Actually the motor will run continuously and after a dealt of 2 second relay should triggered and open the circuit so that motor will not run until main power supply is off. Timer will reset when main PS is off.
Adjustability. You can dial in the exact time you want the delay to be.what is the role of 22K pot
No! 100 uF capacitor and the 47K resistor,Means changing 100uf capacitor and 2K resistor can vary the delay time right? But then what is the role of 22K pot Mr. Dodgydave is saying about?
Yes I want the motor to run for 2 seconds then shut down until power resets.Adjustability. You can dial in the exact time you want the delay to be.
Quick question for you: You want the motor to run for (oh, lets say) 2 seconds then shut down until power is recycled? Or do you want the motor NOT to run for 2 seconds then start up afterwords?
Yeah 2 second is not necessary 5 seconds will work fine.Why 2 seconds? Can you live with 4 or 5 seconds or slightly longer? How tightly are you constrained to 2 seconds?
 Well I suppose that's a moot point. With the circuitry DodgyDave gave you - that should solve your problem. You can precisely dial in the delay with the pot.
But your circuit isn't using 555 IC. I want to built whole circuit with 555 IC only. Thanks for advice.Followup thought on the circuit I provided: if you're powering the relay from a low voltage source such as 12 volts and want to switch a motor running at high volts AC then the relay you'll want to use will have to be a double pole double throw type so you can isolate the high voltage from the low control voltage circuitry.
