small generator homemade using neodymyum sphere
« on: May 02, 2017, 01:31:44 PM »
small generator using neodymyum sphere 12.7 mm, 3,7 V baterry 600 mAh, small coil - turntable microwave motor, 3 V DC motor
https://www.youtube.com/watch?v=Y5p6oamAMZM
in the next movie we will try to obtain more energy using a 26 mm neodymyum sphere and more coils.

I observed that, when you are making a generator it is very important that, the stator ( the coil) to provide a total capture of the magnetic flux generated by the sphere.

In this video we are using 2 coils of 40 ohms each and a 30 mm diameter neodymium magnet sphere

in this movie I manage to light a 75 w bulb 230 V

I have tested the small generator layout  using a PWM controller for the 3 v Dc motor. Rotor : 13 mm diameter neodymium sphere. Coil : iron -less from a syncronous motor 230 V ( inside A4 laminator motor and microwaves turntable). The results :
