Product Description:

The MSK050C-0300-NN-M2-UG1-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As an IndraDyn S synchronous servomotor, it provides closed-loop rotary motion for positioning and speed-controlled axes in automated machinery. Its design supports accurate speed regulation and repeatable positioning in equipment that depends on fast response and stable servo performance during continuous operating cycles.

This motor relies on natural convection to remove heat from the stator, so it can be installed without forced-air fittings when ambient airflow is available. A plain shaft is supplied to simplify coupling, and the rotor is manufactured with increased concentricity to reduce radial runout in high-precision drives. Feedback data are transferred over the EnDat2.1 serial interface, while the optical encoder inside the housing resolves motion into 2048 signal periods per mechanical revolution. The windings use code 0300 and are matched to the C-length stator segment in the 050 frame size, which helps balance torque density with a compact overall length. For power-off load retention, an electrically released holding brake supplies 6 Nm of static torque. The motor is sealed to IP65, so it resists airborne dust and water jets during normal plant washdown routines.

The encoder connector is rotatable through 240°, allowing cable exits to align with surrounding machine layouts and reducing strain on the connection. Position information is retained after loss of supply because the feedback unit is a multiturn absolute encoder that counts complete revolutions without battery support. Optical scanning produces low-jitter signals, and the stator insulation system is rated for a maximum winding temperature of 155 °C to withstand repetitive thermal cycling. Continuous service is specified within an ambient range of 0–40 °C, which keeps the motor within its intended operating window during routine industrial use.
