    en.wikipedia.org/wiki/Robinson_R22

    The first version was produced as the R22, followed by the R22 HP, R22 Alpha, R22 Beta, and R22 Beta II. Superficially, the aircraft appear similar. The R22 HP was fitted with a 160 bhp Lycoming O-320-B2C engine, an increase of 10 bhp (7.5 kW) over the original R22. The steel-tube frame on the R22 Alpha was modified by extending the aft landing ...

  4. Power band - Wikipedia

    en.wikipedia.org/wiki/Power_band

    While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range [1] (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output.

  5. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field , and an inside rotor attached to the output shaft producing a second rotating magnetic field.

  9. Fractional-horsepower motor - Wikipedia

    en.wikipedia.org/wiki/Fractional-horsepower_motor

    A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than one horsepower (745.7 W) (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred to as a 'micro-motor'.
