two speed motor (parametres)toCMOTEJUNAS

[nayka]

hello,i have asked this question by 19 sept, and having,then, been desapointed ,by chance ,today ,i 've found that some one have been interested to help me(cmotejunas)

so ,i have now a new handle as :nayka ,and i renew my question: number of poles:ratio that is 4(high speed)/12(low speed);please if you have only a catalogue's data so try to provide my with the ratio of max torque /nominal torque ,the data that sometimes Do not exist in catalogues.
QUESTION OF 19 SEPT:[NB:the motor is meant to be used in lifts :rgime of work S3]
i'm dealing with a two speed induction motor (with two winding on the stator)power witch is 5kwt.to calculate the mechanical charateristics for the high speed and the low one,and the transient regime i would need electric parametres,moment of inertia and so on.so any one have catalogues or any papers or book where is shown the parametres of such motors(rating of 5kwt) so i hope to take care for my hope to help.
many thanks in advance

Suggestion: Visit

http://www.the-motorco.com/distributors/

http://www.dealerselectric.com/

(and click on "multispeed". They even have 5kW multispeed motors used.)
etc. for more info.

hallo jbartos,and thank you for your interest to my question .i have consulted the document that you have recomended me(multispeed),but unfortunatly ,there no parametres there(only the power and the ratio of speed are shown).thus i continue to ask for parametres (poles 4/12);may be cmotijunas can help me.
i'm in wait ,and i need this data as soon as it would possible.thank you in advance

Suggestion: Check with

http://www.dealerselectric.com/

about the multispeed motor nameplate parameters. They have several of them. Else,
Contact motor manufacturers, e.g.

http://www.baldor.com

http://www.reliance.com/docs_onl/online_motor.htm

for more info.
Notice, that 1800RPM High / 600RPM Low motor is somewhat on a custom made side.

hello again,
*Nothing was in help(i mean adresses that u gave me).
About motor manufactures(leroy somer and others itlian and) ,i had already asked them several times ,had wrote and wrote and it apears me that their interest is rather money(to sell their products) than anything else ,i was realy disapointed ,so that i have a last hope to eng-tips to help.
*Men that work upon transient processes and having dealing with 2-speed induction motor may have those data.
if it is not available the data of: poles(4/12),so provide me with the (4/8);
*the data that i need :r1,x1 of stator(first winding),r1,x1(for the second winding),r2,x2 for the rotor ,rm,xm(magnitude circuit ),moment of inetia or:
*the catalogues data : nominal speed ,the ratio of:IMAX/INOMINAL;Cmax/Cnominal;Istart/Inominal;Cstart/Cnominal;cosphi and N,and the moment of inertia.
the rated power as 5kw.
THANK YOU IN ADVANCE.

thanks to all ,if any one will find something ,don't forget to provide me with
