Design of Tubular Permanent Magnet Generators for Vehicle Energy Harvesting by Means of Social Network Optimization

In this study, we report a multimodal energy harvesting device that combines electromagnetic and piezoelectric energy harvesting mechanism. The device consists of piezoelectric crystals bonded to a cantilever beam. The tip of the cantilever beam has an attached permanent magnet which, oscillates within a stationary coil fixed to the top of the package. The permanent magnet serves two purpose (i) acts as a tip mass for the cantilever beam and lowers the resonance frequency, and (ii) acts as a core which oscillates between the inductive coils resulting in electric current generation through Faraday's effect. Thus, this design combines the energy harvesting from two different mechanisms, piezoelectric and electromagnetic, on the same platform. The prototype system was optimized using the finite element software, ANSYS, to find the resonance frequency and stress distribution. The power generated from the fabricated prototype was found to be 0.25 W using the electromagnetic mechanism and 0.25 mW using the piezoelectric mechanism at 35 g acceleration and 20 Hz frequency.

The Impact

The amount of waste can be overcome, some efforts are needed to reduce it. This research will focus on the numerical model of a solid waste power plant. Researchers replace turbine with an impact which have a specification certain pressure, the impact rotates the generator The purpose of this research is to get the rms voltage of a generator, where the generator is a generator capable of supplying a rms voltage. This effort is made to convert waste energy into electrical energy. Generators which are the main topic in this research are synchronous generators and permanent magnet generators.
