  2. Coil winding technology - Wikipedia

    en.wikipedia.org/wiki/Coil_winding_technology

    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. The shape and dimensions of a winding are designed to fulfill ...

  3. Electric motor - Wikipedia

    en.wikipedia.org/wiki/Electric_motor

    An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric ...

  4. Hairpin technology - Wikipedia

    en.wikipedia.org/wiki/Hairpin_technology

    Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies, the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack. These copper bars, also known as hairpins ...

  5. Armature (electrical) - Wikipedia

    en.wikipedia.org/wiki/Armature_(electrical)

    Armature (electrical) A DC armature of a miniature motor (or generator) A partially-constructed DC armature, showing the (incomplete) windings. In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1] The armature windings conduct AC even on DC machines, due to the ...

  6. Induction motor - Wikipedia

    en.wikipedia.org/wiki/Induction_motor

    An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. [1] An induction motor therefore needs no electrical connections to the rotor.

  7. 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 a current flows. In a rotating machine, the field coils are wound on an iron magnetic core which guides the magnetic field lines.

  8. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.

  9. Commutator (electric) - Wikipedia

    en.wikipedia.org/wiki/Commutator_(electric)

    Parts: (A) commutator, (B) brush, (C) rotor windings, (D) stator (field) windings, (E) brush guides, (F) electrical connections. A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.
