The word coil stands for a series of loops and the process of making an electromagnetic coil is termed as coil winding. Such electromagnetic coils are used in components like relays, resistors, chokes, inductors, solenoids, transformers, rotor and stator in electric motors or generators. Many types of equipment need coil winding to be done in different designs shapes and patterns. Such machines range from hand operated winding machines to automatic machines which are generally very expensive. There exists a huge range of machinery including gear, hydraulic, bench-top coil winders and multi-spindle stand-alone winder machines which provide the necessary winding over the component or device.
There are some machines which have a real-time multi-tasking control. They can support many axis for winding, tape-wrapping, changing wire sizes and a controlled vertical and horizontal wire terminating. Today the such machines are fully automated and meet all the winding and finishing requirements. This industry has grown over the last 40 years. Today there are many companies around the globe which offer such solutions having high levels of endurance, power and performance. Any winding machine can be adjudged by its ruggedness, reliability and an ease of maintenance.
The major problem that arises is different precision wound components. There are different techniques and methods which provide a very reliable and accurate coil winding on components like solenoids, transformers, custom coils and high precision wound ones. Most of the application exists in the field of electromagnetic devices and does require some skilled technicians who follow a well made plan and stringent guidelines. Other than winding machines the wire flatteners, dereelers/ tensioners, trickle impregnation and expandable mandrels machines are also associated with these electromagnetic device industries.
There are companies manufacturing medium to large capacity coil winding machines to meet their customer’s specific requirements. They make machines for making capacitors, choke coils, degauss coils, flat strip coils, lattice coils, perfect layer coils, large transformer coils, relay coils, resistor coils, rotor coils, spiral coils, stator coils, transformer coils, TV coils and many other types. The industries make these winding machines which are very well equipped to handle a variety of coil and wire winding applications.
