Hi,

I've been looking around on the net about ways to rewire a smart drive to produce lower DC voltages. I must admit I don't think I will be able to do it. I really don't want to stuff it up. I'd rather leave the smart drive motor as it is and convert the power to DC and run it though a regulator and then a charge controller for the batteries, Is this possible?

If I want to get AC power off of it, which terminals Do I need to connect to etc? rewire or not?

Regards, Hamish...

Hi Hamish.

First up, its sounds like your new to this electical stuff, so be carefull. If you put your fingers on the terminals while spinning a F&P, you will get a VERY nasty shock, it could kill you.

That said, which F&P do you have? This page may help.

Also, what DC voltage do you want?

Hi There Glen,

First of all, thank you for taking the time to reply to my question and also, thanks for making this website. I found this website though Google, and even in my first few days of using it, It has taught me a heck of alot. Back to your question: Using the link you have posted, I believe I have the: "And this is the 60 series, note the messy winding, but this has no effect on performance. This stator has been de-cogged, note the rounded ends of the poles. Wire size approx 0.6mm diameter, 42 Poles." The one is the picture is the exact same as my one. What I basically want to is know how to connect two wires to my smart drive, one for positive and the other for negative and send it down the pole to be converted to 12 or 24volt DC etc down in my shed. I've seen people on youtube running light bulbs off F&P smart drives just by the turn of a hand. So that makes me believe that a smart drive can send AC power without being tampered with. I already knew that by reading on the internet but this just confirms that if you will. What my question is now, what connections on the F&P smart drive do I connect my two wires to, to get AC power. I have hopefully added a picture of the connections that are on the F&P smart drive, if you could point where positive and negative need to connect to on there, that would be great.

Regards, Hamish

Hi Glen,

sorry to make this hard, but theres not a 'positive' and 'negetive'.. With AC theres not really such a thing..

The F&P motor is 3phase. In very simplistic terms what you have there is three lengths of wire.. thats why you've got six terminals, one per end of the wire... to get power out of this, you need to use all three phases..

As you have it what you get off this is 3phase AC. Be careful those F&P's have considerable bite and can push out many hundreds of volts under no load situations.

I'll see if i can dig up a begineers guide link.

Every thing should be as simple as possible. Not simpler.

I was thinking that might be the case.
How do people on youtube light up light bulbs then?
Run it though a rectifier, is it?

Thanks for all the help,

LED's are diodes, so rectify [sort of] part of the cycle.

Hi,

I have been doing a good bit of research about my smart drive motor, and 3 phase and how it works. I have found 3 phase rectifier on ecoinnovation, which connects to the smart drive and takes it to DC, as you'd probably know. From there, it can go to a regulator, to take the power to 12 or 24volts, which ever I require. Quite happy with finding that out.

Another thing I managed to do was Decog the smart drive, by rounding the poles. It has made a massive difference to the smart drive. I am also in the process of replacing the 3 blade with 4 blades, which are also longer.

Regards,

Hamish
