The power supply for your 38V motors should be around 44V (+15%). 50V is not so far above so I think they will run just fine. Surely they will heat a little more but this should be examined during testing.
As a reference I have my 56V-rated motors running with a 66V PS. Of course if you are not going to use the full speed potential of your motors you could definetely go with a lower voltage PS - say 35-40V.
