The R911277948 (MKD112B-073-KG1-AN) servo motor from Bosch Rexroth is built for industrial automation applications and features IP65 ingress protection for use in demanding environments. The motor utilizes sealing air connectors to prevent the ingress of cooling fluids and lubricants, supporting stable overpressure within the housing. It is equipped with a built-in PTC temperature sensor for continuous motor winding temperature monitoring. The unit operates with natural convection cooling by default, with optional blower capability for enhanced performance. Designed for use at elevations up to 1000 meters, it employs class F insulation rated for operation up to 311°F. This model features a plain shaft with a shaft seal and includes a 22 Nm electrically releasing holding brake for secure axis retention during power-off conditions. The integrated resolver encoder supports absolute position detection beyond 4096 revolutions. Key specifications include a 28.0 Nm continuous standstill torque, motor length B, 192 mm flange size, 130 mm centering diameter, 50 kg weight, 400V operation via a terminal box, and standard cooling configuration.
