Product Description:

The MSK050C-0450-NN-M2-UP0-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Classified by the manufacturer as an IndraDyn S synchronous servomotor, it is applied in automation axes where closed-loop torque and position control are required. The unit converts electrical energy from a drive controller into mechanical motion with high positional accuracy, supporting tasks such as feeder drives, pick-and-place heads, and compact packaging machinery.

Thermal management relies on natural convection, so all generated heat leaves the housing without forced airflow. The frame is motor size 050 with the longer C length, and the internal winding carries code 0450. Position feedback uses an optical encoder, and the connector is rotatable through 240°, allowing cable exit to be aligned after installation. Data are transmitted through the EnDat2.1 digital interface, while the scanning head resolves 2048 signal periods per mechanical revolution for fine interpolation during drive regulation. The shaft is produced with increased concentricity to limit runout, and the motor is supplied without a holding brake, so any static load must be restrained by the drive or external mechanics.

The encoder records turns beyond a single rotation because its counting method is multi-turn absolute, removing the need for a reference move after shutdowns. Environmental protection meets IP65, so dust and low-pressure water jets cannot reach the windings or feedback electronics. The motor can run continuously in ambient temperatures from 0–40 °C, and insulation class 155 maintains dielectric strength under the resulting thermal rise. A shaft with keyway delivers a secure drive-to-load connection, permitting straightforward coupling to belts or gears. The C-length rotor is dynamically balanced for minimal vibration, allowing stable operation at commanded speeds.
