VERY RARE Micromotors 2986 from the 90'
QQriQ replied to QQriQ's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
the micromotor production and LMM Ltd. was part of the most well-known Hungarian TV program at the time, which presented the technological innovations of the world 25-30 years ago -

Yes the magnet powder is closing the gap in the wrong micromotors. But I am very curiosity how could you close back the motor that the metal connectors (brushes) did not damaged. For this we had a specia tool. two tiny needle was put to the holes in the buttom of the motor which pushed away the brushes from the rotor's segments. while the motorhouse was push togetherwith the gearhouse. Is The motor what you repair was Mini-motor or micromotor.? Because there were a same problem with the mini-motor's magnets. but Mini-motors magnets got a nickel layer and here much more easier to open and reclose the motor. And in the mini-motor there are nickel "flakes" but in the micromotors there are magnet dush. -

Yes, i would like to sell them. I have just working on it, I started to "collect" the offers. But only 6 of the transparent micrromotors turning well.(i tested them some days ago) and my 1 pc transparent 9v Mini-motor with "goldened iron parts" . It is odd parts too, because only hundred pcs were produced (every workers got one pc as last gift, when LEGO sold and closed the company in Budapest. https://www.flickr.com/gp/189156800@N06/5dLz9h -

Sorry for my late answer. Yes, on the bottom of the motors there is a date "stamping" but i don't remember exactly to the rule how was it change. We had a time tabel which showed when we had to change the "hot stampper" tool and to what and unfortunately I don't remember when was the magnet supplier changing. I was "only" a blue collar" workers in this time but i think only the first some thousend pcs were made from VC magnets. -

"the unfortunate fate of all these motors" Not the all micromotor got cheap chinese magnet. In the first xy hundred thousand pieces got vacuumschmelze's magnets. So the older motor's magnets much more better, They do not "crumbling" -

you can easy to see if you have "the crumbled magnet" problem on transparent motors. Turn the motor in the direction of strong light and look over its side. the magnet is the upper side above the rotor (under the rotor there is a simple iron in plastic holder) You should see a little gap between the magnet and rotor and same gap between the rotor and the Iron. It is clearly seeing in my cutted motor picture. But if the motor is whistles is means the rotor is turning so it is not magnet problem. -

Yes, I have motor with transparent shaft and red ring; transparent shaft and transparent ring; transparent shaft with black shaft and you have transparent ring and RED shaft. The reason of this is simple. We produced colorful output shafts and rings too, for the colorful (not red) motors. (only a few pcs from each parts) BUT when we started to assemble them, we recognised the planetary gear tightens with the color gears. That's why we could not use them for the color motors. We produced only a few color parts and we did not try them immediately. We got problem when we tried assembly. The issue (tightens) was caused by the original "output shaft" (black) was moulded from Hostaform not from ABS. And the Hostaform's moulding parameter is totaly different as ABS. So we had to trow out almost the all color shaft, but some of them worked in the transparent motors. (only in the transparent) The all assembly proces was not easy with the "special" parts and we have limited pcs. We had to pairing the parts and try them together lot of times. If the motor did not worked we try with it with other parts until they started to work. This parts is very precis and little different could cause a problem. So it was a luck that the your motor run with red shaft :-) Your motor is the RAREST rare motor. -

"Is there a non-destructive way to open these motors?" Yes, there is. BUT You need a "simple tool" to open the motor house. and one other to open the Gearbox. For the motor opening: You can see 4 hole in the top of the motor. if you push in 4 pins at same time to here, motor will open. For the Gearbox opening: You need a special pinchers with the profil of drive wheel. If you pull the drive whell up with this pincher the locking ring will pop up and you can take out the planetary gear and the planetary cog wheel and the parrel. I am absulutely sure that the raison of wrong motors is the magnet. and if you could open the motor , very complicate would be clean the magnet. but even if it succeeds you sholud snaps together the motor again. and for this you need a special tool too. If you see the bottom of the motor you see two little kidney shaped hole. here should push in two very thin needles, and "move" the brushs to the rotor's collector that they do not demage while you pushing the gerbox and the motorhous together again. It is not easy. and the magnet which started to crumbling will not stop the pulverization. And change the magnet is not possible. No we did not make dark gray micromotors. (I do not why. We have lot of grey ABS because we produced the all plastic parts for Mini Motor (injection molding) :-) ) I hope you understand my wrong english :-) -

I and my "old" college have some pcs from these motors, if he have not sold or thrown out them. (I do not know this because i did not meet or talk with him in the last 20 years :-( ) Yesterday I went to my garage and I made inventory about my rare parts. I took more photose but i can not upload here because only 100 Kb upload allowed me here. (????? in 2020 ?????) I have 4-4 pcs yellow and purple and 5-5 pcs blue and green and 9 pcs transparent motors. Yesterday I tested them again (last time lot of years ago all of them was good) BUT NOW only 1/3 of them working :-( :-( I dismantled one transparent motor and i saw the typical problem which we had with micromotors and Mini-motors too. The magnet was crumbled. and the magnet dust clogged the little gap between rotor and magnet :-( We used powder metallurgy magnets what we order from China. Lot of magnet started to crumble after some months the magnetizing. Unfortunately It was known problem. -
VERY RARE Mini-Motor 43362
QQriQ posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
It is one more very rare motor from my "collection" Now I would like to sell it, but I do not know how much can it cost. How much can I ask for it? Story: These transparent motors were made in Hungary (where the all Mini-motor were produced). When the LEGO sold the company, the all workers got one pcs from this transparent and gold-colored motors as memories. Only about 50-150 pcs were produced. The motor is in good condition, well working and never used -

I think it would be much more interesting to display this motor in Billund. This is one Segmented micromotor. The motor's all parts were cut and after it assembled. :-) As I know only this one exists. it is my other rare motor -

:-) We did not think to sell the motors. it was just an idea of a few bored workers. :-) We made them for ourselves for fun :-) But I have just realised what a big sin we commited. I am thinking about i will sent my all rare things to Billund with one apology letter or i will throw out them ;-) -

The motor was designed by BRG about 1989-90. BRG was the biggest Radio Technic Company in Hungary. It mainly produced equipments to the Russia market (military) when the communist regime fails the company lost the all market and went bankrupt. This time the motor and the production technik was 95% ready, so the LEGO establish the LMM Kft-t (LMM Ltd) LMM short form of Lego Micro Motors. Until the produktion did not start we were about 10-20, but later the staff increased to 280-300 persons. We designed and started to produce the motor 43362 (we called GEAR motor) and lot of products were moved from Billund to LMM e.g. RCX, Train motors, Basic motor, Mybot, watches and lot of other thing The company was 100% LEGO property but to be honest I can counting in my left hand how many times we saw leaders or visitors from Billund. This times were different as you wrote !!
