What has an electronic experimental system to do with motors?

Going back to the history and the patents from the mid 1960s we have the motor for 9V DC – at the same time this block can generate up to 9V AC – all in one block 54x54mm (#8087) mit two separate magnet blocks (North pole / South pole = #8088 / #8089).

The first public appearance was 1968 on an exhibition as part of the Braun Set 111 (Experiments with the Motor) and a white cover:

On the next photo in the middle (my replica), to the left the motor block with a clear cover as we could order all the years (#8100600, since 1972; since 1977 part of the System 500 – Power Electronic – with still unknown contents) until today (#2603):

The motor block to the right is a “dummy” for this photo.  We only have the patent drawing:

and the two possibilities  to activate; the series motor (German: Reihen-Motor)

or as a shunt motor (German: Nebenschluss-Motor):

Mr. Birett told us that he had seen this motor around 1971 at Braun AG (M. Walter). But never again it was mentioned in literature or catalogues.

The next motor – with several transmissions – was taken from the hobby sector, used for the “cybernetics car” of Edzard Timmer and available since 1972 (#8170110) – with the metal construction kit parts (#8170120):

Even Mr. Guerth used this motor for proposals (motor control etc.):

The next motor was a very tiny one, running with very low voltage, and used for “Funktionsmodelle” from Mr. Birett (#8100511) including a suitable transmission top with relation 1:485 (#8100512) – since 1976 in catalogs. Later the solar experiments used a similar version (8100514). The actual order number is #2605.

Mr. Saucke developed another motor-like block to explain physical basics and magnetism. This version was available since 1976 (#8100505) until now (#2706):

Perhaps in the year 1995 (or earlier) a new type got part of the system: the stepper motor (#8100610, since 1996 in the catalogs, today: #2602). There two basic techniques: unipolar and bipolar.

The Lectron version is a unipolar type, 2 phases with 7.5° movement. The control can be done – in the simpilest way without electronic – via 4 switches (back-forward-left-right).

My version is a bipolar type and needs 4 double switches:

Before I forget – or: last but not least: the very first Lectron motor (still available) can generate AC. I you have a look into the 111 set you will see the 4 HV diodes. What are they good for?

Remembering another Lectron patent with a bridge rectifier – a combination of 4 silicon diodes with strange connection blocks:

I must say that the rectifier blocks of Mr. Guerth, Mr. Birett (and myself) are much better to handle:

Awaiting your motor application proposals – and thank you for reading until the end of this story…

Hi Günther,

I love this history!  Thank you so much for taking the time to write all this out.  Very interesting and lots of information that I never knew.  Excellent!

Hello all,

Thank you Guenther for your detailed info about the Lectron motors.

I have a question about one of these motors.

I’m interested in the motor 2603 but can’t find it at the Lectron website and in the “Baustein Katalog”. Is it possible that this motor isn’t available anymore ?

It would be great to use this motor with the digital blocks.

Many greetings

Last monday I sent an E-Mail to the Lectron GmbH asking for the motor 2603 as a separate order. Sadly I got no response until today.

If there is no chance / answer / solution – I may send you my motor. Perhaps Michael can send me your shipping address.

Best,

G.

I’ve got an answer today – they don’t sell outside the Lectron Shop and have reduced their team because of decreasing interest in Lectron.

They honor good old customers and would make an exception (!). They ask for the number of motors and would take them from the planned – and available – set 1603. The manual may be viewed  here.

Therefore, I immediately need the number of desired motors #2603 – possibly also for future interested parties and would receive them. Billing etc. would then have to go through me because I give my name etc. – probably the only way to the goal …

Please decide now – the only chance for us!

May be that this way is the only one to get also other rare blocks (e.g. blocks with transistor sockets), so do not hesitate to take this (last?) chance…

Best,

G.

Hello fellow Lectroneers,
I have added a link to the 1603 model page on Lectron.Info and also the link to the manual in Guenther’s post above.
This is what I thought was going to happen.  The management team is letting the Lectron System product line die without any further marketing, development or sales campaigns.

Guenther is acting wisely, get the parts while you can.

This change is a major negative blow on our beloved Lectron System.  From my last visit in 2019, there are ample supplies and as they are only selling to people if they come directly to the ‘store’, this will perhaps delay supplies exhaustion unless the management team decides to stop all Lectron System activity.

What a shame that the end appears very near!

With heavy heart,
Michael

Hi all,

What a shame to hear this sad news.

I was just planning a large order. Should I continue with this if they don’t seem to send it ?

I will ask Martin Pohl about this.He also sent me a mail with  information about some parts.

Greetings

Hi Frank,

I am sure that you can place your order with confidence of it being filled.  Martin will take care of things for you.  You can keep me in the loop and I will be glad to follow up.

I have written to Martin today with the hopes of hearing back from him with more details about the disposition of the Lectron System.  Since you have been a loyal past customer, I think that Martin would support sending you a large order!  

Thanks as always to you and Guenther for keeping Lectron.Info a lively and vibrant place!  I will be resuming my work of completing the individual pages very soon.  I added a page for the 1603 model after noting that I had not originally created one when Guenther mentioned it in his Lectron Motor page.

Best,
Michael

Hi fellow Lectroneers,

for clarification: they will sell everything what is shown in their Lectron Web Shop. Only special requests, like the “simple” motor without the complete application set – or any other block(s) which is / are not within their actual offerings, may make problems.

So again: I need the number of wanted motors for a quick answer  and response – otherwise  I would make a fool of myself for making so much fuss in Frankfurt…

Perhaps I should ask for the “old” transistor blocks with a socket (to use own / special transistors). I will ask for some old RTL / DTL blocks of the Ausbau 3 set, icl. the steel cassette trays.  I guess the still existing blocks are defect, even the 2-stage amplifiers, but I may repair or dismantle these Also for some of the very first demo blocks – they never can sale them!

Best,

G.

Hello Guenther,

Thank you for your clarification.

I got a mail from Mr Martin Pohl saying that he has the digital meter and FM tuner block.

Can you get the motor 2603 (with side magnets) for me ?

This would be cool to use in circuits.

I already made up a (long) list of Lectron blocks to order. This motor seems hard to get hold on. Thank you for your offering.

Greetings

[GuentherParticipant]

Hi Frank,

I had some hope that I will get the motor #2603 from Lectron – Mr. Steffen Pohl wrote, that he would like to know how many motors – and his son Martin wrote, that even the #1603 complete Motor Set (for Michael) cannot be delivered (to me?).

I have no words – so I offer my motor #2603 to you – please let me know your (e-mail) address for detailed contacts.

Best,

G.

Hello Guenther,

Thank you for your kind offer. I will gladly pay you for this.

But let us wait for the answer from Martin when I ordered a lot of modules (including the motor). He asked for patience due to the Corona illness.

It seems that Lectron plays hard to get 🙄

I will gladly give you my address, perhaps it can be provided by Michael so I will contact him.

Big thanks
