In Moscow are two new MTRZ-5279.2 trolleybuses with asyncron eletrics. From which manufacturers are the regullation? (Dynamo?, CEGELEC?, SKODA?) From wich manufactures are the motor?
Is there to technical information?

Regards
Mattis at Berlin

Correctly the model is writen MTRZ-52791.0000010. Them 3 pieces. Eletrics from SKODA. Numbers of machines 4000 (skilled), 4008 and 1012 .

Wait wait wait, gentlemen! I expect Mattis to understand difference between 52791 and 5279.2. So, it seems to me, that Mattis is asking just about 5279.2. If Mattis is interested in 5279.2, I’ll add, that the numbers of two machines are 1008 & 2014, asynchronic traction equipment and AC traction motors are Russian made. The manufacturer of traction motor is unknown for me, the control was developed by EPRO (Saint-Petersburg) and Elektrotransservis (Moscow) in cooperation. If some technical data is required – I’ll try to look for it.

Everything said about 52791 low-floor trolley is correct, except of traction control. 52791 is not asynchronic – it has IGBT-transistor control of DC motor. Both the control system and the motor are manufactured by Љkoda Elektrik.

It is a two different models: (see http://mtb-photo.narod.ru/dl/32.htm)
MTRZ-52791.0000010 - it is a low-floor trolleybus with body from LiAZ-5292 bus.
Electrical eqipment from "Skoda electric"


МТРЗ 5279.2-000010 - it is a "normal" trolleybus in body LiAZ-5256 and asyncron eletrics so. Them - 2 pieces - 1008 and 2014.
Asyncron motor "ТАД 280" bulid by "ETK Dynamo".
Regullation "ЭРПОТЭТ 180-1" bulid by NPP ERPO, Sankt-Peterburg.

I' m very interested in information of the electrical parts:

NO!!!
4007 is the MTRZ-6223-000010 type trolley. It has the ZiU-9 based body and construction , but realy with PTKD-203 IGBT-control of DC engine :)

PTKD-203 is a transistor-puls regulator for DC motor. Produced by ChERGOS (Saint-Petersburg). The PTKD-203 controlled trolleys are equipped with 170kW DYNAMO DC-motors DK-211BM.

Yes. They were delivered to the depots at the early begining of 2004.

5279.1 with rheostatic control based on typal shema KR-3001. Originally it was developed by DINAMO, but now it can be mounted by any trolley manufacturer from number of standart parts. Also it can be bougt from DYNAMO. Equipped with 115kW DYNAMO DC-motor DK-213A, or its analogs with index "213", produced by other manufacturers. Moscow built trolleys are likely equipped with original DYNAMO control and engines.

Artem already described.


Yes.

> MTRZ-52791 "Garden circle" with SKODA-IGBT regulations

Garden Circle is not the best translation :) this is the name of the street in Moscow. So the best variant is not to translate it at all and call it "Sadovoe Koltso" or "Sadko". If you want to translate, then "Garden bRing"

+7 trolleybuses are now in building :^)

Many thanks on all writers!!!

For 5279.2 TAD-280 is of 180kW
For Skoda regulation in one of the booklets was mentioned motor of type 9ALS2943RN of power 135kW
