2. Winding machine - Wikipedia

   en.wikipedia.org/wiki/Winding_machine

   Winding machines are classified based on the materials they are winding, [2] [3] some major types are Coil winding machine; Film winding machine; Rope winding machine [4] Paper winding machine; Foil winding machine; Roll slitting machines; spool winding machine; cop winding machine; On the basis of working the winders are classified as follows ...

3. Coil winding technology - Wikipedia

   en.wikipedia.org/wiki/Coil_winding_technology

   In electrical engineering, coil winding is the manufacture of electromagnetic coils.Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones.

4. Growler (electrical device) - Wikipedia

   en.wikipedia.org/wiki/Growler_(electrical_device)

   A short in the coil creates a closed circuit that will act like the secondary coil of a transformer, with the growler acting like the primary coil. This will induce an alternating current in the shorted armature that will in turn cause an alternating magnetic field to encircle the shorted armature coil. A flat, broad, flexible piece of metal ...

5. Field coil - Wikipedia

   en.wikipedia.org/wiki/Field_coil

   A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which the field current flows. In a rotating machine, the field coils are wound on an iron magnetic core which

6. Electromagnetic coil - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_coil

   A coil with a core which is a straight bar or other non-loop shape is called an open-core coil. This has lower magnetic field and inductance than a closed core, but is often used to prevent magnetic saturation of the core. A coil without a ferromagnetic core is called an air-core coil. [14]

7. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   Small C-frame shaded-pole squirrel-cage motor. With the poles shown, the rotor will rotate in the clockwise direction. Shading coils (copper bars) within the magnetic circuit of the field coil. The shaded-pole motor is the original type of AC single-phase electric motor, dating back to at least as early as 1890. [1]

9. Voice coil - Wikipedia

   en.wikipedia.org/wiki/Voice_coil

   Thus a 100 mm diameter voice coil, with a 12 mm winding height has similar power handling to a 50 mm diameter voice coil with a 24 mm winding height. In 'underhung' voice coil designs (see below), the coil is shorter than the magnetic gap, a topology that provides consistent electromotive force over a limited range of motion, known as X max. If ...
