I am building a kind of torque converter exercise machine that I invented and I would like to add the ability to generate power. I''ve got a 100mm rotor 30mm wide spinning at between 1000 and 5000 rpm with Neodymium magnets pointing outward radially. I would like to generate 3+ volts at 1 to 5 amp to charge lithium batteries.
Furthermore, different magnetic loads may require different amounts of capacitors to be used, and the system should only use as many capacitors as needed. Power transistors controlled by a micro controller will be used to coordinate the charging and discharging process.
In the past, creating permanent magnets in labs involved unsafe high energy sources, such as arrays of lead-acid batteries. The goal of this project is to develop a capacitor-based system capable of creating magnets using much lower levels of stored energy, resulting in a safer in-house production process.

The best magnets for generating electricity are neodymium, ceramic, and alnico magnets. These types of magnetic materials offer high performance and cost-effectiveness. To increase the efficiency of magnetic generators, consider the size, shape, and grade of the magnets used. Can You Generate Electricity at Home With Magnetic Field?
To connect the permanent magnet generator to a power source, follow these steps for a safe and efficient operation: Power Conversion: Connect the generator to a power inverter to convert the generated energy into usable electricity.
Using capacitors instead of batteries as the energy store will result in lower total amounts of stored energy, thus improving the safety of the system. Since the system will be designed with the intention of magnetizing only a few magnets at a time, it will be well suited to making custom magnets cheaply.

You might want to put in a battery to smooth out most of the peaks and toughs, and the capacitor to smooth out the little bit of surging at higher speeds. Otherwise the capacitor will have to be a pretty large size. You will only be able to put in one generator due to the difficulty in syncing the phases. Some diodes could be used to ...

So to reduce noise, some small ceramic capacitor are mandatory, usually 10 to 100 nF (between pole or pole to ground or both). You could also add a common-mode choke and even use an EMI filter. . If the ac component is too high and affect the powered energy converter, adding another big capacitor and a dc motor choke (or dc reactor) could help.

$begingroup$ The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully …
converter power and circuit type (topology) versus core sizes and gives some useful thermal resistance values for ferrites. Manufacturers give rules of thumb of 5 W to 15 W of conversion power per cm3 for most core shapes (and 30 W/cm3 for toroids). This can be used in a computer program for choosing a core, though it is somewhat crude.
Permanent magnet generators offer several advantages over traditional generators. These include increased efficiency, reduced operational noise, and decreased size and weight for the same output power. The efficiency gains are particularly significant because the PMGs do not require any external power source for magnetization, reducing energy loss.
We propose an innovative floating capacitor method to produce a high output voltage and suppress the power variation with capacitor energy storage for addressing these concerns. …
When designing the structure of your generator, it''s crucial to consider the size and weight of the permanent magnets. Proper spacing and alignment of the magnets are essential for efficient power generation. You should also focus on using a sturdy frame and housing that can support the magnets and withstand the rotational forces.

Ceramic Capacitors. The most commonly used and produced capacitor out there is the ceramic capacitor. The name comes from the material from which their dielectric is made.

In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the heart—called cardiac or ...
We propose an innovative floating capacitor method to produce a high output voltage and suppress the power variation with capacitor energy storage for addressing these concerns. Nevertheless, the driving power supply used with this method needs to establish control of the floating capacitor voltage.
There is, though, a very big disadvantage in skin effect. Only a small amount of a conductor''s cross section is available for use. Therefore, only if the conductors of mag loop are large can they be efficient. The next optimization factor will make this very plain. No other building material, therefore, compares to PVC pipe and self-adhesive metal foil tape for optimizing a mag loop ...

Most Permanent Magnet (PM) motors have power factors in the range of 0.70 - 0.95 so you can see from the plot above that maximum capacitor current in this power factor range occurs when the modulation index is somewhere between 0.6-0.75. The capacitor current will be 0.55-0.65 x the phase current for PM motors with these power factors.
