DIY AC Motor Speed Controller (Easy & Cheap)

Upgrade your electric tools with our AC Motor Speed Controller – the game-changer for optimal performance and safety! ⚡🔒

I'd appreciate any support in buying me coffee.

🔧 Product Highlights:
Electrical Specifications: This speed controller operates within an input voltage range of 110-120V, handling a maximum current of 15A (rated current: 9A). With a robust resistive load capacity of 4000W and an inductive load capacity of 1500W, it's a powerhouse for various applications.

💼 Convenient Design: The back clip ensures convenience, allowing you to secure it to your belt while working. The rotary knob provides precise voltage control, and the LED voltage display makes monitoring a breeze.

🚫 Overload Protection: Your safety is our priority. The controller features an automatic power cutoff when the current exceeds 15A, preventing damage to both your equipment and ensuring user safety. The flame-retardant casing adds an extra layer of protection.

🔌 Standard Socket: Equipped with a standard socket at the bottom, compatible with both Type A and Type B plugs commonly used in the United States.

🛠️ Versatile Usage: From powering fans, small motors, soldering irons to handling resistive loads like kettles and electric heaters, this controller is a versatile addition to your toolkit.

🔄 Product Demo:
Watch till the end as we put this motor speed controller to the test! See it in action on a fan and a grinder, demonstrating its precision and efficiency in controlling speed.

Enhance your work environment, improve tool performance, and ensure safety with the AC Motor Speed Controller. 🌐 Grab yours now and take control of your electric tools like never before! #MotorController #PowerTools #DIYProjects #ElectricianEssentials #amazonfinds ⚙️✨

How many motors have ya burned up so far? All single phase AC motors require 50-60hz at their listed voltage rating... this module acts as a variable driver but cuts down the voltage for single phase motors... which is a NO NO. Your motors will only last so long before they burn up.. dont use these!

Been looking at these over here in the UK for my pond pump and air pump thank you 👌

Great review. I like how you can adjust the speed of various rotating appliances and tools. How long is the power cord?

[CharlesGwinn-eppb]

I think best use is for fans and lights because as voltage reduces, torque reduces much more.So power tools at severely reduced torque wont drill, or cut or grind nearly as effectively whereas as fan cutting thru air wont have the same relative load.

I’m using it as a soft start for my miter saw on my inverter in my work trailer.

If you put two of those inline (plug one into another) will it slow down my 8" vortex inline van even more. All the way down is not low enough.

Great review. Now I jus gotta dig one up...

Where do i get one? Want to polish knife handles and sheaths.

[coolbeans]

Do they have any with a higher amperage output?

Question, I have a treadmill 120V and want to slow it down. Would you recommend? Or is this bad for the treadmill?

[CharlesGwinn-eppb]

If you need to maintain useable torque(ie power tools) I think only solution is a VFD(variable frequency drive)...very cost prohibitive.

Can i use it to control the speed of my 0.5hp water pump?

They don't work on power tools. You completely loose torque.
