We know that relative speed is responsible to induce voltage. If rotor and the rotating field (stator) speed is same, no voltage will induced because relative speed will be zero. For IM relative speed is not zero and it does not move with sync. speed, and so it is called asynchronous motor.

∙ 9y agoBecause there is no electrical connection between its stator and its rotor. Voltages and, therefore, circulating currents are induced into the rotor by a rotating magnetic flux set up in the air gap by the stator windings.

What is an Induction Machine?
An asynchronous alternating-current machine, such as an induction motor or induction generator, in which the windings of two electric circuits rotate with respect to each other and power is transferred from one circuit to the other by electromagnetic induction.Reference: Wiki Answers

How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
Why dc motor is not named as conduction motor?
In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a Conduction motor. However, in ac motors, the rotor does not receive any electric power by conduction but by induction in exactly the same way as the secondary of a two winding transformer receives its power from the primary. That is why such motors are called as Induction motors. An induction motor can be treated as a rotating transformer i.e., one in which primary winding is stationary but secondary is free to rotate.
Theory for brake test on three phase induction motor?
why three phase induction motor is delta connected
What is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
What is an inducting motor?
induction motor has two control system one is stator control another rotor control And it comes under the category of asynchronous motors. The term induction is because the rotor of an a.c motor does not receive the electric power through conduction but by induction same as the secondary of the transformer receives the power from primary. And so an induction motor can also be called as a rotating transformer i.e. one in which primary is stationary and secondary is free to rotate.

What is an asynchronous linear-induction weapons?
along the lines of a railgun or coilgun
Why induction motor is called asynchronous motor?
as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torque. so since the rotor runs with a speed other than the synchronous speed of rotating magnetic field produced by stator current so it is called as asynchronous motor.. asynchronous -means not moving with synchronous speed --------------------mrityunjay (kiit university . b.tech 2nd year student)
Self starting single phase induction motors are also called?
Split Phase Induction Motor.
Does induction motor works on Electromagnetic induction?

What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
Why the DC motor is call as synchronous motor?
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
What is a decripition of Nikola Tesla induction electric motor?
