  2. Stator - Wikipedia

    en.wikipedia.org/wiki/Stator

    The stator is the stationary part of a rotary system, [1] found in electric generators, electric motors, sirens, mud motors, or biological rotors (such as bacterial flagella or ATP synthase). Energy flows through a stator to or from the rotating component of the system, the rotor .

  3. Armature (electrical) - Wikipedia

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

    Armature reaction is essential in amplidyne rotating amplifiers. Armature reaction drop is the effect of a magnetic field on the distribution of the flux under main poles of a generator. [5] Since an armature is wound with coils of wire, a magnetic field is set up in the armature whenever a current flows in the coils.

  4. Armature Controlled DC Motor - Wikipedia

    en.wikipedia.org/wiki/Armature_Controlled_DC_Motor

    Armature control is the most common control technique for DC motors. In order to implement this control, the stator flux must be kept constant. To achieve this, either the stator voltage is kept constant or the stator coils are replaced by a permanent magnet. In the latter case, the motor is said to be a permanent magnet DC motor and is driven ...

    root mean square The root mean square value of a waveform is the DC value that corresponds to equivalent heating value. rotary converter An electric machine that converts electric power between two forms, say, AC and DC or single-phase and three phase, or between two different frequencies of AC (the latter two can be performed by the same machine).

  6. Coil winding technology - Wikipedia

    en.wikipedia.org/wiki/Coil_winding_technology

    An electric motor or generator consists of a cylinderical rotating part called the rotor and a stationary part called the stator. For maximum efficiency, a gap between the rotor and stator is kept as small as possible, typically 1–2 mm. For most AC generators, the stator acts as the armature, and the rotor acts as the field magnet.

  7. Commutator (electric) - Wikipedia

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

    For a single armature winding, when the shaft has made one-half complete turn, the winding is now connected so that current flows through it in the opposite of the initial direction. In a motor, the armature current causes the fixed magnetic field to exert a rotational force, or a torque, on the winding to make it turn. In a generator, the ...

  8. Induction motor - Wikipedia

    en.wikipedia.org/wiki/Induction_motor

    The stator of an induction motor consists of poles carrying supply current to induce a magnetic field that penetrates the rotor. To optimize the distribution of the magnetic field, windings are distributed in slots around the stator, with the magnetic field having the same number of north and south poles.

  9. Armature - Wikipedia

    en.wikipedia.org/wiki/Armature

    Armature may refer to: Armature (computer animation) , kinematic chain used in computer animation to simulate the motions of virtual characters Armature (electrical) , one of the two principal electrical components of an electromechanical machine
