The motor lead wires are connected to the winding home wires and lead out to achieve the wiring fixing of the motor itself, providing the customer with the necessary wiring elements via the terminal board. There are also some motors with longer leads that do not use a terminal board, but the end-of-line marking of the lead wires is necessary.
For the lead part, there are three links are most prone to problems: First, the lead and the winding line of the welding position, how to achieve the two welded firmly, and to solve the position of the winding resistance of the impact is very critical; Second, the lead out of the process of the lead line, because it is necessary to lead from the motor's internal cavity through the casing, if there is a sharp casting of the casing fret, it is easy to lead to the insulating sheath of the damage caused by the failure of the ground; Third, is the connection between the lead and the end of the head, the actual operation process, there are problems including peeling off the sheath when the lead conductor cut off, part of the lead conductor fails to enter the end of the head tube hole, especially the two unreliable connection problem is more serious.
All of the above are easy to occur at the operational level of the problem, of course, the use of stable quality of the lead wire is to ensure that the quality of this link is a necessary condition for reliable.
