2. Induction motor - Wikipedia

   en.wikipedia.org/wiki/Induction_motor

   There are three basic types of small induction motors: split-phase single-phase, shaded-pole single-phase, and polyphase. In two-pole single-phase motors, the torque goes to zero at 100% slip (zero speed), so these require alterations to the stator such as shaded-poles to provide starting torque. A single phase induction motor requires separate ...

3. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ[1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or ...

4. Synchronous motor - Wikipedia

   en.wikipedia.org/wiki/Synchronous_motor

   Synchronous motor. Miniature synchronous motor used in analog clocks. The rotor is made of permanent magnet. Small synchronous motor with integral stepdown gear from a microwave oven. A synchronous electric motor is an AC electric motor in which, at steady state, [1] the rotation of the shaft is synchronized with the frequency of the supply ...

5. Electric motor - Wikipedia

   en.wikipedia.org/wiki/Electric_motor

   The three-phase induction is now used for the vast majority of commercial applications. [51] [52] Mikhail Dolivo-Dobrovolsky claimed that Tesla's motor was not practical because of two-phase pulsations, which prompted him to persist in his three-phase work. [53] The General Electric Company began developing three-phase induction motors in 1891 ...

6. Linear induction motor - Wikipedia

   en.wikipedia.org/wiki/Linear_induction_motor

   A linear induction motor's primary typically consists of a flat magnetic core (generally laminated) with transverse slots that are often straight cut [6] with coils laid into the slots, with each phase giving an alternating polarity so that the different phases physically overlap. The secondary is frequently a sheet of aluminium, often with an ...

7. Squirrel-cage rotor - Wikipedia

   en.wikipedia.org/wiki/Squirrel-cage_rotor

   Squirrel-cage rotor. A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the ...
