Use vibration to generate electricity

  • #1

Main Question or Discussion Point

Hello, I am a student making a generator.
the main idea is to use the vibration with the magnet coil setting with the spring to generate electricity.
I will use the permanent magnet, but i know that
e = N w B A
i decided to have a 12Volt output,
constant vibration frequency in 100Hz
the A is in circular,with diameter = 6cm(just roughly decide,can be change, but cant be too large)
but i didnt decide the number of coil (N) and the (B)
i hv no idea to choose how strong of the magnet should be.
or
may i ask that , in a resonable way, how lagre of the magnet i need to use to do this generator?

thankyou for your attention

The motion of the magnet relative to the vibrating mount is maximum when the resonant frequency of the spring (spring constant k) with mass m is tuned to the driving frequency of 100 Hz.
f0 = (1/2π) sqrt (k/m) = 100 Hz. See thumbnail.
