The circuit is shown as the figure. After the speed winding LD and auxiliary winding LA are connected in series, then they are connected between main winding LR's tap and power supply. LD and LA are in the same groove with the same phase. Speed control principle: the circuit make LR upper part, the second part and auxiliary winding LA part form inconsistent-phase three asymmetric phases.
