How to wire a simple solenoid? :(
 
I essentially have this:

http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWNX%3AIT

EXTREMELY basic... very simple. But I'm 100% clueless at how to HOOK IT UP :o

I'm using this for my regenerative braking system, already have the blocking (one way) diode, so no problem there. The stock lever has a switch inside of it when you press on it, no problem there.

Just need to figure out how to go from here :(

One of the large terminals is for high power input, the other is high power output. One of the small terminals on the top is ground. The other small terminal is energized when you want to engage the solenoid. pretty simple

...Already lost =[

I understand how it works, but I don't get how to hook it up. Hah :-\

High power input... uhm o.o

So... on one of the terminals, I put the + from the motor, and the OTHER larger terminal, the + back to the battery (With the block diode inbetween)...

One of the top smaller terminals is the ground... from the MOTOR in this case (I assume?)... and what's the other small terminal to? :( (What do I connect it to o.O)

Have I got 3/4 of them right so far? :D

u got the first bit right
but the top two points are for the in and out of the switch
(i think)

devino246 06-13-2010 09:04 AM

The top terminals are energized to switch the power on. Im gonna draw up a diagram for you. Its really simple.

oscaryu1 06-13-2010 09:06 AM

Why thanx :DDD

I have an idea of what it is... the two larger terminals are essentially what you're trying to connect, the top two is where power is APPLIED to make that electromagnetic field... and you just run a switch inbetween it? o.o

This is how mine is hooked up.... one of the big terminals has a single wire to the starter motor..the other big terminal goes to the positive on the battery... then there is a wire from one of the small terminals that goes to the ground in my case it goes all the way back with the positive wire and goes to the negative terminal... and then there is a switch connected between the POSITIVE cable COMING IN and thats ground is hooked into the other small terminal

Yep. The only reason for a solenoid is so that you dont need such a big switch. Your still using 12 or 24V, but the amperage and wire size is much smaller. Wire a switch to the small positive terminal. Activating the switch will activate the solenoid. You should hear a click when it switches.

oscaryu1 06-13-2010 09:40 AM

Sweet! :P So in this case, I'm actually using the power the motor is generating itself to ACTIVATE the solenoid, and also "charge" the batteries :D

Interesting.

oscaryu1 06-14-2010 10:04 AM

Well it worked... :) However I don't think there's an active "load" on the motor to actually create enough amperage to MAKE it useful.. :(

:confused: Can you explain in detail what your doing. Pics would be cool too.

try running a belt from the axle to a alternator... that my get the power you are looking for.. get some kinda small car alternator and you should be good.

Meh... too bulky :-\

Maybe I'll just go for larger batteries and make it a 2WD scooter. P:

This is my first post and I hope it's going to be a helpful one...I'm an electrical engineer and I hope I can be of help to some of you guys.
Oscaryu1, the picture of the solenoid in the ebay link you posted looks exactly like the Cole Hersee made solenoid that I see almost every day in my line of work.

Here's the linke to their product catalog
http://www.colehersee.com/catalog_top/index.htm

Here's what the solenoid looks like inside...
http://www.colehersee.com/pdf/soleno...080%20type.gif

Terminals 2 and 3 refer to the coil of the terminal, which could be 12V or 24V. Polarity is only important if you plan on connecting a suppression diode (highly recommended). You must connect the positive to the cathode (side of the diode with a silver band around it). When terminals 2 and 3 are energized, contact (the upside-down T) is pulled up connecting terminals 1 and 4. I hope this clears it up for you.

This thread is over 6 months old. If Oscar hasnt already figured it out, Im sure hes given up. Welcome to the forums.

yoop

Lynx_Genisys 01-28-2011 08:21 PM

haha.. fyi, that solenoid is basicaly the same thing as a 4 prong relay.. hehe.. jsut handles more amperage.. :D

(I know i know, its dead.. just thought id through that in their.. if he was using it to supply the field exciter to an alt, then a realy woulda sufficed.. lol
