Product Description:

The MSK050B-0600-NN-S1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and placed within the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor converts precisely regulated electrical power from a drive controller into torque and speed for axes that require continuous position feedback, making it suitable for packaging, handling, and small machining stations. The motor combines a rotor-stator design with a high-resolution position encoder, giving the controller exact rotational data so closed-loop motion profiles remain consistent under variable loads.

Heat produced in operation is removed by natural convection, so the motor can be mounted without auxiliary fans as long as ambient airflow is available. Position data reach the drive through the Hiperface interface, which supports digital feedback over a hybrid cable. The scanning head resolves the code disc at 128 signal periods, translating to 2048 sinusoidal increments after interpolation for fine velocity control. Because the sensing principle is optical, there is no magnetized target inside the encoder, which helps reduce hysteresis drift. Its turnover range is single-turn, providing absolute angular information for one mechanical revolution before the count resets and simplifying homing after power cycling.

Mechanical coupling is through a plain shaft, so torque is transmitted by external clamping or keyed hubs without integral gearing. The electromagnetic design uses winding code 0600, which determines the phase resistance and torque constant for this motor variant. Frame designation 050 sets the stator outside diameter, while the B length extends stack height without altering the IEC flange pattern. The motor is supplied without a holding brake, so any vertical axis must rely on drive-based torque or an external clamp when mains power is removed.
