The differences are quite bold- (1) The Back emf for a BLDC motor is alternating in nature but not sinusoidal. Whereas, for a PMSM it's purely sinusoidal. (2) For a BLDC motor, the inverter needs to be operated using a PWM. But, for a PMSM, it should be a SPWM. (3) You'll experience a ripple torque in a BLDC Motor. But, torque is relatively smooth is PMSM. (4) BLDC motors are not feasible for high precision performances. But, one can use PMSM for that purpose. Hope that clears your doubt!
As the name suggests, the Syncronous motors are operate in synchronous speed. Whereas the induction motors are asynchronous motors. The speed of induction motors are slightly smaller than that of the sy. motors. The difference in speed is called a 'Slip'.
Thank you so much for showing how a synchronous motor works. Wayy better than a robot reading text at me like the other videos. We appreciate what youre doing
Thank you sir from the deep of my heart. From the topic synchronous motor one question was coming in my exam. I felt it would not affect if I leave that question. Still before the exam I thought to get basic knowledge about synchronous motor. So I watched your video. And I was extremely happy because I was able to attempt that 14 marks question. Thank you sir. Great support. Keep making educational videos..
I have a doubt..... Because of the three phase supply given in the stator, a rotating magnetic field occurs.The rotor is given DC supply so thus it creates stationary magnetic field around it. Theoretically The stationary magnetic field produced by the rotor should catch up with the rotating magnetic field of the stator thus because of magnetic locking the rotor spins(mechanical energy as output).......but the rotor should have some weight..... right? Is it possible for the rotor to catch up with the rotating magnetic field of the stator because obviously the stator field will be faster than a mechanical object. So the rotating magnetic field "might" complete multiple rotations even before the rotor catch up to it...so the rotor should be Oscillating instead of rotating right....??confusing :|
Yes! In this case, the rotor won't be able to start it's rotation, maybe it will just vibrate. That's why the squirrel cage is used. Listen to the explanation once anain, and you'll find your answer!
Yes. That's why the squirrel cage is placed over the rotor as a starting mechanism so that the rotor speed can catch up with the synchronous speed. Once, the speed of the rotor rises, the excitation is applied to the rotor to achieve the magnetic locking required for the synchronous speed.
How about controlling its direction.. I mean ..when it will change the direction of rotation? I read in Wiki.. it says until outside force is more greater than its torque.., it will change its direction or oppose the direction before.. once u go clockwise, if u stop it it will go now counteclockwise.
In order to reverse the direction of a PMSM, you need to generate a level shifted sinusoidal i.e. (v_dc/2)+Acos(ωt). In this case, there will be no current due to DC component (as it's a balanced circuit), but there will be current only due to Acos(ωt). And, as you know, this component can be -ve, so you'll be able to rotate the machine counter-clk wise. Hope this clears your doubt!
You guys really do great things. Your every video is great and the animation is just mind blowing. Please never stop, esle you'll made my study really tough.
Nor really! There's a very complex control structure behind the motor! There are many sensors, controllers, methodology, feedback control system and so on!

Synchronous motor is a doubly excited machine i.e two electrical inputs are provided to it. It’s stator winding which consists of a 3 phase winding is provided with 3 phase supply and rotor is provided with DC supply. The 3 phase stator winding carrying 3 phase currents produces 3 phase rotating magnetic flux. The rotor carrying DC supply also produces a constant flux. Considering the frequency to be 50 Hz, we can see that the 3 phase rotating flux rotates about 3000 revolution in 1 min or 50 revolutions in 1 sec. At a particular instant rotor and stator poles might be of same polarity (N-N or S-S) causing repulsive force on rotor and the very next second it will be N-S causing attractive force. But due to inertia of the rotor, it is unable to rotate in any direction due to attractive or repulsive force and remain in standstill condition. Hence it is not self starting....BUT WHY SQUIRREL CAGE SHAPED ROTOR IS USED?
+AJITH THOMAS I believe the squirrel cage bars are affected by the rotating magnetic field (RMF) such that it produces a force which begins to spin the rotor (see 2:46)
Was very much confused between this and induction motor and thought why can't this act as induction motor as both stators are excited by 3 phase supply and what was the need of excitation of rotor winding. Now I get it, great explanation .
Hi, thank you for all your great lessons. Would you clarify the difference between the damper winding of the synchronous machine and the squirrel cage of the of the induction motor?
Anyway the physics behind synchronous motor is explained beautifully with the help of animation...ur my science teacher😍😍 keep on making this kind of video

I have a question. Say this is 8 pole 60 Hz synchrnous motor. Now, in normal conditions, once it starts as an induction motor, rotor field coils are energised once at around 0.95 slip. What if, field coils are energised early, say at 0.48s? Thanks.

Motor Universal Axial-Coaxial The proposed invention is the engine, which bases its operation on the magnetic repulsion and the increase of the magnetic field by concentration of the lines of force. It is composed of rotating discs, which can rotate in the same direction, or in the opposite direction (counter-revolution). The discs contain permanent magnets (neodymium) that follow the rotating magnetic field, generated by the stator. It has a variable number of coils according to the revolutions or power that you wish to obtain. The rotation control is carried out by means of a magnetic field detector (hall) with electronic position control.

Please use basic words like "the" you dont sound fancier by eliminating them. It makes the video sound like a hack-job. If you are going to tackle a topic like this- at least exercise rhetoric that works along side. There is a tendency to leave out words to either sound more important or to save money... and it is not OK.
This video clearly portrayed the process for me. I was not able to visualize it. Great explanation and even better animation. Hope you bring out more such videos regarding electrical machines. Electrical machines seriously need people like you who make it easy to understand. Other sources of electrical are the same textbook handouts with narration that is hard to make sense.
In this video it was stated that a permanent magnet could be also used as the rotor. But the rotor was required to be de-energized first in order to self-start so how is this possible with a permanent magnet rotor?
While there are more than sufficient videos dealing with synchronous motors powered by three phase . there is not one single video describing just why and how a two pole magnet rotor ac motor powered by single phase works. Such motors may be found in washer drain pump application.
1:42 why the number 120? Here in europe we do have ns=60*f/p, where 60 stands for seconds in 1 minute, but cant find anywhere explanation for the 120 in your version.
Lol I thought that stator rotates similar to rotors... but the reality is that stator is stationary and which rotates is the magnetic field of it whereas the rotor it self rotates.. thanks for the video
Aw man, you're awesome! Just where have you been all the time, or what's your primary profession? Also how is the constant magnetic field controlled in permanent magnet motor? Or how's it turn on/off in electromagnet synchronous while the motor handles varying load?
It's not perfectly continuous, it has some ripple to it as the rotating coils pass between the stator coils where a little bit of miss alignment occurs.
How about controlling its direction.. I mean ..when it will chacounteclockwise.nge the direction of rotation?

In three phase induction motor as you've said Slip= Ns-Nrotor And Rotor speed try to catch up synchronous speed but that won't succeed If it will then motor will stop then how in synchronous motor slip is zero????
An induction motor produces torque only when slip isn't equal to zero. A synchronous motor produces rotor flux with electromagnets or permanent magnets so it always stays in synchronism.
Everytime #lesics @lesics i forget about Synchronous machine basic principles i tune into this video, within minutes I'm good to continue my engineering career😅🙏 thank you a lot
It might not be the best question to ask but I recently studied Ac motor(Induction motor) where I got to know continuous changing field induces Eddy current.what really confused me was as the magnetic field of stator kept changing it produced absolutely no effect on the magnetic field produced by the Eddy current as if it had induced permanent poles.The north and the South Pole of the induced Eddy current in rotor kept moving towards the magnetic field of the stator but could've simply reversed their field to counteract the change of field.why does that not happen? .I hope you can help me with it
Great video. A question here, from where does the mentioned direct current flow come from (video 03:01) to make the rotor rotate with synchronism? thank you

So a Synchronous Motor with motor looks like an BLDC but it is just powered by AC current?
The differences are quite bold-
(1) The Back emf for a BLDC motor is alternating in nature but not sinusoidal. Whereas, for a PMSM it's purely sinusoidal.
(2) For a BLDC motor, the inverter needs to be operated using a PWM. But, for a PMSM, it should be a SPWM.

It's not ok to call the stator coil a field coil in this case 0:33. The "field coil" is in the rotor. Be careful. The motor gets upset easily.

Indra Ida Bagus In that case you have to rely on some external prime movers to make the speed near to synchronous speed.

An induction motor produces torque only when slip isn't equal to zero. A synchronous motor produces rotor flux with electromagnets or permanent magnets so it always stays in synchronism.
Everytime #lesics @lesics i forget about Synchronous machine basic principles i tune into this video, within minutes I'm good to continue my engineering career😅🙏 thank you a lot

It might not be the best question to ask but I recently studied Ac motor(Induction motor) where I got to know continuous changing field induces Eddy current.what really confused me was as the magnetic field of stator kept changing it produced absolutely no effect on the magnetic field produced by the Eddy current as if it had induced permanent poles.The north and the South Pole of the induced Eddy current in rotor kept moving towards the magnetic field of the stator but could've simply reversed their field to counteract the change of field.why does that not happen?
.I hope you can help me with it
Please make this video in Hindi/Marathi .it is helpful for anyone.
Not all synchronized motors have squirrel cages though right?
Great video. A question here, from where does the mentioned direct current flow come from (video 03:01) to make the rotor rotate with synchronism? thank you
The synchronous motor is started via a DC current supply to the stator. It's explained at the start :)
Rotor is given a DC power supply and the stator is given a 3ø supply
