Those are of course brushed DC motors.
I know that BLDC motors require more complex controls to spin up as opposed to just being hooked up to a DC source. However, I am curious if two BLDC motors would behave in the same manner as long as the two motors are identical, thus assumedly having matching phases. Then U would simply be connected to U, V to V, and W to W.
If it is indeed possible, would it also be possible to reverse the direction of the powered motor? How would the U, V, and W terminals need to be reconnected?
To clarify, this is not for any ‘free energy’ purposes, I am fully aware that there would be efficiency losses.
Thank you in advance for any help.
