    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 ]

    Custom "U" Slot Insulation with sidewall step [1]. Slot insulation is the common name for shielding material used for the rotor inside a power generator.The slot insulation process for electric motors provides a barrier between the copper wirings and the steel lamination for all stator, armature and rotor products.

    Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.

  6. Brushed DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years ...

  7. Reciprocating electric motor - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_electric_motor

    A dual-coil motor would alternately energize the two coils. Where the motor is adapted to produce rotary motion, the return mechanism consists of a crankshaft and flywheel. This is an extremely simple motor, such that demonstration models may be easily constructed for teaching purposes. [4] As a practical motor it has several disadvantages.

  8. Electromechanics - Wikipedia

    en.wikipedia.org/wiki/Electromechanics

    The first electric motor was invented in 1822 by Michael Faraday. The motor was developed only a year after Hans Christian Ørsted discovered that the flow of electric current creates a proportional magnetic field. [5] This early motor was simply a wire partially submerged into a glass of mercury with a magnet at the bottom.

  9. Brushless DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushless_DC_electric_motor

    A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
