“…The new energy condition or the new possible solution x i+1 is defined with the Boltzmann's distribution: (10) Boltzmann's constant has a scaling role in the SA method and in most cases it has the value of 1. For ∆E ≤ 0 relation (9) gives P[E i+1 ] = 1 where point x i+1 is always accepted. This is a logical choice in the context of minimization of the objective function, where value f i+1 = f(x i+1 ) is lower than f i = f(x i ).…”

The main objective of this research was to propose a light and practical design solution for electric bike front drive with bottom bracket electric motor. The initial design needs to be redesigned so it can enable simultaneous use of the electric drive and pedal drive, with integration of the front gear shifter. After gathering the basic information linked to the problem and inspecting the initial design solution, the assets and flaws have been identified. The CAD models of the considered possible solutions were developed into FEM models which were used for structural analysis in CAD/CAE software system CATIA. On the basis of the FEM analysis and additional criteria, the optimal solution was chosen, and structural optimization, based on FEM model, was performed. A prototype was manufactured and a mounting process in a place of the initial design was performed. Afterwards, electric bike with mounted prototype was tested under real conditions.

“…BLDC machines have higher torque ripples, however for e-bikes with a large mass inertia and high gearing ratios (acting as dampers to the pulsating torque) this is not concerning. SRMs have been studied as an alternative cheaper motor in e-bikes [6,[15][16][17]. Most of these studies have focused on optimizing the SRM design for maximum output torque, output power and efficiency [15][16][17][18].…”

Most of these studies have focused on optimizing the SRM design for maximum output torque, output power and efficiency [15][16][17][18]. When the outer diameter of an e-bike motor is kept as a fixed parameter, and the SRM is optimized for its weight, it is shown that the BLDC motor has higher efficiency than SRM [16].…”

The prospect of physical exertion commonly acts as a deterrent to the adoption of cycling for everyday transport. A battery powered assistance torque electric motor could alleviate such physical exertion by reducing the effort required by the cyclist. This study investigates the potential effectiveness, efficiency, and energy saving of electrically-assisted cycling when assistance torque of a switched reluctance motor is designed to vary in accord to the cyclist instantaneous torque at the pedal cranks. Specifically, the modulated motor assistance torque is delivered at the least efficient human input torque points on the cycle. For a representative short distance cycling schedule modulating the instantaneous torque of the on-board electric motor causes the electric energy expenditure to not exceed that of the assisted cycling mode of an identical constant-torque motor. Furthermore, for the same speed profile cycling journey with added road gradient and head wind resistance, the energy expenditure of the modulated torque motor is equal to the constant torque motor. These findings indicate significant improvements in the cycling experience. INDEX TERMS modulated cycling torque, energy conversion, electric bike, switched reluctance machine, battery.

Aim/ Objectives: The aim of this research work is to design and implement a low cost electric bike to use for day to day activities, to analyze the mileage of the bike for every charging per hour. Method: Initially the model of Hbridge driver circuitry is created to drive the BLDC motor in Proteus simulation software. PWM pulses are fed to H-bridge driver circuitry and response of the BLDC motor is studied. The speed control mechanism of BLDC motor driver is studied in simulation. Then the H-bridge converter circuitry is designed and developed to drive the BLDC motor. The assembly of BLDC motor and tyre is selected which act as rear wheel. The system is designed around Arduino microcontroller. Lithium ion battery is used to supply power. Program is developed for Arduino Uno microcontroller to generate PWM pulses which are fed to H-bridge driver. The performance of the BLDC motor driver is analyzed. After precise control of the motor and tyre assembly, the other subsystems like speedometer, indicator, accelerator, horn, braking system etc. are developed and tested. Motor controller and status monitoring controller acts in coordination due to which in any faulty or abnormality situation both interacts with each other to take necessary action. Finally the mechanical assembly and chassis is designed and developed. Findings: The bike developed in this work is found to be useful for day to day domestic uses. The maximum speed of 40km/ hr is achieved and upon charging for nearly 3 hours it travels around 70km. Keywords: Low cost E-bike; electric vehicle; BLDC motor driver; microcontroller based E-bike
