Hello.  
I got my motor today from aliexpress, that i think is faulty.  
Motor spins but heats eaven with no load applyed to shaft.  
It is not hot but warm on touch.  
I tested it with 20v battery on my red brick 200 A esc.  
Thing that bother me most is uneaven winding inside motor ( opend motor, so i can design gerbox mount easyer)…

The heat comes from the eddy current losses, everything OK.  
The winding also looks normal.
