So the 7i39 is a brush less DC motor, if your trying to see if the motor it self is functional just hook it up to a DC power supply, 12V would do just fine, if it rotates regardless of polarity the motor is good and you need to move onto the electronics. What are you hooking the encoder to? What kind of encoder is it?
