Alternator - Higher Amp Stator

[Nishan.dj]

Hi Experts,

This is regarding an alternator enhancement. I have gone through many articles and posts such as http://www.google.com/patents/US5874822 to find out how an alternator can be modified to provide more power without going to replace the whole unit. (Keeping housing and brackets as original) The major part that most people replaced is the Stator.

With a higher AMP stator for the existing alternator will increase the power that it produces. But I couldn't find any related article about Stator replacement efficiency comparison with RPM ratio. When it comes to diesel engines, the idle RPM is bit lower which could be 500-600. By supposing that we can increase it up to 1000 or 1100 by changing the pulley system, is it possible to have a higher amp stator for exising rotor? Kindly need advises from your practical experiences. Thanks.

Hello there,

I hear nothing for this post. Some has PM me and thanks to all of them.

Mr. Sylvi suggested me to have a pulley conversion to increase the rpm of the alternator and it went well and also conversion from star to delta of the stator winding.

Also I could get it converted to IC Regulated alternator to get the max power out whenever the rpm is high. So the old classic cut off switch was removed.

There is another thought of having a dual alternator system but I have no knowledge about it as how it effects to the engine and stuff. So need experts replies on that matter and I really appreciate it. Still the outcome is not at satisfactory level and as I started the thread, If anyone knows how to get some higher out put (Amps) at lower RPM, please kindly reply. Thanks again.
