Brushless dc (BLDC) motors are electronic controlled and have the rotor position for commutating the stator winding current. This paper presents the BLDC motor sensor less speed control system with fuzzy logic implementation. The sensor less method based on the back EMF sensing and the rotor position detection with a high starting torque is suggested. This Paper presents the efficient power generation of Photovoltaic System and deal with the sensor less control of BLDC motor. The controller design of a solar module has established for maximum power. It consists of a solar panel and boost converter for maximum power generations. This boost converter can be operating step up mode with less passive component counts and non-inverted output voltage polarity. The sensor less control of BLDC motor based on fuzzy control and a potential start-up method with a high starting torque are indicated. The rotor position is adjusted at standstill for high starting torque. The stator current can be changed by modulating the pulse width of switching devices during alignment. The controller performance of solar module and corresponding simulation results are verified by using MATLAB/Simulink environment.
