  • Abstract This thesis proposes a method of sensorless and variable speed driver with the Digital Signal Processor (DSP) as the control kernel for the fan driver. The sensorless method is the variable voltage variable frequency control method in which the commutation process can directly be achieved. The information of rotor position can be detected to estimate the speed by the back electromotive force signals. In order to verify efficiency of the system, this thesis builds the experimental system structure, and the advantages and the improvement of efficiency of the system with sensorless driver were be verified by software simulation and experiment. The result of experiment expresses better than the traditional motor control method.
