speed control method of pedestal fan.
Hi.
I see in the stores a lot of pedestal fans that have lcd screen and remote control.
They have digital timer,4 speed and the possiblity of choose the behavior of the wind(besides the 4 speed):normal wind,natural wind,and night wind.
I know that the speed of the motor on most REGULAR fans is controled by resistor or capacitors.
From my description,what can be the speed control of those pedestal fans?
I read,also,that there are method that use triac or PWM to control the speed but i don't know if it is used on pedestal fans.
Thanks in advance.

Those pedestal fans use motors with multiple tapped windings. A PWM or variable speed drive will also work but is too expensive.

Hi PJmax.
I have ceiling fan and it changes its speed by changing a capacitor value(a small closed box,that has inside 2 capacitor).But it is not,of course,pedestal fan and i thought that there are also pedestal fan with that method.
So,can i understand from your answer that all the pedestal fans are using only the multiple tapped winding?
I especially refer to the new pedestal fans,which came with digital remote control and several type of wind flow possibilities(as i mention before).
Here is one example of one of the pedestal fan that i refer to.
★ authentic licensed Gree FD-4001B Remote Stand Fan fourth gear head wind flatback - HeroGate.com - A Professional Taobao Agent & More.
Is it also tapped winding speed control?
Are there any characteristics that can indicate what kind of speed control the fan uses?without openning it?

I have seen some expensive units use variable speed DC motors with a variable speed control.
If the remote control can variably control the fan speed then it is an electronic fan speed control.
If the remote has buttons on it... low, med, hi, etc. then it's probably a multitap setup.

I didn't,exactly, understand your answer.
What do you mean when you said" If the remote control can variably control the fan speed ..."you mean that the remote control have only one button for changing the speed of the motor,when each press on it,changed the motor speed?
And then you said"...then it is an electronic fan speed control."
What do you mean electronic fan speed control?
do you mean to the method that changes the frequency to the motor(inverters)?
and if the remote control have 4 button: one to each speed is it mean that it is probably multitap winding method?
For example:the pedestal fun that i mentioned before have 1 button on the fan which each press changing the speed,and another button that each press changing the behavior of the wind blow and the same idea is also on the remote control(one button for all speed+other button for changing wind pattern).
Is it mean that this fan is using pwm method,inverters?

If every push of a button changes the speed then I would assume that it is multitap motor.
I have seen controls that have an up and down fan speed rocker. Hold the up button and the fan speeds up. Hold the speed down button and the fan slows down. That would be a variable control.
Are you looking for something specific ?

I try to understand if the pedestal fans that come with remote control and have lcd screens are using inverters(ac drivers)to control the speed(by changing the frequency to the motor or they are the same as the regular one(mechanic ones),only that instead pressing manually(mechanicaly)on the button the electronic board changing the speed by moving the current flow to the other wind tap.(without using any triac,chopoing,pwm,etc).
You said now:
"If every push of a button changes the speed then I would assume that it is multitap motor..."
I assume you mean one button,that change all speeds.
before you said:
"If the remote has buttons on it... low, med, hi, etc. then it's probably a multitap setup."
I assume each button refer to one speed.one button to low,one button to medium,etc.
Maybe i lost something here and i am very confused.
Could you clarify this.

I have a remote for my fan here. It has four buttons on. Max, high, med, and low. You push the button for the speed you want.
Then there is another type of remote that just has one button. You push it once and it's max, a second push is high, a third push is medium and a fourth push is low.

Why..... curiosity ? Trying to build your own.
and multi tap motor without the ac driver(triac,pwm,choping...)seems to me more reliable.

I mean does the press on the remote control only changing the tap(the current to the stator) as the regular fan without another process that change frequency(ac drivers...)and etc.?

Hi,PJmax.
what happened?
Because i told you that i try to recognize the difference between them and not to build one ,you decided not to answer my questions.
I asked you several times the same question and you answer something else.why?
I asked you to clarify why you said that" If the remote has buttons on it... low, med, hi, etc. then it's probably a multitap setup."
and also"If every push of a button changes the speed then I would assume that it is multitap motor.."
so....???
Them both examples of multitap fans,while i asked you how to identify multi tap to ac driver ones.
Later i asked you again the same question,but you didn't answer it again.
I very apreciate the fact that you try to help,but i don't understand why there isn't any connection between my question and your answer.
Thanks

Here in the US (where most members live) it was a major holiday weekend (4 days for many people) with picnics, cookouts, fireworks and family gatherings. The site was much slower than a normal weekend, so don't hold lack of response as a personal thing.

Thank,again,for your help.
I am not angry about anyone,the opposite is true,you also helped me in the past and i appreciate any assistance.
By the way(slightly late)Happy 4th of july
