Electric light pods

PostPost by: john.p.clegg » Mon Aug 04, 2008 12:55 pm

Hi all
Am now officially on the sick,so thought I'd spend some time spannering ready for the EFI,where to mount the swirl pot and pump.....only place there's room is the nose (no jokes about my Jewish ancestry) so while in there I'm goimg to move/tidy things and prepare for the electric lift motors....at first glance the drive pivot on the pod seems to move 4" (is that correct?) and the arm of the motor is 2" in radius.....am I lucky or am I missing something....I know some of you out there have done this....
also the motor mounts seem to align with the inner shell....looks like a flat ali plate will glass/bolt flush?

Other things to do while in the nose.....full width radiator.

John :wink:


P.S. excellent day at Woodvale-wouldn't miss it for the world

Hi

Just fitted electric motors last week, just tidying up the wiring and adjusting the rods now.

What motor are you using?

I used Mazda MX5 motors but if you use them as they are the pods will only come up half way and back down again. I had to lengthen the rotors, if you use Toyota Supra motors they have longer rotors.

See pics attached, look at the end of the rotors in comparison to the mounting holes, if you need any help with extra pics let me know.

The measurement of the required length of the motor arm would be helpful :)

Jason/Steve

Being greedy I hava a pair of each (1 1/2" and 2" arms),do you have a shot of them fitted as the idea I have is a flat plate fitted flush to the "inner wing" with the motors in the "recess",the rotors fitting through the plate inwards....sorry for the description but a picture is worth a thousand words...

Rather than get or make different rotor arms, you can drill new holes in the pods, closer to or farther away from the pivot point as required. The procedure I used was something like this:

1. Determine the stroke of the motor (length of arm x 2).
2. Determine the stroke needed to move the pod at its current drive point. I fastened some string in the nose that intersected the drive location at full-open and full-closed, and marked those points.
3. Calculate the ratio between these two measurements. If the motor stroke is too long, you'll need to drill the new hole farther from the pivot; closer if too short.

I think - PLEASE CHECK BEFORE DRILLING! - that the required distance from the pivot is current distance * (motor-stroke / current-stroke).

You will need to drill the new holes, then align the shaft of the motor with the line drawn between the new hole in its open and closed position - use the string again.

I gave myself some wiggle room by using 1/4" nylon actuating rods, which can bend slightly under compression.

I just bolted an extra piece of plate onto the rotor to lengthen it.

Yes Meccano is my friend :lol:

Hi John

This is an easy one for me:

Yellow = Down
Red = Up
White/Red = Permanent live
Black = Earth
Green = You do not need this one

The red and yellow you can use as up or down its up to you, wire the black to the battery earth and the White/red to the live on a battery, then touch the yellow wire to the battery live and the motor will turn half a turn. Take the yellow off of the live and touch the red wire and the motor will turn the other half a turn.

I have tested these motors so many times I can do it in my sleep. :)

Jason/Sadlotus

Many thanks,am still struggling,have five wires,two go into the motor and permenantly turn it when 12v applied,the other three go into a circular switchbox,green common ,blue and yellow via diodes to contact plate,both with off segments 180 opposite....there seems to be another switch at the bottom of the motor drive but cannot figure out if/how it is wired???
I have tried wiring motor via the circular switchbox but the inertia allows it to pass the off segments???

Any help gratefully recieved

....Have just got it to work...in a fashion...live 12v to red/white,green to black/white,earth to yellow-half turn,earth to blue-half turn.......without any load it keeps on spinning.....with a light load seems to do the job???

John :wink:
Any suggestions?

I've have my Single toyota supra motor setup running now for a few years and it's has never failed I use a 2.2ohm ceramic wire wound resister to set my speed and a home made control box the does not need limit switches. you are best using a single motor and a s130 type balance bar in my opinion and one single pod spring to counter balance the pod weight and give it an strong pod up bias.
If anyone is a bit stuck just pm me and I will do my best to help

To all you chaps that have done this- "You have my admiration",I am now on day three and have mounted the motors,figured out the wiring (if the inbuild switch/discs wil take 1.5amps-not wired them yet)got an approx figure for the operating arms(M6 threaded rod) and am about to cut and weld the motor arms as they seem too long....

Job done.....well pleased....had a slight problem as the left hand pod would continually wink as the other raised and stayed there,some delicate setting of the rotor arm with a lump hammer to lengthed it and repositioning of the interrupt switch has seen the problem solved....still unable to post piccies (I.T.thickie) but used a small piece of ali plate with a hole in it as the mounting and all is well....driven from the lighting switch (second position) so no need for the vacuum switch...(any ideas?)

John :wink:

P.S. if you want piccies give me a email

I installed a hazard flasher switch in the unused location - description here.
