Question 4: DC machine calculations Draw the torque-speed steady state characteristics of the load and the electrical machine for three different points (different speeds, different loads...) • You must get the electrical a mechanical data from the catalogue What type of connection do you use for your machine (independent, series, parallel, compound)? Why? For the three plotted points, calculate the power and current absorbed from the energy source. Assume an ideal variable voltage source Based on week 5 material, describe how you would control the speed of your drive
