Abstract
This report first explains a prototyped constant current control circuit, which has successfully realized constant amplitude of the stator tip while maintaining a state of resonance, and that leads to the experimental results of velocity reduction proportional to the load torque under the constant current drive. Secondly, a new friction model based on these findings is proposed.
