How to make 220V 4000W DC Motor Speed Controller ( RPM Control )

Contact number please

Why didn't you drive the big treadmill motor faster?

what makes the noise of electricity flowing at 50hz is the dimmer itself?

No like with photo mfk

this video gave me cancer

Also using a rectifier bumps up the voltage of the A/C converted to DC. So if you have 120v ac you will get roughly 160V DC

Thats a crusty method. You should at least have a capacitor on the DC side to clean up the energy signal.

Great proyect

Hello! my name is Florin and I am writing to you from Romania, I also have a 180v engine similar to yours and I don't know how to start it because it only works on 180 volts, can you explain to me what parts to buy to be able to start it in function? Thank you in advance!

i already done. something like that but motor has so many vibration at treadmill. Hot diode. Cable. High ampere.

your load

You use Dimmer plus diode/rectifier,What's diode kode...thanks for your answer ....

Thanks brother. I got an idea.

This 180vdc motor will work on 220v DC ???

You drilled a slanted hole

The motor speed controller are ac to ac or ac to dc

Ser The motor speed controller are ac to ac or ac to dc

Sir where to buy this product

Nobody dont use this system.if can you ask to an electrician.he will tell you dangers and negative directions

Thankyou bro its working

Itu motor bekas apa lurrr???

Hey where did that motor come from what appliance

Why did you lied thumbnail circuit ? I dun see tht circuit in ur video. So why put tht on thubnail and cheat for money ?? Cheated money is haram !

sir i need this speed controller for my treadmill how can i get

Kid, why are you lying to my control system? It ruined the asshole.

Can you build one for say 50kW?

Can we use it on ac two phase 5hp motor

Dimmer speed dc or ac?
Thanks 🙏

is this source AC or DC?

Hola estoy usando el mismo regulador del vídeo, el mismo puente rectificador pero no logro obtener los 170v que necesito para mí motor. Que podría ser? Gracias

Can you use this application for DC power? 🤔

Why are you using an SCR controller to run a DC motor?
1. Inefficient because part of the sinewave is clipped in order to reduce the output;
2. Reduced sinewave means less power output at lower speeds;
3. SCR Controller should not be used as a DC motor speed control if you want power at lower speeds; and
4. Better to use a PWM DC controller to maximize efficiency and power output at any speed.

Why are all treadmill motors DC, can't they be replaced by AC..?

How to make or how to buy? Ready made motor speed controller 😂😂😂

How to buy

Kindly tell me .
Where can I get a motor controller device?

From where do we purchased it regulater

thanks a lot mr. electron, now i fixed and able to use my threadmill in a very affordable price, i applied your tutorial in this video. keep safe..

DISLIKE

Please I need your help Mr Electron, my question is can this work with 12V 81A 1.0HP DC motor? Please I need your urgent reply thank you

Ham ko chahiye

Hi brother can u advice me how to reduce the RPM on 24DC motor with 4 A I fixed this motor to gate but the speed of closing and opening to fast. Please help me on this

It's not a controller, it's just a power regulator. You can buy one at any electrical appliance store in your city. Such regulators are used to adjust (reduce) the power of the fireplace, soldering iron and other heating device. Exactly these are in electric drills. This is a primitive circuit, it just cuts a sine wave from the network. Those. the speed is reduced simply due to a decrease in the current on the collector motor. When a load is applied to the engine, the speed will drop, this regulator controls absolutely nothing.
A real controller of a collector motor has a RPM sensor, which is installed near the rotor shaft and, under load, maintains a constant RPM regardless of the load and the engine always runs at its full power. The shaft must have a magnet or a light reflector, depending on the type of sensor. These are expensive electronics with a specialized chip and sensor. Such controllers are sold too, chips are also sold separately.
For asynchronous motors, another method is used - a frequency inverter, because its RPM depends on the network frequency (50/60 Hz). This inverter supplies different frequencies to the induction motor - from a few hertz to hundreds of hertz. Thus, the RPM is not controlled, but the engine delivers its full power at any RPM. Frequency inverters are also sold.

hey boss!! Can you make a video with a bigger electric motor from an treadmill? Like 4-5 hp?

Hi bro
Can I buy this controller from you?

Over load if max speed potensio on starting. This not reverensi for your make
