As shown in the figure below, this article describes an electrode auto-regulator circuit for a motor that has better performance. In the figure, BQ is the clutch motor excitation winding; TG is the tachogenerator, and BQTG is the tachogenerator field winding. For example, a current-output bridge type comparison circuit with high accuracy and good linearity is adopted; an arc current differential negative feedback circuit (leader) is adopted, so that the lead time and the correction intensity are adjustable, and no overshoot phenomenon is caused.
