Hello,
let's say I want to light a led (steady, not flashing) of some hundred
mW. I'd like to use a magnetic energy harvesting method, for example the
classical strong magnet into a coil (suggestion about other e.
harvesting method are welcome; no thermal or solar, though).
Given the following condition (estimated) for the magnet movements:
frequency of oscillation: 1 Hz
acceleration: 1 m/s^2
max velocity: 1 m/s
I want to estimate the dimension of the magnet and of the coil to
produce the needed energy. I bet they will quite large... but I need
just an order of magnitude.
Here another way to see the problem.
Given the coil:
length: 50 mm
internal diameter: 10 mm
# of turns: 300
wire diameter: 0,1 mm
and given the magnet:
material: neodymium
shape: cylinder
diameter: 10 mm
length: 10 mm
and given the information above about its movements, how much energy the
system could provide? I'm interested to a rough value: 10 uW, 100 uW, 1
mW, 10 mW etc...
Thanks in advance for any answer
