  2. Reluctance motor - Wikipedia

    en.wikipedia.org/wiki/Reluctance_motor

    The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .

  4. Stirling engine - Wikipedia

    en.wikipedia.org/wiki/Stirling_engine

    The Stirling engine uses the temperature difference between its hot end and cold end to establish a cycle of a fixed mass of gas, heated and expanded, and cooled and compressed, thus converting thermal energy into mechanical energy. The greater the temperature difference between the hot and cold sources, the greater the thermal efficiency.

  6. 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 ]

  7. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    A capacitor start motor is a split-phase induction motor with a starting motor capacitor inserted in series with the startup winding, creating an LC circuit which produces a greater phase shift (and so, a much greater starting torque) than both split-phase and shaded pole motors. This motor has a centrifugal switch which disconnects the ...

    A recliner Recliner aboard a business jet. A recliner is an armchair or sofa that reclines when the occupant lowers the chair's back and raises its front. [1] [2] It has a backrest that can be tilted back, and often a footrest that may be extended by means of a lever on the side of the chair, or may extend automatically when the back is reclined.
