Why try 2000rpm? 3600 is common iirc. A whole range is needed.

But if am testing without load I should be able to get the 600 v dc why am only getting 400 v dc at 2000 rpm
To get 1.5 times the voltage you need to cut the field at 1.5 times faster, so maybe you should really be spinning it at 3000 RPM.

2 pole at 50 Hz, synchronous = 3000 RPM, induction with 4% slip = 2880 RPM.
2 pole at 60 Hz, synchronous = 3600 RPM, induction with 4% slip = 3450 RPM.

You need a revs / volts curve with no load and with whatever load you can get hold of.
You surely can’t believe that you can do better with a home made machine at any particular speed.
