DC Motor Characteristics-2/ Speed and Armature Current characteristics of DC Shunt and Series Motor
Просмотров 5 тыс.4 года назад
This concept reveals the response of torque and speed produced by the Motor during when the load changes are observed. There are three different characteristics of the Motor: 1. Ta vs Ia 2. N vs Ia 3. N vs T Having discussed first two in the previous online lectures, Let us see the third one in this session: Speed (N) vs Armature Torque (Ta) concerning DC Shunt and Series Motors.
Speed and Torque characteristics of DC Motor/ DC Motor Characteristics -3
Просмотров 26 тыс.4 года назад
DC Motor characteristics unleashes the entire operation of the Motor. Especially explores the behavior of the Motor under load. In other words this concept reveals the response of torque and speed produced by the Motor during when the load changes are observed. There are three different characteristics of the Motor: 1. Ta vs Ia 2. N vs Ia 3. N vs T Having discussed first two in the previo...
DC Motor governing/operating equations
Просмотров 1,5 тыс.4 года назад
DC Motor governing equations provide great scope to understand the behavior and characteristics of the Motor. Not only that, typical relationships between input and output parameters are observed to make the analysis easy between them. There are only three main equations of focus, 1. Back EMF 2. Speed 3. Torque Obtaining output parameters in terms of the input parameters is a typical aspect of ...

To reveal the behavior of the DC Motor it is very important to investigate the characteristics of DC Motors, there are three different aspects of it: 1. Ta vs Ia 2. N vs Ia 3. N vs Ta Let us see the first one in this lecture
3 Phase Voltage Source Inverter - 180 Degrees mode
Просмотров 31 тыс.6 лет назад
Inverter is a power electronic converter that converts DC to AC. This discussion focuses on three-phase voltage inverter in 180-degree mode, working principle with the help of waveforms with a clear idea of the switching sequence of the solid-state switches present in the Inverter.
DC Motor Significance of Back EMF
Просмотров 17 тыс.6 лет назад
Back EMF(counter EMF) is an important parameter to be considered for a DC Motor. Back EMF enables Motor to be self regulating Motor, which is a unique feature of DC Motor among-st other Motors.

Rotating Magnetic Field
Просмотров 18 тыс.6 лет назад
Rotating Magnetic Field in the 3 phase Induction Motor is self rotating by its virtue. Kindly consider a change in current direction through three phase winding. Cross(❌) indicates the current inwards i.e., away from you (in to the board) and Dot(.) indicates the current outwards i.e., directed towards you. Regrets for having quoted reversely.
3 phase Induction Motor working principle

Three phase Induction motor operating principle differs from the DC motor in the aspect of current availability in the rotor winding.
Electromotive Force(EMF)
Просмотров 2 тыс.6 лет назад
In the year 1831 Micheal Faraday has given laws of Electromagnetic Induction, based on which different methods of EMF are proposed.
DC Motor working principle
Просмотров 9 тыс.6 лет назад
DC Motor Principle: When ever a current carrying conductor is placed in the presence of magnetic field, a force is exerted on the conductor, hence the Motor rotates.

Is it possible to do a demonstration? This is very helpful and understanding , thank you
Thanks for making a video with clear explanation and on point relevant discussion.
Thank you.
You are really a great teacher.
Thank you dear, expect more videos in the near future
Please more videos sir thank you
Yes, planning now.
Does the current through the voltmeter not become extremely high and voltage drop over the currentmetering tool become extremely high aswell??
Excellent
Thank you sir 🙌🙌
Amazing❤
What a splendid presentation❤
Glad you liked it
Good morning, please can you explain prony brake torque please, I confuse t(w.l) and (w+w)×l please Explain
Plz keep uploading your videos
Thank for great lecture💯,great explaination💯❤👏
You are very welcome
Is ct a step or step down tranzformerer?
CT is used to step down the current by increasing number of turns of the winding. So you can understand accordingly.
Wonderful explanation sir, make more videos on different concerts of EEE
Concepts
Sure I will
Great video, please keep up the good work. Thank you.
Thanks for watching!
Excellent. Ur work was help full for my paper passing
Such a great explanation!! Many thanks to you sir.
Helpful
Excellent Teaching.
I'm proud of you because you're my teacher.❤❤❤
Thank you dear.
yo this nigga got swag on screen, man very good presenter, charming and intelligent,. My man you got a gift. and thank you for blessing us with that knowledge
Nice explaination Sir
Skilld is must be nice
Can I power shunt motor with car battery?
As long as the ratings of the Motor and battery are matched, there shouldn't be any problem.
Can I use floaded lead acid battery to power a DC series motor of 16v, 3.3amp ,0.5hp
Subjected to the ratings of Motor and battery.
Your teaching style is great, thank you sir 😊 , keep doing this 👍
excellent !!
Wow.Its like you were born to share this complex working method in simple way.Thanks a lot
Thank you, dear.
Sir ji Maja aa gya padh kar....
When the synchronous motor runs at synchronous speed the voltage induced in the damper winding is????? maximum Minimum 0 ????

Aaa aaa aaa aaa aaaa aaa aaa
Thank you sir, doubt solved.
This channel is underrated. A lot of thank you(s).
What do you meant by underrated?? Your reply can help me to change my approaches. Tq
@@learnwithus-electricalengi7390 I meant that this channel should be popular. Your method of teaching and interacting is of another level. It felt like I am sitting in a class and attending the class. By the way, today I had my Electrical Exam and this video helped me today. I got a question for 8 marks to explain the characteristics and I wrote everything I learnt from this video. Thanks a lot.
@@c-06kumarmayankraj81 Appreciations for the good words, Dear and Congratulations for you could write your test well.
