Keywords:Electric bicycle, PMBLDC motor, PWM, Lithium ion battery, Inverter, Sensor control, MATLAB, Modeling and simulation.
The development of internal combustion engine automobiles is one of the greatest achie vements of modern
technology. However, the highly developed automotive industry and the increasingly large number of automobiles in use
around the world are causing serious problems for the environment and hydrocarbon resources. The deteriorating air
quality, global warming issues, and depleting petroleum resources are becoming serious threats to modern life.
Progressively more rigorous emissions and fuel efficiency standards are stimulating the aggressive development of safer,
cleaner, and more efficient vehicles. It is now well recognized that electric, hybrid electric, and fuel-cell powered drive
train technologies are the most promising vehicle solutions for the foreseeable future. Now today traffic problem is
more. So for reducing the traffic problem electric bicycle is useful now-a-days. There are different types of motor used
like Induction Motor (IM), Permanent Magnet Brushless DC Motor (PMBLDC), Switched Reluctance Motor (SRM),
Brushed DC motor for electric vehicle. According to high efficiency, construction, high torque to weight ratio PMBLDC
motor widely used. There are different types of battery used for electric vehicle. We can also make modeling of electric
bicycle with various parameters. In this paper modeling and simulation for speed control of PMBLDC motor with the
help of PWM technique is explained. And get various simulation results with different duty ratio
