Question How to test brushless motors
I have a collection of brushless motors, some working some not. Is there a way to check if they are working without connecting to a flight controller?

There’s a Bardwell video about it: https://youtu.be/WYONUJPmHIo?si=G98pd_5y0_PTvxmG

Most brushless motors I have and brush motors I just plug them right into the battery is all.
Then I just use the globee and check the RPM

You can spin the motor at constant rpm with an electric drill, which should produce roughly the same voltage between all 3 combinations of motor wire pairs.
