| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 99 === This paper aims to develop the rotational speed independent
electric generator which is invented by our CCT laboratory. This
special electric generator is also called as the instant electric
generator and is patented by our CCT laboratory. The instant
electric generator is built in electric coil tube and a NdFeB
magnet is inside it for electric induction with motion of to and
fro. The outer two sides of the electric coil tube have two
movable NdFeB magnets which alternately moves close to the
electric coil tube and shoves the inner NdFeB magnet to run
through the electric coil. This action yields induced
electromotive force in the electric coil. This work mainly studies
working efficiency optimization of the instant electric generator.
The studied parameters are length, wire diameter, and turns of the
electric coil as well as weight of the inside NdFeB magnet. The
results show that the preliminary working efficiency of the
instant electric generator is ca. 42%. Moreover, this work
further made a prototype of ground electric generator using
instant electric generator. The prototype of ground electric
generator uses compression mechanism to pick up energy from
walkers and transports energy through integration of crank and
gear for stroke enlarging and electric generation. The
preliminarily reached working efficiency is ca. 5%. Finally, a
home-made automation measuring apparatus which uses Labview
integrate with the oscilloscope and the circuit design of
automation controlling load for determining I-V and P-V curves is
also successfully developed. The developed automation measuring
apparatus has helped to save investigating time and cost.
