<p class="p__1">An induction motor or asynchronous motor is an AC electrical motor in which the electric present in the rotor needed to produce torque is acquired by electro-magnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. squirrel-cage induction motors are extensively utilized as industrial drives since they are self-starting, reputable and affordable.</p>
<br>
<p class="p__2">Although traditionally used in fixed-speed service, induction motors are progressively being used with variable-frequency drives (VFD) in variable-speed service. VFDs use specifically essential energy cost savings chances for existing and potential induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel-cage induction motors are extremely extensively used in both fixed-speed and variable-frequency drive applications.</p>

<p class="p__3">By manually turning switches on and off, Walter Baily demonstrated this in 1879, successfully the first primitive induction motor. The first commutator-totally free single-phase A/C induction motor was created by Hungarian engineer Ott Blthy; he used the single-phase motor to move his creation, the electrical power meter. The very first AC commutator-free three-phase induction motors were individually invented by Galileo Ferraris and Nikola Tesla, a working motor design having been demonstrated by the former in 1885 and by the latter in 1887.</p>
<br>
<p class="p__4">In April 1888, the Royal Academy of Science of Turin published Ferraris's research on his Air Conditioner polyphase motor detailing the foundations of motor operation. In May 1888 Tesla provided the technical paper A New System for Alternating Current Motors and Transformers to the (AIEE) explaining three, four-stator-pole motor types: one having a four-pole rotor forming a non-self-starting hesitation motor, another with a wound rotor forming a self-starting induction motor, and the 3rd a true simultaneous motor with a separately excited DC supply to the rotor winding.</p>
