2. Induction motor - Wikipedia

   en.wikipedia.org/wiki/Induction_motor

   Induction motors are most commonly run on single-phase or three-phase power, but two-phase motors exist; in theory, induction motors can have any number of phases. Many single-phase motors having two windings can be viewed as two-phase motors, since a capacitor is used to generate a second power phase 90° from the single-phase supply and feeds ...

3. Rotating magnetic field - Wikipedia

   en.wikipedia.org/wiki/Rotating_magnetic_field

   The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.

4. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   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.

5. Induction regulator - Wikipedia

   en.wikipedia.org/wiki/Induction_regulator

   The three phase induction regulator can be regarded as a wound induction motor. The rotor is not allowed to turn freely and it can be mechanically shifted by means of a worm gear. The rest of the regulator's construction follows that of a wound rotor induction motor with a slotted three-phase stator and a wound three-phase rotor. Since the ...

6. Stator - Wikipedia

   en.wikipedia.org/wiki/Stator

   Stator winding of a generator at a hydroelectric power station. The stator of these devices may be either a permanent magnet or an electromagnet. An AC alternator produces power across multiple high-current power generation coils connected in parallel, eliminating the commutator. Stator of a 3-phase induction motor

7. Squirrel-cage rotor - Wikipedia

   en.wikipedia.org/wiki/Squirrel-cage_rotor

   In 1888, Nikola Tesla received a patent on a two-phase induction motor with a short-circuited copper rotor winding and a two-phase stator winding. Developments of this design became commercially important. In 1889, Mikhail Dolivo-Dobrovolsky developed a wound-rotor induction motor, and shortly afterwards a cage-type rotor winding. By the end of ...
