Product Description:
The MKE047B-144-AG1-AUNN belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat. It is a servo motor intended for potentially explosive areas, providing closed-loop rotary motion in hazardous-zone drives where precise speed and position control are required. The motor uses winding code 144 and meets UL/CSA housing requirements, allowing installation on machinery exported to North American sites that require those compliance marks. Its application range includes process equipment that must maintain accurate motion while operating within safety requirements for hazardous locations.
The wiring interface is placed on the A-side of the frame, and power and feedback conductors terminate in a terminal box that simplifies armored cable routing inside flame-proof conduits. Position feedback is supplied by an optical encoder with 128 increments per revolution, and its model designation is S1. Because the sensing element uses the single-turn Hiperface protocol, it can exchange electronic data with compatible Rexroth drive controllers. This arrangement supports stable feedback transmission over the longer cable runs often found in pump modules, agitators, and dosing stations used in chemical processing zones. The terminal arrangement also keeps the connections grouped in one enclosure, which helps organize separate power and feedback leads.
A permanent-magnet rotor is paired with a holding brake that provides 2.2 Nm of static torque to secure vertical axes when power is removed. Motion is produced by a rotor layout with 4 pole pairs, which supports smooth torque delivery across the operating range. Class-F insulation rated at 155 (F) supports continuous duty where ambient and enclosure temperatures rise during service. The plain shaft includes a frontal centering hole and a shaft seal to help limit vapor ingress, and its threads follow the DIN 332 'DS' thread pattern so clamping screws can be used for pulley removal or coupling extraction. That shaft format suits direct coupling arrangements where secure axial positioning is needed.
