Product Description:
The MSK050C-0300-NN-M1-UG0-NNNN is a servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers precise torque and position control for automated machinery such as packaging lines, assembly cells, and other coordinated motion systems that depend on repeatable axis behavior. Integrated feedback electronics let the drive controller read absolute shaft data in real time, enabling closed-loop operation and smooth multi-axis movement. That feedback path supports accurate speed regulation during continuous motion and stable positioning when the axis starts, stops, or reverses direction.
Thermal management relies on natural convection, so heat dissipates through the housing without auxiliary fans, which is useful where cabinet airflow is limited or airborne contamination makes forced cooling less desirable. The motor is supplied in the standard design variant, so mounting geometry and surface treatment follow the base MSK configuration used across the product line. For feedback, it carries an optical encoder that offers 128 signal periods per revolution; the light-based sensing maintains stable resolution as temperature changes. The encoder head connects through a 240° rotatable plug, simplifying cable routing in tight spaces. Position, speed, and electronic nameplate data are transferred to the drive over the Hiperface interface. This lets the control system read motor data directly from the feedback channel.
Inside the encoder, multiturn absolute functionality keeps track of shaft revolutions even when supply power is removed, so homing is not required after a shutdown or restart. The mechanical output is a plain shaft sized for frame 050, and the C length supports compact couplings or small gear stages where installation space is limited. Electromagnetic behavior is set by winding code 0300, which balances current demand and usable speed range for general servo duty. Safety-related holding torque must be provided externally because the motor ships without a holding brake.
