Product Description:
The MSK061C-0300-NN-M2-UG0-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a torque-producing axis unit, it converts electrical drive commands into precise rotary motion for packaging lines, pick-and-place gantries, and other position-controlled machinery in industrial automation. When paired with a compatible drive, it supports closed-loop motion tasks that require repeatable positioning and stable speed control. This makes it suitable for automated equipment that runs frequent motion cycles and depends on accurate rotary response.
It handles heat through natural convection, so thermal energy leaves the frame without auxiliary fans and cabinet airflow remains simpler. An optical encoder using the EnDat2.1 serial interface feeds position data directly to the drive controller. The sensor delivers 2048 signal periods per revolution, providing small incremental angles for accurate velocity control. Because the encoder is multi-turn absolute, shaft orientation across several mechanical turns is retained even after a power loss, eliminating homing routines at startup. Environmental protection reaches IP65, preventing dust ingress and resisting low-pressure water jets. A rotatable 240° connector helps route the feedback cable in dense machine layouts, and motor length code C with size 061 keeps the housing compact for multi-axis assemblies.
The motor has increased concentricity, so radial runout at the coupling face stays within tight tolerance during high-speed motion. Its plain shaft accepts clamp hubs or collets without keyway backlash. This shaft style is commonly used where couplings rely on frictional clamping rather than keyed engagement. Winding code 0300 matches the electromagnetic constant to standard drive currents, and insulation class 155 allows elevated winding temperatures during cyclic duty. Continuous service is permitted in an ambient range of 0 to 40 °C. The unit is supplied without a holding brake, so external locking devices must secure vertical loads when power is removed.
Frequently Asked Questions about MSK061C-0300-NN-M2-UG0-RNNN:
Q: What type of cooling does the MSK061C-0300-NN-M2-UG0-RNNN motor utilize?
A: The MSK061C-0300-NN-M2-UG0-RNNN uses natural convection for cooling, operating efficiently without the need for forced air or liquid cooling.
Q: What type of encoder and interface does the MSK061C-0300-NN-M2-UG0-RNNN motor feature?
A: This motor is equipped with a multiturn absolute optical encoder with a resolution of 2048 signal periods and EnDat2.1 interface.
Q: What is the protection rating of the MSK061C-0300-NN-M2-UG0-RNNN?
A: The protection rating for this model is IP65, meaning it is fully protected against dust and low-pressure water jets.
Q: Is a holding brake included on the MSK061C-0300-NN-M2-UG0-RNNN motor?
A: This motor is manufactured without a holding brake, so it does not provide braking force when powered off.
Q: What type of shaft does the MSK061C-0300-NN-M2-UG0-RNNN servomotor have?
A: The plain shaft design provides a smooth surface for coupling without a keyway or additional shaft features.
