Product Description:
The MSK075E-0300-FN-S2-AG3-RNBN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for closed-loop positioning and velocity control in industrial automation. As part of the MSK IndraDyn S Synchronous Motors series, it uses the 075 frame with E length to provide responsive torque in a compact package. The plain shaft supports direct coupling to gearboxes or driven loads, and the electrically released holding brake helps maintain axis position when the power stage is disabled. This combination suits applications such as pick-and-place axes, tool changers, and conveyor drives.
Heat generated in the stator is removed by liquid cooling, which supports high continuous output without relying on ambient air for thermal management. Rotor position data are transmitted to the drive through the EnDat 2.1 bidirectional interface, and the integrated scale provides 2048 signal periods per mechanical revolution. Because the scanning system is optical, feedback accuracy is not influenced by stray magnetic fields. The encoder is a single-turn device, so absolute position is retained within one mechanical revolution. Power is connected on the A-side, and winding code 0300 identifies the electrical characteristics used by the controller for motor matching.
The motor housing has an IP65 rating, which keeps out dust and resists low-pressure water jets commonly found on production floors. It is rated for continuous operation in ambient temperatures from 0 to 40 °C without derating, and its insulation system meets class 155 for high thermal endurance during cyclic duty. Holding-brake torque is size-dependent, so the available braking force varies with the selected frame. The E-length stator also leaves room for internal coolant passages while keeping the overall motor footprint compact for installation in space-limited machinery.
