   Winding machine Winding nozzle in winding position Winding nozzle in position for termination Determination of the necessary space between teeth depending on the wire gauge (Source: Aumann GmbH) To efficiently wind narrow slots of electronically commutated multipole three-phase motors, the teeth are coated with insulation and directly wound ...

4. 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

5. Growler (electrical device) - Wikipedia

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

   A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current. When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the ...

6. 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]

7. 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]

9. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   The coils of this winding are wound with fewer turns of smaller wire than the main winding, so it has a lower inductance and higher resistance. The position of the winding creates a small phase shift between the flux of the main winding and the flux of the starting winding, causing the rotor to rotate.
