This paper present a load compressor fed Brushless DC motor for solar power air conditioner under variable air conditions. At current scenario, air conditioners are manufactured according to room size and space with available of objects present in the room.The output of the air conditioner cannot be alternatively changed. This problem is overcome by modify the fixed output of the air conditioner using BLDC motor. The BLDC motor performance is superior when compared to other motor. Solar power is used as the main source which is a renewable energy and readily available and also very useful for the future generation. This work deals with the output of the air conditioner can be alternatively changed according to the size of the room by varying the speed of Brushless DC motor.
