Hi Guys,
New user with not a lot of experience but what I would consider a reasonable bank of electrical knowledge. So I just need a hand to fill in the gaps.
Currently I have a Sunbeam popper which is 1150W. It has a 24VDC Fan Motor which from what I can research on it (nothing comes up when you search the model) is rated at 2amps. That is on a circuit board with some sort of rectifier to convert the AC-DC which is fine, however what I want to do is install two seperate controllers to slow down the speed of the roast - currently taking 3.5-4 minutes to roast 100g. Too fast in my opinion and the inners of the beans aren't consistent or roasted hardly at all.
So my plans are;
To use a Simmerstat or infinite switch to control the heating element which i've found here https://www.sparkydirect.com.au/p/94...ot-mp101-.html - thoughts on this??
and to run the 24VDC Motor on a seperate control using a full wave rectifier and a speed controller to suit but what I'm confused about is the DC Sinewave after being converted still resembles the drop off of an AC sine wave so I want to make it more of a consistent Direct current using a filter capacitor... but what size do I need and do you have any recommendations on how to set it up?? this is more of a project for me and something I'm enjoying learning about but having trouble with this..
So conclusion, How can I set up the DC fan using a full wave rectifier to incorporate a switch into the system to control the speed and if there are any other recommendations for a heating element switch too. I also found this too which I would like some advice on; https://www.amazon.co.uk/6V-90V-Puls.../dp/B00CWSO2IY would I be able to use this after the full wave rectifier and capacitor to control the fan speed??
See photos below of my components I am currently working with. Please ask if there is any more information you need to help!! Thank you!
