- #single_phase_induction_motor is not a self-starting motor and is a #capacitor_start_motor.
It is also called #capacitor_start_capacitor_run_motor, because capacitors are involved here for its operation.
Generally, a rotor of a motor begins to rotate, with the torque provided by its conductors, when cut by the #rotating_magnetic_field created by its field windings.
A #3_phase_induction_motor is capable of generating a rotating magnetic field on its own, since its three individual phases are moving with 120 degree angle difference with each phase.
For a #single_phase_motor, you have to initially supply an additional phase with a different phase angle, to create the rotating magnetic field for your rotor to start turning.
This additional phase is created with the help of #start_capacitor, for the single phase #induction_motor.
Behavior of the capacitor current with its phase angle, is explained here nicely with fine animation work.

I made this request six months ago, but no one has come forward to help this channel yet.🤔💔
I know, many have become patrons of entertainment channels mainly, but look forward to seeing at least some supporters who understand the value of an educational channel like this.
If you are not willing to visit a particular website for help, please contact me via email, sudarshan78@gmail.com
Your kind gesture will be most welcome..!❤❤❤
Thanks and Best regards.
Sudarshan,
Creator of Electro Academy Channel.
nice explanation
Thank you
finally, I catch it! thank you sir
Thank you
Hello! Please! Would someone explain me how can the voltage be synchronized with current on principal coil? The coil reactance doesn't make current be late compared to the voltage? Thanks...
Hi there...great video....but tell me...is this a 2 Pole or 4 Pole motor?...
A capacitor is a two terminal thing whose current through it is proportional to the rate of change of the voltage across it. That is , I= C* dv/dt. C just happens to be the “capacitance”. dv/dt is nothing more than the SLOPE of the voltage curve :)
Thanks for your comment
how can some ceiling fans revert its direction? What is the logic behind the magnetic fields and capacitors that allow this?
So I have a fountain and capacitor is blow, but wiring doesn't look correct as it has 3 connections from the capacitor but the drawing shows no live feed to the capacitor? Just a neutral in and 2 outputs. Is this correct? Single phase motor
What will happen if we use an inductor in place of a start capacitor in single phase induction motor? How could we get an inductor to work as a starter. I would love to see a video answering my question--I believe that this may aid my understanding of both capacitors and inductors.
The reason we don't do that in practice, is that capacitance is significantly cheaper than inductance, per unit of energy storage. So usually when a design is indifferent to a capacitor vs an inductor, the capacitor is preferred.
Another reason: the motor winding itself has inductance, which is especially evident at startup. You get a much more significant phase shift by pairing the motor winding with the opposite kind of reactive element, than you would get pairing it with the same kind of reactive element.
Super--thank you@@carultch
So basically, a capacitor start capacitor run motor runs as a two phase motor all the time, both when starting and when running.
Yes.
So it means the starting capacitor is bigger than the run capacitor right?
Yes
Why voice synthesis?
Sorry sir why starting capacitor is dead many times?
Capacitors also have a general lifetime.
However, If you connect a capacitor of acceptable brand with correct capacity, it will last longer.
A start capacitor always worn out due to on n off it endures when motor is starting n it's subjected to high current on start up of motor LRA.
Correct when you starting motor require high current
