Electric vehicle is an alternative to substitute internal combustion engine when fuel availability is difficult to obtain. Electric energy can be obtained from renewable energy and non-renewable energy. Electric vehicles like electric scooters consist of many parts. The parts used in an electric scooter have requirements such as reliability, safety, good performance, and high efficiency. Brushless direct current (BLDC) motor controller is one of the main components in the electric scooter. This paper presents a design and performance test of the BLDC motor controller. The controller uses PID current control with six step commutation in a trapezoidal control. The motor current ripple is eliminated by using a digital isolator. Tests were carried out using an Eddy Current Dynamometer. The results show that the current ripple is sucessfuly reduced which makes the controller suitable for electric scooter applications.

The BLDC motor is an electronically commutated dc motor becoming very popular in many applications. There are various speed control methods used for BLDC motor. The performance of BLDC motor drives can be improved using sensored control techniques over sensorless technology. This paper presents Brushless Direct Current motor drive system and its sensored speed control technique with PWM. Advantages and limitations of sensorless techniques are reviewed and then, sensored speed control technique is introduced with their advantages, performance analysis, practical implementation and applications. Torque and speed behavior during clockwise and anticlockwise motion, use of hall sensors to detect rotor position, speed control technique using PWM method are discussed in detail. Detailed hardware design its implementation and experimental results covered. This paper also covers performance analysis of BLDC motor using experimental results.

This research paper gives the theoretical aspects of impact of Electric motors practically on every part of modern living. Likewise, they are additionally in charge of an extensive bit of mechanical process. The Permanent magnet brushless DC (PMBLDC) motor is getting to be noticeably mainstream in different applications due to its high effectiveness, high power factor, high torque, basic control and lower upkeep. BLDC motor is one sort of synchronous motor, which can be worked in perilous air condition and at high speeds because of nonattendance of brushes. What's more, the proportion of torque conveyed to the extent of the motor is higher, making it valuable in applications where space and weight are basic elements.

The Main purpose of the Electric Tricycle Project is to bring increased mobility to disabled persons in Maharashtra, India. Presently, hand-powered tricycles are used by many of the disabled in this community, but some current users of the hand-powered tricycles do not have the physical strength or coordination to propel themselves on the tricycle with their arms and hands. The aim of this project is to add an electric power train and control system to the current hand-powered tricycle to provide tricycle users with improved levels of mobility, facilitating freedom in travel and contribution to the community and functional. In response to the request from a SIM missionary at the Handicap Center in Pune, committed to designing and supplying a kit to add electric motor power to the current tricycle design, and we, MD PATIL, Sunny, Santo, AJ, MP, Sujya partnered with their commitment.

The creation of Electric Bicycle gives many advantages in our lives. This thesis is focused on the type of motor that used on the electric bicycle, the type of motor that were used on the electric bicycle is Brushless DC (BLDC) motor. The BLDC motor provides many advantages to the electric bicycle, it provide lots of benefits to the user. It is not only for electric bicycle it can be used to lot of machines. By the way, the characteristic of BLDC motor make it majorly being used around the world, this is because it has high efficiency, long life duration and more durable compared to other motor. The BLDC motor were widely been used on most type of the electric bicycle which is most compatible with it. The used of BLDC motor on the bicycle give the bicycle maximum performances and can travel longer with certain level.

Persons with disabilities are people who have limited activities like people in general due to physical disability or paralysis, especially for mobility although there are many tools specifically for people with disabilities, for example wheelchairs certainly these aids may not fully help for example for to travel quite far. This raises its own concerns for people with disabilities because they have limitations to do activities like other people. This research was conducted with the aim of designing a motor control system BLDC on electric motorbikes with disabilities. The BLDC motor used is type 350 Watt. The method used for motor speed regulation is PWM Six-Step Commutation. Arduino is used to implement the method. With the controller the BLDC motor speed can be easily regulated. For find out the performance of the controller carried out several tests namely measuring the voltage value and electric current at the three-phase input and output drivers and measuring the rotational spe...

The aim of this work is the design of an electrical drive for a motorized bicycle, characterised by new solutions for the control method and the regenerative braking system. A dynamic model of the vehicle has been realised, and the characteristics of the drive have been individuated. An effective closed-loop control strategy has been studied, adjusting the motor torque and the current in order to increase the availability range. Finally, a feasibility study of a regenerative braking system based on the supercapacitor technology has been carried out. All the components of the drive have been selected among the models available on the market. In the paper the results of the simulations are presented and other technical-economical aspects such as energy consumption and costs are also briefly discussed.

One of the problems arising in the conversion of pedal-based bicycles into electric bicycles using brushless direct current (BLDC) motors is how to provide an electric braking system for the BLDC motor. Published research on braking systems for electric bicycles from a practical perspective was still limited. The objective of the article is to develop an electric braking system for BLDC motor as a propulsion of electric bicycle converted from pedal-based bicycle from the empirical point of view. The pedal-based bicycle was converted to the electric bicycle by fully replacing its rear wheel including its chain system with the BLDC motor. The braking system was developed by adding a DC motor as a load for BLDC in the braking mode. Test was conducted by turning on the acceleration handle and then the braking action was applied. The stoppage time was recorded from the start of braking action until the wheel was fully stopped. The test results showed that the addition of a direct current (DC) motor as a load can shorten stoppage time of the electric bicycle dramatically, i.e., needs 1.65 seconds compared to 10.14 seconds and 3.09 seconds for without braking and with braking but without DC motor as a load respectively.

This paper briefly describes the composition of electric power steering (EPS) system and the development advantages of brushless DC (BLDC) motor. Based on the mathematical model of the BLDC motor and the requirements of the EPS system for assist motor, a control strategy of the BLDC motor used in EPS system is proposed, then a simulation model of control system using in BLDC motor is set up, and its simulation analysis is made. The feasibility, high reliability of the system and the validity of the control method are proved by the fruitful simulation results which serve a design method for a further research of BLDC motor in EPS.

BLDC motor is the permanent magnet synchronous motor designed to have a trapezoidal back emf. Due to rugged construction, less control complexity, higher power density, variable speed over a wide range and flexibility to select the rotor construction suitable for particular application, it is being viewed as an alternative for conventional a.c. motors right from residential to commercial & aerospace systems. Rotation of BLDC motor is achieved by energizing the stator phases in a sequence, which depends on the rotor position. Hall sensors are used to detect the exact position of the rotor. This paper presents design of BLDC motor drive. For the purpose of demonstration, the popularly used loads are considered for industrial application, electric traction system.
