What is Starting capacitor

A starting capacitor is a capacitor, which supports a motor at start. So far so great. However what if the starting capacitor not anymore brings his performance and for the engine merely by a shove?

An exchange is somewhat simple, considering that a capacitor is inserted through either a cable or soldered. Plus or minus does not exist. Care must be taken that this newly purchased starting capacitor actually has the same power = microfarads. A deviation of 10% is controlable, it is usually critical. If the value is no more legible, you have got a problem, simply because the significance is not ausmessbar. You could possibly ask the manufacturer, that has been installed.

Essentially, the start capacitor in contrast to the run capacitor only once the engine help via phase shift. Because the load is at its highest here, starting capacitors are used only for relatively strong engines and help them to start. They are then switched off ... otherwise you wouldn't survive long. Particularly in compressors and floor grinding machines, this is the case.

The capacitor (marked with DB for continuous operation) can be used as a starting and running capacitor, as he endures more and is designed for continuous use (10,000 hours).

In the event that two capacitors are present, one is thus the starting capacitor, the opposite of the run capacitor. If perhaps one is present, you absolutely need a long term capacitor! Simply install any starting capacitor that would actually be a short pleasure.

Unfortunately, there stand it cheap and simple electrolytic capacitors, which can be thinner and thus less twisted. One can only recommend to always select the actual thicker foil capacitor - costs only slightly more, it continues much longer.
