Could you please do a video about fractional and integral slot windings and whats the difference with the distributed and concetrated windings. Thank you very much. 😊
First, thank you. The video is so helpfull. Now, I have a question. Could you tell me why we divide the magnets? I need to more details. As i understand, we divide to reduce losses in magnets,sheet and coil. But what are disadvantages?
wow .. very nice explained... I need your guidance.. i have been working and designed two permanent magnet (radial flux PM) machines but my target is go through an efficient control and robust design of PM machines. i have built some equations / formula/ i would like to share with you to look into and guide me.. pl
Tesla is claiming the motor torque is about 350-500NM depending on different models, so my question is the torque is after the gears or its just the torque of the motor?
Hey!!! I know it's been a while but there's something I've always wanted to know. Are there any advantages (BESIDES being known as the cheapest) to the use of old-style armatures DESPITE the ineficies caused by the friction of the mechanical brushes? What it was suspended with frictionless bearings? Couldn't it then be powered via an electrical induction device as now being utilized in the Axial flux, electrical motor design? Could such a design be mapped into a CAD system and "structurally" investigated one way or another to a definitive conclusion?
Yeah. I mean, does the ols universal motor/generator design have ANY inherent structural design attributes that other motor designs do not?@@Electric-Motor
@@panagiotisgeorgiou8011 Both motors do not need a starting aid if an inverter or power electronics is used. And an inverter is always used for high efficiency.
Please I need your help agently am trying to run three ac motor of 5.5hp on single phase source of electricity but if am trying to run all the three motor usually one of them will have a problem with the starting winding (burnt) what could be the problem
Because the area under a trapezoidal back EMF is larger than under a sinusoidal one. But this is a general statement and there are of course exceptions.
this is all the stuff i was reading in textbooks back when i was ten or so. all very basic and simple. i cant stand watching someone simply TALKING, and waving tehir hands around. wheres some practical demonstartions? like, hey, heres three coils of different gauges, same turns, same ampere turns... lets see which one heats up fastest... thats your ohmic losses. heres some iron, lets give it a taste of varying frequencies... theres your core loss, theres a BH loop, the hysteresis loss... or, iunno. heres a coil. on a core. with an adjustable gap. look at how we can vary the current and ohmic losses of the coil by varying the gap! see how it changes on teh scope in relation to the gap and the reluctance of the magnetic circuit? hey look, heres a welding transformer. see how the core moves, and alters the coupling, the current, when we have a fixed input supply and a fixed output load? its all related... now we have nice practical demonstrations of various principles, and we can walk away feeling we actually learnt something tangible, useful. oh. wait. we didnt use a scope. instead we had some guy stand there talking and waving his arms around. who wants practical when you can have theory and only just scratch the surface? if i didnt alredy know all this, it would be in one ear and out the other. as it is, the whole video was rather pointless. to me, this is sort of like watching an educational film targeted towards 8 year olds.
dont know what you expected for a 7 minute long video. i thought it was really good at covering the basics on losses, obviously it isnt going to be as in depth as a full research paper
What matters most is a perfect match of propeller and motor. So that motor and propeller work at their best possible efficiency point. But that's hard if you don't have the efficiency maps of the motor.
What type of motor would you recommend for agriculture use? Source of energy is solar ( so it is DC ), low speed needed only, robust ( heavier is better), cheap, doesn't have to be efficient... Thank you 🙏
Over all the video is nice, but I would suggest to consider stop moving your hands that much. They offer nothing extra to the explanation and it is rather annoying as it takes the eyes off the animation
