I apologize for the following question:..
The actual motor has 3 thick wires blue, green and yellow.
Can the battery be connected to (which) 2 of these in order to see if the motor works or if it is broken? My intention would be to simply.make the motor run.b applying voltage directly to it to see if it is still.working at all.
Or is there another way of checking this out without proper installation?
Many thanks in advance
IIRC, when you spin the motor shaft by hand with all the wires disconnected as well as disconnected from each other, it should feel like it is "sitting" / or "plopping" into place in multiple points as you rotate it (the magnets attraction on the rotor is noticeable). If you then short the wires together, the motion as you turn it should feel completely smooth, i.e there is no more "magnetic" feeling as you turn it, and I think it feels stiffer to turn too. If you short just two wires together its something in between.
You can also test with a multimeter, to see if the readings between phases seem sensible, I believe all combinations of wires should show a similar resistance.
Don't apply DC, that may cause the magic smoke to escape and fry the motor. It's a brushless (not-really)-DC motor, which requires a controller to turn DC into synchronized three phases to make it turn.
