Product Description:
The MSK050C-0300-NN-S1-UG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended to supply closed-loop torque and position control to automation axes in packaging machines, material handling lines, and other CNC or PLC-based systems. Its compact format supports repeatable angular accuracy without excessive footprint.
Heat from the stator is removed by natural convection, so the motor relies on surface area and ambient airflow rather than forced fans. This arrangement simplifies wiring and reduces maintenance where cabinet ventilation is available. The housing follows the standard design classification, so mounting geometry and connector positions match MSK units. For feedback, the encoder connector is rotatable through 240°, allowing the cable exit to be oriented within a wide arc inside tight cabinets. Signal exchange with the drive controller occurs over the Hiperface interface, which carries incremental and absolute position data. Position feedback is generated by an optical scanning head with 128 signal periods, giving the controller consistent interpolation points for smooth velocity loops.
The encoder uses a single-turn arrangement, so the absolute position reference resets after one mechanical revolution. This is suitable for short-stroke rotary axes that home through limited travel. For load holding when power is removed, an electrically released brake supplies 6 Nm of static torque and engages automatically on shutdown. Mechanical power is transmitted through a plain shaft, which avoids keyways that could introduce backlash in clamp or collet couplings. The motor uses frame size 050 with length C, and winding code 0300 indicates the wire gauge and turn count selected so current demand matches common IndraDrive amplifier ratings.
