I know how to reverse a single phase induction motor. I also try to understand it using this link. But, I can't understand how to reverse the motor of fallowing wiring diagram. In this diagram, RED and BLUE terminals connected to TRIAC separately.

wiring diagram

How this motor start,stop,and change direction according to this diagram? How about internal connection to the winding of this motor?

    \$\begingroup\$ Old fashion washing machine motors are specially made to reverse directions for washing then spinning the load. I don't know if this applies in this case, but I found this on the net: "In a single phase induction motor, the direction is controlled by a starting capacitor. Change the pole on which it it placed will reverse the direction it starts and then runs in." I found it here. \$\endgroup\$ – st2000 May 26 '17 at 11:40

It seems very likely that you have something like the connection of the question linked in your comment. You likely connect power to blue and yellow for one direction and red and yellow for the opposite direction.

You probably can not determine for sure what you have without testing. Connect the motor through a switch that you can turn off quickly if there is a problem. It would be good to check the current with an ammeter before running the motor for more than a few seconds.
