The thesis describes the design,experiment and invention for the Dynamometer , using the theory of DC Machine consist Motor and Generator. We used Current Regulator for control DC Generator’s braking , work as a Dynamometer and control motor’s speed. About Speed Control in braking state , we used Proportional Control to control close loop that uses feedback signal from Tachogenerator. In display part we use the computer that connect with Microcontroller AT89S8252 Board and I2C Board too. Program show the value of Torque , Speed and Power from testing motor on monitor and control Dynamometer for a moment time. The control program is written by Visual Basic 6.0
