885 keyway transmits torque to couplings, and a shaft seal helps limit oil or dust ingress at the front bearing. The design follows class-conformant clearance rules so that motion control can be implemented in explosive atmospheres without compromising safety certificates.
