2. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   The shaded-pole motor is the original type of AC single-phase electric motor, dating back to at least as early as 1890. [1] 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]

3. Induction motor - Wikipedia

   en.wikipedia.org/wiki/Induction_motor

   A single phase induction motor requires separate starting circuitry to provide a rotating field to the motor. The normal running windings within such a single-phase motor can cause the rotor to turn in either direction, so the starting circuit determines the operating direction.

4. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   Single-phase motors do not have a unique rotating magnetic field like multi-phase motors. The field alternates (reverses polarity) between pole pairs and can be viewed as two fields rotating in opposite directions. They require a secondary magnetic field that causes the rotor to move in a specific direction.

5. Fleming's left-hand rule for motors - Wikipedia

   en.wikipedia.org/wiki/Fleming's_left-hand_rule...

   Fleming's left-hand rule. Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule for generators. [1] [2] [3] They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.

6. Repulsion motor - Wikipedia

   en.wikipedia.org/wiki/Repulsion_motor

   A repulsion motor is a type of electric motor which runs on alternating current (AC). It was formerly used as a traction motor for electric trains (e.g. SR Class CP and SR Class SL electric multiple units) but has been superseded by other types of motors. [citation needed] Repulsion motors are classified as single phase motors.

7. 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.
