Why cam device is more popular in mutipole stator needle winding machine construction?
For BLDC stator needle winding machine, there are mainly two device construction, one is cam device and the other is servo motor device. what's the differece between them?
Cam device is critical in needle winding machine, stability of BLDC stator winding is most important for the automated winding process.In coil winding machine suppliers, some reputed Japan machinery manufacturers also use cam device.
Also four station needle winding seems have high output, four station BLDC stator winding machine usually use Servo motor device, due to the inertia of servo motor, four station winding machine is not suitable for winding wire size above 0.5mm,
While cam device stator needle winding machine have a wide range of application including thin wire, thick wire and stators with different kinds of bridge wire, terminal wires, winding way.
WIND-TSM series Stator BLDC winding machine have wide range of application for needle winding of brushless motor, stepping motor, compressor motor for refridgertors, air conditoner, power tool motor stator and so on.
In a whole, Cam device jave below advantages comparing to servo motor device of BLDC stator needle winding machine.
1. Cam device can achieve High winding speed up to 500RPM while other device can be up to over
100RPM, Even it have four stations, it is not faster than cam device
2 .Cam device move the needle and let the needle winding arraying the wires in stator slot when the
stator if fixed and don't move while other device nozzle move up and down when stator rotate
left and right, the nozzle might be damage during this process,
3.What ever 30°，60° or other angle the cam device can wind
4. Wide application range not only for small stator with light weight, but also big wire size big mutipole stators
