In recent years, the highly growth and development of world economy results in the natural resources being gradually run out and the environment further directly and indirectly being polluted more severe. Consequently, any kind of alternative energy resource have been developed, harvested and designed. An electric bicycle based on a blushless dc motor drive which has high efficiency, zero pollution, clean and convenient, is then designed and implemented in this paper. The hardware design based on a microcontroller is analyzed and discussed. The software programming is developed in MPLAB integrated development environment from the Microchip Technology Inc. Finally, a prototype of blushless dc motor drive for an electric bicycle is realized and demonstrated. The experimental results show the feasibility and fidelity of the complete designed system.
