Textile machine automatic control circuit

In the circuit as shown in the figure, VS is a bidirectional thyristor, R1 and C are absorption loops, and R2 is the trigger limiting resistance. K1 is the start reed switch, K2 is the stop reed switch, Y1 and Y2 are magnets. Split-phase power supplies L1, L2, and L3 are added to the motor M via VS1 to VS3. When driving, push the clutch handle to move Y1 to the starting position, the internal contact of K1 is connected, triggering the conduction of VS1~VS3, and the motor M is energized to work; when parking, the self-stop magnet Y2 installed on the clutch handle is close to K2 , the normally closed contact inside K2 is disconnected, the trigger circuit is powered off, VS1 ~ VS3 are cut off one after another, and the motor M stops.
