jb Condensatoare Motor

Se folosesc condensatoare in motor deoarece motorul are sie el partile de circuite electrice iar condensatoare motor isi au si si isi gasesc locul in orice fel de circuit electric. 
Fiind niste dispozitive care stocheaza energia electrica, condensatoare in motor se gasesc in motorul electric.

Motorul electric foloseste puterea de condensatoare in motor pentru a porni un rotor. Fara condensatoare, motor nu ar avea pur si simplu puterea de a porni rotatia rotorului dar cu ajutorul acestor condensatoare motor poate sa porneasca si sa mentina rotorul in miscare.

Condensatoare de motor se pot schimba cu usurinta de catre un specilist, acestea sunt niste elemente pasive dar trbuiesc intretinute si verificate. 
Alte elemente pasive in afara de condensatoare motor sunt termistorii, manere, potentiometrele si rezistentele, printre acestea se regasesc bineinteles si condensatoare motor dar si cristalele de quart si filtr, bobine de inductie, varisori, filtre supresoare si bobine de protectie la supratensiuune. 

Cum spuneam, condensatoare motor sunt folosite pentru a porni un motor electric. Motorul electric monofazat are nevoie de condensatoare motor de pornire. 
Aceste condensatoare motor cresc cuplul de demarare al motorului, facand posibila pornirea motorului sub sarcina. 



Carcasa de la condensatoare motor este prevazuta cu un surub pentru montare si terminale sub forma unor conectori in general dubli. 
Pentru condensatoare motor sunt livrate separat si capace de protectie sau manere de montare, acestea sunt montate pe partea terminalelor iar alegerea de capace pentru condensatoare motor depinde de diametrul condensatoare motor.

jb Capacitors in Series with Mains & in Parallel

For capacitors in parallel

Capacitors in a parallel configuration each have the same applied voltage. Their capacitances add up. Charge is apportioned among them by size. Using the schematic diagram to visualize parallel plates, it is apparent that each capacitor contributes to the total surface area.

Several capacitors in parallel.

For capacitors in series

Connected in series, the schematic diagram reveals that the separation distance, not the plate area, adds up. The capacitors each store instantaneous charge build-up equal to that of every other capacitor in the series. The total voltage difference from end to end is apportioned to each capacitor according to the inverse of its capacitance.

Several capacitors in series.

The entire series acts as a capacitorsmaller than any of its components.

Capacitors are combined in series to achieve a higher working voltage, for example for smoothing a high voltage power supply. The voltage ratings, which are based on plate separation, add up. In such an application, several series connections may in turn be connected in parallel, forming a matrix. The goal is to maximize the energy storage utility of each capacitor without overloading it.

jb E3 & E6 Series Values

1.)Capacitors Breakdown voltage

Main article: Breakdown voltage

The breakdown voltage of the dielectric limits the power density of capacitors. For a particular dielectric, the breakdown voltage is proportional to the thickness of the dielectric.

If a manufacturer makes a new capacitor with the same dielectric as some old capacitor, but with half the thickness of the dielectric, the new capacitor has half the breakdown voltage of the old capacitor.

Because the plates are closer together, the manufacturer can put twice the parallel-plate area inside the new capacitor and still fit it in the same volume (capacitor size) as the old capacitor. Since the capacitance of a parallel-plate capacitor is given by: 

this new capacitor has 4 times the capacitance as the old capacitor.

Since the energy stored in a capacitor is given by: 

This new capacitor has the same maximum energy density as the old capacitor.

The energy density depends only on the dielectric. Making a few thick layers of dielectric (which can support a high voltage, but results in a low capacitance), or making many very thin layers of dielectric (which results in a low breakdown voltage, but a higher capacitance) has no effect on the energy density.

2.) Standard values

Before 1960 electronic components values were not standardised. The more common, but not the only, values for capacitors were 1.0, 1.5, 2.0, 3.0, 5.0, 6.0, and 8.0 as base numbers multiplied by some negative or positive power of ten. Values of 0.001 µF and above were stated in microfarads (µF, or often mF); lower values were stated in micro-microfarads (µµF, now called picofarads, pF).

In the late 1960s a standardized set of geometrically increasing preferred values was introduced. According to the number of values per decade, these were called the E3, E6, E12, etc. series

In many applications capacitors need not be specified to tight tolerance (they often need only to exceed a certain value); this is particularly true for electrolytic capacitors, which are often used for filtering and bypassing. Consequently capacitors, particularly electrolytics, often have a tolerance range of ±20% and need to be available only within E6 (or E3) series values.
