| Summary: | This report presents the designs of linear generators which can be applied into the road bump of UTP. Universiti Teknologi PETRONAS consists of more than 1000 cars and it should be able to apply a force on the linear generator while car crossing the bump. The linear generator is able to produce electricity when a force is applied to it. In the report, literature review of the linear machine topology is included. Four types of linear machine are discussed in the report and two designs of suitable linear generator are proposed. The designs are set based on few criteria which are simplicity, performance and suitability to be used in the road bump. The parameters of the proposed designs are included and it is set according to the standard size of a road bump so that it is able to be fitted perfectly into the road bump. Finite Element Analysis method is applied to simulate and analyze the result by using ANSYS software. The results of both designs are included whereby comparisons have been made in terms of air gap flux density that is taken in air gap of the machine and also the induced EMF. Besides, optimization work has been carried out in order to obtain the maximum magnetic flux and also optimized design whereby maximum EMF can be induced. Three areas have been optimized where maximum magnetic flux can be obtained, balanced between electrical loading and magnetic loading and also balanced between copper loss and iron loss. The results of both designs about the magnetic flux in the stator and air gap flux are discussed. Furthermore, a comparison on both designs is included as well. The air gap flux induced in the linear generator is discussed and graphs are included. In conclusion, a decision has been made to decide which design should be chosen and applied in the road bump in order to increase the performance of the road bump application to generate electricity. |
