Dc motor, Electrical Engineering

You have been given a DC motor to characterize. What three measurements are required in order to develop the torque-speed curve and the acceleration curve for the unloaded motor?

Draw a diagram of the test set-up for any two of the measurements from question 1. The diagrams must be neatly drawn. Clearly identify the measurement being made, all electrical signals, measuring equipment, and the motor under test. In 3 sentences, maximum, for each set-up, describe how the results are interpreted.
