as it works on induced voltage on rotor according to faradays law of electromagnetic inductio ac motors called as induction motor
The AC motors works in the same principle as that of a Transformer. The AC supply is given to the stator and a rotating flux is set up in it. According to Faraday's Law, a voltage is induced in the rotor conductors as these conductors are in closed circuit, a current starts flowing through them as a result a magnetic flux is created around the conductors. Due to the interaction of the fluxes a torque is setup and the rotor rotates.
AC Induction Motor
how reversing an ac single phase induction motor to wark as induction generator
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
ac motor is nothing but induction motor.So check out for characteristics of induction motors.
The part of an AC induction motor that turns is called the rotor. The rotor is located inside the stator, which is the stationary part of the motor. When alternating current flows through the stator windings, it creates a rotating magnetic field that induces current in the rotor, causing it to spin and produce mechanical output.
Only Stator winding is similar in both the cases.
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.
single phase induction motor
Nikola Tesla invented the poly-phase induction motor in 1883.
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
