Product Description:

The MSK060B-0300-NN-S1-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This motor is used on coordinated axes that require precise torque and velocity feedback for packaging, material-handling, or light machining equipment. When paired with a compatible drive, it supports closed-loop motion that keeps speed and position stable as load conditions change. Its length class is B and its winding code is 0300, which gives the motor a mid-range torque constant within the standard mechanical envelope of the series.

Heat is removed exclusively by natural convection, so cabinet airflow must remain unobstructed for the aluminum housing to dissipate losses. The encoder plug is rotatable through 240°, allowing the cable exit to align with available raceways and avoid tight bend radii. Position data is sent to the drive over the Hiperface digital channel, which carries both commutation and electronic identification information and reduces wiring compared with analog tach feedback. Inside the feedback module, an optical disc provides 128 signal periods per mechanical revolution. The light-gate scanning method uses an optical pickup, which provides high immunity to magnetic stray fields without additional shielding.

The feedback device measures absolute rotor angle over a single turn and is classified as single-turn, so multi-turn counts must be handled in the controller when the application requires them. Mechanical coupling uses a plain shaft, which supports backlash-free clamp hubs where a keyed connection is not needed. The stator lamination height and frame diameter correspond to motor size 060, allowing installation in 60 mm pitch mounting grids used for compact servo axes. Because the unit is supplied without a holding brake, static load retention must rely on drive torque or an external locking element when power is removed.
