An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
H ave you seen those extraordinary "maglev" (magnetic levitation) trains that float on air instead of rolling on wheels? They're entirely electric but, instead of using ordinary electric motors that spin around, they use a kind of "unwrapped" motor called a linear motor that causes them to move at high speed in a straight line.
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the ...
Advantages & Disadvantages Induction Motor Instrumentation Tools
Induction Motor: Almost 70% of the machines used in industries now a days are 3 phase induction motors. It works on the principle of induction where electro-magnetic field (emf) is induced in to the rotor conductors when rotating magnetic field of stator cuts the stationary rotor conductors.
History and timeline of alternating current technology. 1835 - Hippolyte Pixii builds the first alternator.Pixii builds a device with a rotating magnet. He doesn't know how to make his creation useful since all the other experimenters of the time were building DC devices.
Synchronous Motor Working Principle - electrical4u.com
Electrical motor in general is an electro-mechanical device that converts energy from electrical domain to mechanical domain. Based on the type of input we have classified it into single phase and 3 phase motors.

Working or Operating Principle of DC Motor - electrical4u.com
A DC motor in simple words is a device that converts electrical energy (direct current system) into mechanical energy. It is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article.
