Energy Efficient Brushless Direct Current Motor Based Leaf Collector

A massive amount of leaves is shedded from the trees in parks and gardens. Cleaning of these leaves is a major task and it becomes more difficult especially in the autumn season. The conventional cleaning process is done by persons using brooms, fanrakes etc. It requires more manpower and consumes more time in cleaning the shedded leaves. Hence an equipment is needed for cleaning the leaves which is generally known as a vacuum cleaner. In conventional vacuum cleaners universal motor is used to drive the suction fan. Universal motor has some disadvantages like low efficiency, sparking due to presence of commutator and brushes, noise pollution etc. The concept of the project is to replace the universal motor with a Brushless DC motor (BLDC) in leaf collectors and thus to overcome the disadvantages of universal motor and to have a better and efficient cleaning process. These leaf collectors can be used in home gardens, hospitals, educational institutions as well as in the industries.
