Abstract
Nowadays, electric vehicles have become an important area because of air pollution, increasing use of renewable energy sources and being exhausted of oil fuels. In our country even the usage of electrical vehicles is not widespread nowadays, but also very popular and it is thought that it will increase. In this area, new studies and projects appear continuously Real systems are moving systems and it is difficult and expensive to evaluate by electrical vehicles; therefore an experiment mechanism has been created. In this study two fixed magnet synchronous hub motors have been used as wheels and the other one as load. In order to find the speed of the wheel, load value and coefficient of friction related to sliding, Burckhardt model has been used and the results obtained with different speed and road conditions have been presented here.
Highlights
NOWADAYS, productivity and saving of energy subjects have become very important because of pollution, decreasing amount of petroleum and energy problems
The structure of electrical vehicle is composed of inverter circuit which has been made up for power switching components, batteries group as energy storage part, control systems and mechanic power transmission system
Because the road load, which has been applied according to the road conditions, has changed, in order to find wheel speed and load value, Burckhardt Model [5] has been used for using the motors at the experimental mechanism, results reference values of the different speed and road condition have been shown
Summary
NOWADAYS, productivity and saving of energy subjects have become very important because of pollution, decreasing amount of petroleum and energy problems. Water and oil are very important energy resources. The most important problem is that oil is not an external energy resource and it will be exhausted in a short time [2]. Lead acid batteries have been improved in 1859 and their usage at the electrical vehicles have been become an important transition point [4]. The structure of electrical vehicle is composed of inverter circuit which has been made up for power switching components, batteries group as energy storage part, control systems and mechanic power transmission system. An experiment mechanism consisting by two hub motors has been designed in order to model electrical vehicles. Because the road load, which has been applied according to the road conditions, has changed, in order to find wheel speed and load value, Burckhardt Model [5] has been used for using the motors at the experimental mechanism, results reference values of the different speed and road condition have been shown
