Product Description:
The MKE037B-144-AG1-AUNN is a servo motor developed by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for drive systems installed in potentially explosive areas, the unit converts drive-controller current into precise rotary motion for valve actuators, mixers, and conveyor modules. Its compact frame, winding code 144, and intrinsically safe construction allow integration into classified industrial zones while maintaining the cycle accuracy demanded by automated production lines.
Protection and thermal limits set the operating range of this motor. The enclosure carries an ingress rating of IP 65, sealing the stator against dust entry and low-pressure water jets encountered on washdown lines. Continuous service is permitted from 0 to +40 °C, so temperature-controlled panels are not required in standard plant environments. A preloaded holding brake engages automatically when power is removed, preventing shaft rotation on vertical axes. Position feedback is supplied by an optical encoder identified as model S1, and it uses the single-turn Hiperface protocol to simplify wiring to compatible Rexroth drives. Class 155 (F) insulation withstands winding temperatures up to 155 °C, supporting high current pulses generated by the 144 winding set. Power and feedback terminals are routed on the A-side through a cast terminal box that streamlines armored cable entry in hazardous zones.
The motor includes several mechanical features for direct machine integration. It has a plain shaft with a DIN 332-compliant DS thread on the end face and a front centering hole that simplifies alignment with gearheads or couplings. A positive-lip shaft seal protects the bearings when pressurized wash air is present, and compliance with UL/CSA housing standards assists North American approvals for Class I areas. The encoder delivers 128 increments per revolution, giving single-turn resolution for speed-controlled applications without external gear reduction. Connection direction is fixed to the A-side, allowing predictable cable runs and keeping the terminal box clear of neighboring machine members.
