What is the requirement of stator slot for automatic brushless BLDC stator motor coil inner needle winding machine?

With the high-speed development of brushless motor, supporting the stator winding equipment is also more and more advanced, the degree of automation is increasingly high, many motor stator slot inward, usually using the hook and pin internal winding machine to solve the winding problem, in addition to the stator outside diameter, inside diameter, wire diameter, single line and other parameters, there is a more important parameter is the slot distance, then the automatic brushless motor winding machine on the stator slot what Vacuz gives you a brief analysis of it!

Motor manufacturers for the stator design is more careful, slot distance is also very critical, some products require a smaller gap, so the design is smaller, or even less than 1.5mm, then there is a problem, that is, not taking into account the winding equipment, the details are as follows.

1. slot 1.5mm or so, the needle can barely enter the slot, so it is easy to hurt the line, scrape the line or even break the line, debugging is very troublesome, the requirements for the precision of the machine is very high, the stability also requires high.

2. Slot less than 1.5mm, the needle can not enter, so it is impossible to wind the wire, try to use manual.

3. The slot is greater than 2mm, normal 2.5mm or so, this time the needle into the easier, winding is easier.

As can be seen, the stator slot distance is very critical, of course, also with the automatic brushless motor winding machine equipment configuration and precision, in the design of the stator, must take into account the feasibility of the equipment, or the later change to change to waste time and money.
