Default newbie brushless motor issue...

i have bought a used wraith told needed a stator? (motor smoked) anyways i have orderd and installed the stator but the motor will not run unless i bump it. thinkin the stator could be bad again or i may have got one terminal to hot? when it does run its running rough..
the wraith has a timbuk2 esc and 13.5 turn ballistic motor

first thing is make SURE the sensor cable is seated on both ESC and motor... unplug/replug it. If that does not do it then I'd say either something is bad on the senser board in the motor, you have a bad sensor cable or the ESC has an issue.

Since the motor was smoked my vote is for a bad sensor board in the motor... I think you can replace this board in the ballistic motors.

Try what JSN stated.
If still no good, try recalibrating the ESC to the RX. It's covered in the ESC manual (which is also online.....)

I forgot one VERY important thing... DO NOT TRY AND MAKE THE MOTOR RUN FOR MORE THAN A SECOND OR TWO!!!!! when you have a sensor not reading and the motor shutters runs rough or needs a little help to get going it can/will burn up the ESC!

ok ok so the sensor cable is the 6 prong small wires? and the sensor board looks like its in rough shape, maybe a little melting action went on in there?

Yes that is the sensor wire and yes it sounds like the sensor board is your problem.

Yeah melted sensor board is not good...you can either replace it OR use it for something semi-go fast and run the motor SENSORLESS... your T2 cannot do this.

This is just an easy search... I don't buy much form tower myself.

#1 YES, without the sensors the ESC cannot run the motor correctly.
#2 Possibly, the ESC cannot read the motor rotor position correctly so see #1.
#3 this is because the ESC does not know where the rotor is and cannot start it.
#4 Probably not... just don't try and run the motor any more!!!

Make sure the sensor board you buy is the "crawler" one, your ESC won't function correctly with the normal one.

S5942 is the normal sensor board most places will carry. S5945 is the crawler version. Novak doesn't list the "crawler" one on thier products page, only as a replacement part under the "crawler" motors. You won't have instant reverse or drag brake without it.

As a side note, the S5945 board is all that's needed for a non-"crawler" Novhack motor with replaceable boards to function on a Goat or Timbuk2. Castle and Tekin ESC's don't care which board you use.
