My drone has a newly purchased electric motor that burns in a few minutes and doesn't dare to crank it up to full speed.And at low speeds, the revs are noticeably slower than the other three.
What causes it?Is the motor and electrical regulation of the connection problem, or is the reason for electrical regulation?

Perhaps something is blocking its spin or one or more screws touching its windings. And pls make sure the esc is ok (may be by swapping them once)
