Hello fellow users, its me again.
I was talking with a friend about electric motors and their applications for transportation (small EV conversions and such), and he brought the idea of using multiple small BLDC motors coupled/welded together in a single mechanical shaft to move, instead of choosing a single bigger motor.
The idea seemed interestng at that moment and i told him that i was gonna check some materials and contect on the internet about this, and for induction motors like the HPEVS lineup (AC34X2), and series wound motors (like a lot of drag racing machines and other EV conversions, being locked in a single shaft or connected indirectly by gearboxes or chains), but i can't find much information about it with BLDC motors, if it's okay to do it or if its gonna break something, or in a minute or in a year. But i have found a video where the guy uses two motors physically connected and two separate controllers to move a car, like my friend told me.

In this video, the guy simply connect both motors together and wire them with their sensors to the separate controllers, but one of the motors gets two phases shifted, but i couldn't tell if it was because he connected the second motor back-to-back with the first or if he knew something i still need to learn.
I hope someone here can help me with that. No specific motor model was chosen, his only idea was to have 2 or more BLDC motors mechanically coupled, most certainly sensored motors to be sure of the correct working under load.
