Design and Implementation of an Electric Bicycle Using BLDC Motor with Optimized SVPWM Technique

This paper details the design and development of an eco-friendly electric bicycle tailored for urban transportation. Driven by a need for sustainable solutions, it integrates a Brushless DC (BLDC) motor into a conventional bike frame. The study outlines design, simulation, and implementation, focusing on efficiency, user experience, and performance. A BLDC motor with a three-phase inverter enables variable speed control, enhancing ride quality over traditional pedal bikes. Using Space Vector PWM (SVPWM), motor torque and speed are optimized, reducing harmonic distortion to 43%, a marked improvement over SPWM techniques. A battery management system (BMS) handles power regulation. Results demonstrate a successful electric bike prototype, with recommendations for solar charging integration to extend range. This project supports the shift to cleaner transportation.
