2. Electric motor - Wikipedia

   en.wikipedia.org/wiki/Electric_motor

   An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to ...

3. Piezoelectric motor - Wikipedia

   en.wikipedia.org/wiki/Piezoelectric_motor

   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. An electrical circuit makes acoustic or ultrasonic vibrations in the piezoelectric material, most often lead zirconate titanate and ...

   1828, Ányos Jedlik. Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [3] [5] He invented the commutator. In 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and ...

6. 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 ...

7. Permanent magnet motor - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet_motor

   A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology. The schematic shows a permanent magnet ...
