What is Coil Winding Machine?

In today’s world the technology plays major role in once life. And so as the technology is driven by one or the other form of the power, electrical power is also a major form of energy. In electrical power some of the components are used as a default and one of the component is coil. Mostly coil is used to generate magnetic field which is later used for various ways like stepping up the voltage, stepping down the voltage or only as a purely magnetic field. The coils will vary in size and quantity. So to produce the coils, machine is used which is termed as a coil winding machine. Basic function of this machine is to rotate the wire on any form of the core or bobbin or air.


Coil winding machine is having two major functional parts.

First is the rotating spindle and the second is the wire layering traverse. In short Spindle assembly and traverse mechanism are two major parts of winding machine while other parts may be part of the machine but its optional.

Spindle assembly can be rotated by various forces like hand or by motor. When the spindle is rotated by hand, it is generally called as hand winding machine or manual winding machine and when the motor is used to rotate the spindle, it is termed as motorized coil winding machine. The main function of the spindle is to rotate the bobbin or core on which wire is been wound which is called coiling of the wire. Now depending on the wire size and final coil weight alongwith the production required, either it can be hand rotated or with motor. Various HP motors are selected depending on the weight of the coil after winding. When the production required is too low then manually rotated spindle is generally preferred.

While when the coils are with high no. of turns or needs high production, motorized spindle is required. The spindle is coupled with the counter which displays no. of turns wound as the coil function on no. of turns. In the coils, there is requirement to include more turns in limited space of the bobbin and this need arise the requirement of the system which can spread the turns wound evenly or proper wound layer. The traverse mechanism performs this function of proper spreading of the turns. This traverse is either mechanically coupled with the rotation of the spindle motor or separate motor is used to move the traverse mechanism. When the spindle is rotating, the traverse unit is also moving synchronously as per the wire diameter so that the turns are been spread adjacent to each other. When one layer is completed the traverse unit will change its direction of moving so the second layer is been wound over the previous layer. The changing direction of the traverse unit can be either manually or automatic. The most important factor of the machine is the synchronization of the spindle with the traverse with respect to the wire diameter.

Acme Mechatronics, Inc. has expertise is designing various coil winding machines with highest degree of accuracy w.r.t. the synchronization between spindle and the traverse as this is been controlled by electronics circuit and not any mechanical part. The traverse unit reduces the speed or increases its speed w.r.t. the rotating speed of the spindle.
