3 Phase Voltage Source Inverter - 180 Degrees mode
Переглядів 32 тис.6 років тому
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
Переглядів 17 тис.6 років тому
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 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.

Speed Torque characteristics of 3 phase Induction Motor
State why synchronous motor is not self-starting. List the methods generally used to start synchronous motor.
A synchronous motor is not self-starting because it requires the rotor to match the synchronous speed of the stator field to generate torque. Starting methods: 1. Damper winding. 2. Auxiliary motor. 3. Induction start. 4. Variable Frequency Drive (VFD). 5. DC starter.
You saved my day 🙌
Is it possible to do a demonstration? This is very helpful and understanding , thank you
Sure I will try.
@@learnwithus-electricalengi7390 thanks, also is it possible to do a tacho aswell?
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??
A voltmeter connected in parallel to a high-voltage source but with a low internal resistance would draw significant current, potentially overheating and damaging the voltmeter. Similarly, an ammeter with significant internal resistance in series with a load would cause a noticeable voltage drop, leading to incorrect current measurements and disturbing the circuit. By using tools designed with the proper impedance characteristics for their intended measurement purpose, these issues are avoided
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
The Prony brake torque formulas differ based on the forces considered: 1. : Considers only the applied weight (). 2. : Includes both the arm's self-weight () and the applied weight (). Use the first when is negligible; use the second when significantly contributes to torque.
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

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 ????
0
@@muhammadomarwaqas4208 thank you 🙏🏻
When rotor rotates at the same speed as the rotating magnetic field of the stator, there is no relative motion between the rotating magnetic field and the rotor, including the damper windings. As a result, there is no induced voltage in the damper windings when the motor runs at synchronous speed. However, Damper windings are only used during the starting phase or when the motor operates below synchronous speed to produce a damping torque that helps the motor accelerate to synchronous speed. Once synchronous speed is reached, these windings do not carry any current, and no voltage is induced in them.
Super English, body language.
