Hello all I’m new to the forum but am hoping some of you may be able to help me out.
This is not strictly EV related but hope what I learn from this will be of use to me when I start my EV project.
I wish to build my own dc brushless motor capable of spinning a mass (flywheel) of 6kg to 8000rpm, at which point the power with be cut and the stored rotational energy will be fed back through the motor to generate power to charge a small gadget (thinking my mobile)
Input power will be from a small PV solar panel whatever i can get cheap or diy 6V around 1A, and on the generating side I will need 5V @ 1A. This is to keep the output same as my phone charger.
I’ve now got the flywheel maths sorted and 6kg @ 8000rpm = 36000J or 2A or 10W (enough to charge 1400mAh phone)
I think I’ve settled on a motor design type but suggestions welcome. being of a brushless, radial flux, 3phase, hollow core, out runner with coil stator in-between twin magnetic rotors.
This is to be done on a budget and so I would like a pretty good idea of what’s involved before heading out and buy all the bits.
What I’m looking for is some direction in terms of number of coils and turns of wire to achieve the design output.
Hope someone can help and let me know if I’ve missed something.
Thanks
Ricky
