Product Description:
The MKE037B-144-CG1-AUNN is a servo motor from Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is intended for machinery that operates in potentially explosive areas, where it supplies controlled rotary motion for positioning, indexing, and synchronized speed tasks on automated production lines. The motor works with compatible Rexroth drive amplifiers to provide closed-loop motion control in applications that require accurate response and dependable axis behavior. This makes it suitable for equipment installed near process zones where controlled motion and area compliance are both important.
The housing has an IP 65 rating that blocks dust ingress and low-pressure water jets, allowing mounting close to the process area without a protective cabinet. Its 155 (F) insulation class allows winding temperatures up to 155 °C, which supports repeated duty under changing loads. Reliable operation is specified for ambient temperatures from 0 to +40 °C. Power and feedback conductors enter through a terminal box on the A-side of the stator, which helps route cables neatly in confined machine layouts. Position feedback comes from an optical multiturn encoder with 128 increments per revolution over the Hiperface interface, supporting stable velocity control and repeatable reference moves. The encoder also supplies continuous position data across multiple shaft turns, which is useful on axes that must retain position information during complex motion sequences.
The motor includes a spring-applied, electrically released holding brake that keeps the rotor from drifting when supply power is removed. Torque is transmitted through a plain shaft with a frontal centering hole and a DIN 332 thread, which helps with accurate coupling during installation. An integral shaft seal helps protect the internal bearings and limits lubricant migration. Compliance with UL/CSA construction standards supports use in North American hazardous-location installations. Winding code 144 and the M1 encoder variant match the electrical characteristics expected by compatible drives.
