When designing a brushless motor, it is necessary to evaluate the performance of many motor parameters and components, and the stator coil is one of the important components. Motor stator winding machine also has a lot of requirements but also contains a lot of parameters, such as stator outer diameter, stator inner diameter, stator stack thickness, several wires and winding, wire diameter, number of turns, how many slots, slot distance and so on. Why do motor coils use 10 strands, 20 strands, or even 30 strands of enameled wire when winding, and use a thicker strand instead of winding?
First, motor winding related
1, the larger the wire diameter, the more difficult the Auto Winding Machine For Ceiling Fan winding, whether it is the external winding machine or the internal winding machine, the wire diameter of the brushless motor has certain requirements, generally more than 1.0mm is not so good winding, many machines have to non-standard customization, custom winding machine relative to the general winding machine, will be much more expensive, of course, this refers to the size of the wire diameter problem, Other aspects of the design of non-standard not excluded. Therefore, for example, if you need to wind 2.0mm of wire diameter, if several strands of wire are wound together, the general machine can be used to solve the problem, and the effect is the same.
2, the problem of damage to the wire, the thicker the diameter of the wire when winding, it is to scratch the enameled wire skin, which is easy to causes damage to the wire.
Second, the motor itself is related
1, the current through the wire will have a skin effect, which can weaken the winding overcurrent ability, that is, multiple wires over current ability than a single wire is certainly strong, small volume over current ability.
2, the maintenance problem of the motor itself, the large wire diameter is generally used very little, many maintenance factories do not have a general model of enameled wire in stock, the use of multiple wires instead of a single wire, can also solve a lot of after-sales trouble.
The above is "motor stator winding machine single-strand winding and multi-strand winding what is the difference?" Want to know more about ring winding machines, automatic ring crochet machines, automatic fly fork winding machines, and other information, please pay more attention to me!
