Hi, I have a project I have been working on, that has me out of my depth with regard to my knowledge, as I am a very basic electronic hobbies.
It comprises of a 24V D.C electric motor, 200W, 3,000 rpm, 13A. which has a pulley, a belt from this attaches to a pulley on a drive shaft, where a flywheel is situated, and on the other end, is a pulley, with another belt, that goes to a 230v AC alternator.
The motor is controlled by a Electromen EM-285 DC-Motor speed regulator 12 / 24V 20A. The regulator has three adjustable potentiometer, a Range trim, Current limit, and load compensation.
On the leaflet that came with the regulator for the installation, there is information that someone who works with electric motors, and speed controllers, which have potentiometer. Will know how to go about adjusting them to get the optima setting’s. But which has left me slightly baffled with my basic knowledge of electric motors, and electronics.
So I contacted the manufactures to see if they could help me, unfortunately they just repeated what was on the leaflet. But they did go off script a little, to quote from there email “There is no specific guidelines on setting the current-limit, I suggest experimenting until you find something that suits the application in question, start low and then increase”
So I experimented and found that if I sent the Range trim at a certain setting, and the current limit at another, the load compensation I left at zero.
With just the belt attached from the electric motor to the drive shaft, when I turned on the speed regulator, and increased the speed setting, the shaft started turning, I further increased the speed, and it picked up, and was moving very fast.
I then turn the speed down, and it slowly lost speed, until it was just turning over, and then I could slowly turn the speed up to a 100% again, and the flywheel was whizzing around.
Next I attached the belt from the pulley on the drive shaft to the one on the alternator. Turned...
