The thicker the wire diameter, the more difficult the winding machine winding, whether it is the outer winding machine or the inner winding machine, for the brushless motor wire diameter is a certain requirement, generally more than 1.0 mm is not so good winding, many machines have to non-standard, custom winding machine relative to the general winding machine, will be much more expensive, of course, here refers to the size of the wire diameter, other aspects of non-standard design can not be ruled out. So for example, need to wind 2.0 mm wire diameter, using several strands of wire winding together, the use of general-purpose machines can be solved, and the same effect.
Wound line problem, the thicker the line diameter when winding bending it is easy to scratch the enameled wire skin, easy to cause the wound line situation.
