Delta’s ASDA Series AC Servo System and Coil Winding Machine

[Introduction] 
There are many daily applications that use coils, such as the pickup head of a DVD player, power supplies,
electronic transformers, switching transformers and motors. In particular, applications for motors are various and many.
 The vehicle industry is a typical example, where just one luxury vehicle requires almost 150 motors. The
requirements for motors are also very high.
In general, a motor has a stator and a rotor.
The stator is a stationary element, and the rotor is a rotating element.
A stator comprises plural stacked silicon steel plates wrapped in several sets of tightly-wound copper wires called coils.
The coil’s winding is critical in the manufacturing process of stator construction and also very important for the quality of the motor.
There are many kinds of coil winding machines for the manufacturing of many types of stators.
For coil winding machine applications, Delta provides high-resolution servo systems to facilitate the high-speed and high-precision winding process.

[Functions] 
Typically, a coil winding machine includes at least one XYZ moveable table and one high-speed rotatable spindle axis.
With single-axis point to point motion commands, the XYZ moveable table moves the motor stator to the working position where copper wires are fastened, wound and cut.
 To complete the winding automatically, the XYZ moveable table fastens the head of the copper wire on fixed pins.
The spindle axis adopts Delta’s servo systems which carry a feeder, supply copper wires, and wrap the stacked silicon steel plates in several sets of tightly-wound copper wires.
After the winding is complete, Delta’s servo systems help the system to stop precisely at the working position and ensure the copper wires are coupled and not released.
With increased winding speed production capability is enhanced substantially.
