When i rectify 240 I get 280 DC when i rectify 120 I get 130 DC why do I gain 40 volts on 240 and 10 volts on 120? Since I get 130
from 120 what besides a transformer can I do to get the correct voltage? The motor seems to hum on 130 and wine on 280 but it does
work on both.. Since I get 130 from 120 what can be done to operate a 90 volt dc motor?
Do you have an idea on how to make a speed control besides a varac?
Sorry for the 50 questions.
