I am planning to run 230V single phase machine with 460V single phase supply. what will be the effects in RPM and torque??? (( this is how i thought: as we increase voltage , current will decrease since power is same...decrease in current decreases the torque.....to maintain same power, decrease in torque is counteracted by increase in speed....SO MY CONCLUSION IS THAT IF I INCREASE VOLTAGE MY SPEED WILL INCREASE AND TORQUE WILL DECREASE....IS THAT RIGHT???? WHAT PERCENTAGE THE SPEED WILL INCREASE AND TORQUE WILL DECREASE????)) AND MY CONSTRAINT IS THAT I HAVE TO MAINTAIN SAME RPM!! WHAT CHANGES SHOULD I NEED SO THAT 460V AND 230V PRODUCES SAME PERFORMANCE!!! I will be very thankful for your help.
