Servo motors can be subject to torque disturbances that may impact the required motion performance of your system. There is a great deal of hype in the marketplace about “zero-cogging” motor designs, leading many to believe that zero-cogging equates to zero torque ripple. By understanding the physics behind servo motor torque disturbances, you can make better design choices for your motion control system.
In this session you will learn:
- The physics of servo motor operation that lead to torque ripple and impact the quality of motions including cogging torque, armature reaction, and other harmonic distortion effects.
- Strategies for mitigating cogging torque in servo systems.
- Motor design impacts on torque ripple.
