The best explanation I have gotten on this. Thank you
thank you so much sir and the whole organization
Just what I was looking for. Great video!
Wonderful explanation!!! Ud. se toma el tiempo y las pausas para explicar, o mas bien permitir que la explicación suceda en quienes le oyen, eso requiere tambien una frecuencia de hablar y permitir que lo escuchado decante en el silencio. Su frecuencia es la adecuada!
very informative ,thank you
Glad it was helpful!
Thank you. Pole numbers and RPM, Refreshed my brain 😀
Glad it helped!
Does this also apply to VSD? So I have to apply the frequency according to the nameplate (50/60 Hz)
240V makes better sense as it requires less or half amperage to deliver the same wattage of a 120V North American Circuit, in the UK we have 3000Watt water kettles and makes my cuppa tea 2x faster. In USA/CA we can't find anything more than 1500watts because the mains cannot handle the amount of current. It is amperage that makes a wire go hot and burn, just try shorting a 12v battery with a gauge of wire designed for 120v! It will burn your fingers in an instant! I've installed UK plugs in my N American home; only issue now is both wires are hot like the outer wires of a centre tap transformer so I needed to install a DPST switch to make sure both are off as a temporary solution. Power bars assume LNE configuration not LLE, so even if it's off you can still get zapped between earth and the still connected Live. In long run will install an European consumer unit probably in a ring circuir topology following British Standard requirements using the Brown, Blue, Yellow&Green sleeves that need to be imported, after converting to 50hz and do proper earthing/bonding and an RCD so to have Live, Neutral and Earth just like in Europe @ 240/50Hz not a floating 240V Live, Live, Earth @ 60Hz. Safer, with fused plugs and RCDs, not he flimsy connectors that falls off so easily. They will be two separate systems starting from where power enters. A proper install 120/60 next to 240/50 with Earth and Neutral. Running a 3000Watt kettle over a transformer will 2x the amperage on the primary / 120v input side of the transformer; nice way to get a fire if the breaker doesnt trip first and especially when none of the American plus are fused; for thost that are unaware.
As voltage converters do not convert frequency; how would you run your US electric clock (accurately) on a UK power supply, please? Thank you.
Thank you.
You're welcome! Thanks for watching!
Very informative VDO. Now I am in the opposite situation and would like to send a small 230V 50Hz lathe with a speed controller to the Philippines (230V / 60Hz). What would I expect there. Would it work. Using your clock as an example, the rpm would change Laid at the top, but otherwise functional. Am I correct. Thank you
shouldn't if be possible to make a motor with 3 6 or 9 windings? because even though it's not divisible by 2, every time it goes through a rotation, it would be the 4th time that a coil is activated, so like, even though it's 3 coils it goes through 4 every 1.3 rotations.... so it's like the same thing?
Pls. Am having this challenge i have an 11kw, 50Hz, 380V motor its always hating up within 5mins its been powered and its running on 50Hz what would be the problem???
Now I ask... Why 50 cycles create overheat on a 60hz equipment if theoretically (on my mind) the more frequency, the more friction and heat produced?
Lower frequency higher the peak voltage is needed to maintain the average voltage (what is used to measure ac voltage)
how much can you speed a motor by a VFD before it saturates ? Is there a way to calculate that ?
The variables make it difficult to provide a simple answer. Characteristics that are used to calculate include Voltage, Torque, Frequency, Inductance, and Resistance, to name a few.
If you you take the clock to Europe it will 12:51 and nearly 43 seconds after 1 hour
