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 ...
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
The universal motor is modified in several ways to allow for proper AC supply operation. There is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in DC motors. [2] A universal motor's armature typically has far more coils and plates than a DC motor, and hence fewer windings per ...
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]

As another disappointing New York Jets season nears its end, quarterback Aaron Rodgers has some thinking to do. Rodgers and the Jets have had a tough season, going 4-10 and struggling on both ...
A shaded-pole motor is a motor, in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole to produce a weakly rotating magnetic field. [2] When single phase AC supply is applied to the stator winding, due to shading provided to the poles, a rotating magnetic field is generated.
