How is torque affected when converting from AC to DC?

Question

I know that torque wise, DC is much stronger than AC. So, I am wondering what would happen if I converted AC to DC and gave power to a DC motor?

The motor in question is actually a large Servo DC motor, that has 5 hp and runs at 320 V. So, what I'm going to do is convert the Servo Motor into a DC motor, and then put a 10 Amp Step-Up transformer that has 220 V as input and 320 V as output, and then I'm going to use a large Full-wave bridge rectifier (using those large diodes) and of course the corresponding capacitors on the other end (corresponding for the application) to run the motor directly.

The thing is that I don't have the drive for the Servo motor, nor does it exist standalone, so I'm forced to go with this for now. My question is: How is torque affected here, and will setting up the bridge directly the way described work?

I am confused. You are going to convert a DC motor to a DC motor?

Based on your comment as long as the supply of DC power is adequate then the amount of torque should be the same. As to the effectiveness of the system you have tried to describe, I don't think there is sufficient information to determine if it adequate.
