Product Description:
Bosch Rexroth Indramat’s MSK050C-0600-NN-M3-UG1-NNNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. Built in the standard design variant, the motor couples directly to machinery through a plain shaft and delivers closed-loop control when paired with Rexroth drive electronics. In automated packaging lines, material-handling gantries, and small machine tools, it supplies rapid yet repeatable motion, enabling high throughput without external mechanical gearing. Its synchronous operating principle supports accurate speed regulation and consistent positioning during frequent starts, stops, and direction changes. That behavior is valuable in cyclic automation where short move times and repeatable path control matter more than raw top speed alone.
The MSK050 platform uses size 050 with length code C, so the active magnetic stack balances torque against a compact envelope. Heat generated by the 0600 winding is released through natural convection, eliminating auxiliary fans. This cooling method keeps the installation simple and avoids moving extra air through the motor area. A housing rated IP65 blocks dust ingress and water jets, making the motor suitable for direct mounting on the machine within the 0 to 40 °C ambient range. The encoder connector can be rotated through 240°, which helps route cables cleanly when space around the motor is limited. Position data moves to the controller via the Hiperface serial interface, and the multi-turn absolute encoder subdivides one mechanical revolution into 16 signal periods so the drive can process fine motion changes at low speed. The compact body also helps the motor fit tightly spaced axes without forcing oversized brackets or guards.
The feedback system employs capacitive scanning, which tolerates high vibration and magnetic fields while keeping resolution stable over multiple turns. An electrically released holding brake is integrated on the motor’s non-drive end and provides 6 Nm of static torque, so the shaft can remain fixed when power is removed. This arrangement is useful on vertical axes and other applications where the load must stay in position during a stop. The brake function complements servo control by preventing unintended drift while the mechanical system is stationary. For thermal endurance, the windings comply with thermal class 155, supporting elevated winding temperatures during prolonged high-load cycles without compromising insulation integrity.
