Hello, Can any one guide me to find circuit for 12VDC BLDC Motor which can handle at least 1A current. :o
That's probably not what you want. Can you give us more information on what you're trying to do?

Using GOOGLE, there are 564 HITS already on this fourm ...

Did you read any of them?
I have one radar motor and it's unidirectional. I need to make it as bidirectional motor. I found controller in side motor. and winding are star connected.
One of these?
@ MorganS,
Ha , ha, isn't that classified military equipment ? (I don't think he could afford it anyway)
As far as posts about BLDC drivers or ESCs as they are known in the RC world, the only ones I know that are bidirectional are the ones used in the camera gimbals. I think we need mass specs for the load.
What motor are you talking about ? I haven't found any bidirectional brushless motor controllers in any forum posts and the only ones online are camera mount gimbal motor controllers.

If you swap two of the three phase wires ( with a relay ? ) won't the motor spin in the opposite direction?

What motor? What winding resistance? Does it have hall-sensors? Do you want speed, torque and/or position control?

Yes, but you can't do it under power. You have to deenergize the motor driver before energizing the relay.
Thank you for replying. I'm not having that type of militatry radar. but one of these. 
The picture is not displaying for me.
check this..
Now if the motor nameplate were legible that would be useful... I can't even confirm if it
has 3 wires from this fuzzy picture.

And that is why I also provided a link to a Bi-Directional IC.
The link is broken.
