  4. Electric motor - Wikipedia

    en.wikipedia.org/wiki/Electric_motor

    A piezoelectric motor or piezo motor is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied. Piezoelectric motors make use of the converse piezoelectric effect whereby the material produces acoustic or ultrasonic vibrations to produce linear or rotary motion. [ 85 ]

  5. Homopolar motor - Wikipedia

    en.wikipedia.org/wiki/Homopolar_motor

    Electromagnetic rotation experiment of Faraday, ca. 1821 [2] Working principle of a homopolar motor: due to movement of negative charges from center towards rim of the disk, a Lorentz force F L is created which brings the entire disk into rotation. The homopolar motor was the first electrical motor to be built.

  8. 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. The rotor magnetic field ...

  9. Linear motor - Wikipedia

    en.wikipedia.org/wiki/Linear_motor

    A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
