I think my feeder motor is not suitable...While I was building my ultimaker 2, I had chosen Pololu SY42STH47-1206A (I did not pay attetion at all ). however, its 6 leads and 4v voltage rate.

there are 4 types of "SY42STH47" motors ( http://reprap.org/wiki/NEMA_17_Stepper_motor )

and I need to know suitable version for feeder motor?

SY42STH47-1504A or SY42STH47-1684A / B

there are difference between Holding Torque and motor lenght...

Which one I need to choose?

47 is the motor length. 168 stands for 1.68A which is the one that UM uses. However, the first two letters stand for the manufacturer, so you can have anything there.
