BLDC motor also known as electronically commutated motor is widely used for many industrial and commercial, low power motor drive applications. A simple BLDC motor is energized by DC electricity through an inverter or switching power supply, which produces an AC current to generate magnetic field in order to drive the motor. With the growing energy need and increasing environmental concern, alternatives to the list of non-renewable fuels have to be investigated. One such alternative is the solar energy. The use of solar energy to drive BLDC motors requires the need to develop the controller for the same to reduce the running cost of the motor. The main contribution of the paper is towards designing of a simple , low cost ,efficient ,solar energy based control mechanism for low power sensor less BLDC motor with effective control strategy using general purpose ATmega328P ,pulse width modulation(PWM) circuitry and power output stage .
