Synchronous induction motors - do you still use them?

Synchronous induction motors - do you still use them, need a replacement or a new motor?

ABB manufacture these machine. What data do the old motor have, that you need to replace?

WEG produce them both as drop in for existing or new one.
Just contact your local WEG center or our web page WEG.net.
If you have any problem with above just contact me and I will per solely help you.

Hi Martin
Induction generators are still used for their simplicity and low cost compared to synchronous alternatives. They are nevertheless less efficient, hence generally called for between a few hundred kW to around 3MW. Most manufacturers would be able to offer you an option to what you currently have on site. If you wish I can connect you with engineers in your region who could assist further.
Regards
Alex

Thanks all, however, I was talking about, say, 2MW 6.6kV 12-pole synchronous induction motors used as fan drives, in mining or cement and pulp&paper industries for high starting torque, low starting current, PF compensation, no harmonics and repairable by local workshop type of machines.

Yes it is a good alternative to a standard motor design do to cost and effiency.
If needed please contact WEG UK or find design and spec on WEG.Net

God weekend to all

Tatung Can offer a drop in replacement or a new design as well. These are very common in Pulp and paper Not so much in mining

Hi Martin,

I believe there is some confusion on your request... you either need a synchronous motor or an induction motor (asynchronous). If you are looking for a replacement that matches existent motor footprint, CG can build one. Just email me at marcelo.oliveira@cgglobal.com and I will get you some required information for us to present you with a proposal.

Best regards,

Marcelo.

For motors with less power you can used a pure copper rotor in high pressure die cast for your asynchron motors from Favi

Your all Missing the Point, I think he wants to make them for you, (do you still use them?? need a replacement??)
