why is the music so loud????
😊
Super
Great film. But why the terrible back ground sound? It's hard to focus
why Triac based dimmer or fan controller or Voltage dimmer not able to controll speed of submersible pump ( 220 V , 2.5A single Phase ) when i tried it to decrease its Speed by Varing its Potentiometers to lower , Motor become unstable and consuming More current then Usual ????????
you just helped me with my senior year project thank you sir 🙂
Appreciated
Is there any power loss going through the VFD? Is there any power loss when changing ONLY the Hertz through a VFD?
If anyone can answer would be greatly appreciated!
I know they have a very good efficiency like 90% but I don't know what that means.

THANK YOU FOR THIS VIDEO.I HAVE QUESTION REGARDING TO FREQUENCY.I HAVE BOUGHT MOTOR FROM USA WITH FRQUENCY 60HZ AND I WANT TO USE IT IN OMAN .BUT THE PROBLEM IS WE HAVE IN OMAN 50HZ AND I AFRAID TO RUN THIS MOTOR.DO YOU HAVE ANY ADVICE TO LET ME RUN THE MOTOR IN OMAN WITH 50HZ???
it would have been much better if music was excluded.
hi , can i know what size i should select if my motor plates is removed but its working now with three phases location ( 220 v ) and by check with clamp meter i found each phase withdraw 5.5 A ON LOAD , the seller told me its about 2200 watt . can you help what size of kw i should but to run it in 220v single phase ? i need to know whats my motor capacity also ?
if my motor rotating very slow, wouldn't it get realy hot?
hello what vfd should i use for a 2.2 kw water pump? @t

Hello,
Can you kindly guide me that from any VFD which has output of 3-Phase 220V, can we handle speed control of 30V 6KW 3-Phase AC Motor with full torque?
INCREASING FREQUENCY will increase reactance, without increasing voltage will DECREASE magnetic SATURATION, and torque!
in the section "dc to ac inverter" why the motor doesn't change the rotation direction even when the voltage is in negative signe
The power socket is 2 phase, not 3 phase!
The main products are: high-performance vector inverter voltage: 110v, 220v, 380v, 460v, 575v, 660v six voltage levels; frequency: 0-650Hz adjustable; power: 0.4kw-630kw;
