2. 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.

3. Squirrel-cage rotor - Wikipedia

   en.wikipedia.org/wiki/Squirrel-cage_rotor

   Diagram of the squirrel-cage (showing only three laminations) The motor rotor shape is a cylinder mounted on a shaft. Internally it contains longitudinal conductive bars (usually made of aluminium or copper) set into grooves and connected at both ends by shorting rings forming a cage-like shape.

4. Rotor (electric) - Wikipedia

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

   An early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27. [2] Other pioneers in the field of electricity include Hippolyte Pixii who built an alternating current generator in 1832, and William Ritchie's construction of an electromagnetic generator with four rotor coils, a commutator and brushes, also in 1832.

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. 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.

7. Stator - Wikipedia

   en.wikipedia.org/wiki/Stator

   Rotor (lower left) and stator (upper right) of an electric motor Stator of a 3-phase AC-motor Stator of a brushless DC motor from computer cooler fan.. 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).

8. Armature Controlled DC Motor - Wikipedia

   en.wikipedia.org/wiki/Armature_Controlled_DC_Motor

   A motor is an actuator, converting electrical energy in to rotational mechanical energy. A motor requiring a DC power supply for operation is termed a DC motor . DC motors are widely used in control applications like robotics , tape drives , machines and many more.

9. DC motor - Wikipedia

   en.wikipedia.org/wiki/DC_motor

   Ball bearing motor – A ball bearing motor is an unusual electric motor that consists of two ball bearing-type bearings, with the inner races mounted on a common conductive shaft, and the outer races connected to a high current, low voltage power supply. An alternative construction fits the outer races inside a metal tube, while the inner ...
