Okay so this is what I have:

Now when I wire those three leads in any combination possible all I get it a motor that wiggles a quick second and is locked in position. Just like you’d see if you wired an AC motor with DC power...

 

Aaaaaaand I’m pretty sure that’s exactly what this is... a brushless 3 phase AC motor.

 

Definitely can’t use that...

 

After some research the module there is controlled by a PWM signal that varies in voltage and frequency to control speed and duty cycle.....

 

Definitely can’t use that...

 

Wasted $60.
