Eludium space modulator wanted, for an earth shattering BOOM!

.

Need a circuit diagram and a component list to build a Pulse Width Modulation speed control for a 48 volt six horse power DC motor. Come on folks... you are the brightest people I know....... Help?

(Why you ask? Because I need one..... details will follow later. It's all perfectly legal, trust me!)

og said...: Why PWM? an AC motor with a freq drive will be torquier and cheaper to run, unless the DC motor in question cannot be easily replaced.

have you looked at ebay? Reliance Electric used to make awesome DC drives with a lot of very useful features.; September 30, 2010 at 11:11 AM
Carteach said...: Og, I have a 'go-cart' project I am working with some students on. It has a 48v 6hp DC motor direct fitted to a differential. It's what we have to work with. Any funds to build this monstrosity are coming from my pocket. I have to work with what I have.

Besides, no one else has one, and it's kewl.; September 30, 2010 at 1:19 PM

I have this philosophy.... All humans are faced with a choice.

They can become students of human nature, trying to recognize the good and bad within themselves... or they can choose to ignore human nature, and act simply on drives, desires, and instincts. The former is what sets mankind aside from animals, and the latter is to act as an animal.

Making the first choice is harder, more complicated, and creates a difficult path to follow... for it's the basis of knowing right from wrong. There are those who study human nature, and themselves, and actively try to better themselves and do what is right. There are others... people who study human nature, note the flaws inherent to the unthinking herd, and use them as a means to control.

There is no danger greater than the refusal to see, and to think. Doing so leaves one a pawn to anyone awake, aware, and driven to power over others.

Robert Heinlein

"Do not confuse "duty" with what other people expect of you; they are utterly different. Duty is a debt you owe to yourself to fulfill obligations you have assumed voluntarily. Paying that debt can entail anything from years of patient work to instant willingness to die. Difficult it may be, but the reward is self-respect.

But there is no reward at all for doing what other people expect of you, and to do so is not merely difficult, but impossible. It is easier to deal with a footpad than it is with the leech who wants "just a few minutes of your time, please — this won't take long." Time is your total capital, and the minutes of your life are painfully few. If you allow yourself to fall into the vice of agreeing to such requests, they quickly snowball to the point where these parasites will use up 100 percent of your time — and squawk for more!
So learn to say No — and to be rude about it when necessary.
Otherwise you will not have time to carry out your duty, or to do your own work, and certainly no time for love and happiness. The termites will nibble away your life and leave none of it for you.

(This rule does not mean that you must not do a favor for a friend, or even a stranger. But let the choice be yours. Don't do it because it is "expected" of you.)"

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
