Possibly a decoupling capacitor. You connect these to a signal line down to ground. Capacitors have a 'resistance' that is inversely proportional to the frequency of the voltage. So to a DC voltage the capacitor looks like an infinite resistance or open circuit. But if there is any noise on the line that will have a frequency so the capacitor will look like a resistance, the higher the frequency the lower the resistance. The idea is to make the capacitor look like a zero resistance or short to ground to any interference but an open circuit to any DC component - so it removes the noise. They are often added 'just in case; and this is why circuits will work without them. In the worse case you might have a bit of noise on the signal but unlikely to cause any issues - more of a concern with audio/visual circuitry.

Often referred to as a filter cap. Typically used on a dc circuit to remove any stray AC signals by shorting it to ground. 👍 I can't see the traces well enough on the video, but It's very likely.

An opto-isolator separates two parts of a circuit with an air gap. So rather than have a wire joining the points on the circuit, one point drives an LED and the other side as a photo-diode. So you can pass a signal between the two even though there is a physical gap inside the chip - the two points are not electrically connected together. A typical use is where you want a digital connection between a part of a circuit operating at a high voltage with another part of the circuit which is running at a low voltage. So you form a digital connection across the airgap in the chip with light and there is no chance of dangerous high voltages getting across and damaging sensitive components on the other side.

That is the fun thing with capacitance you can take the capacitor out and still have a capacitance reading. So taking it out fixed. This can happen as well. When I did my electrical courses in the 1990s if the insulation resistance less than 0.5 Mohms or 500000 Kohms then you had to fail it it could allowing electricity to flow. But then we were also putting 500Volts through the wires. So the reading he was saying seem a bit low for a capacitor since both sides of a Capacitor should not be connected at all. This is why a Capacitor symbol is 2 lines. I was told in electronics at College that if they ever discover a substance that could not conduct electricity then we would have capacitors that would never discharge.

That CAP was likely leaking, and that type of cap is call MLCC based on the color of it. You'll find that cap next time you sweep the floor, if you remember to look for it. Too bad that type of cap never tells you what there value is... before they run away and hide. 🤣

Well done. Would depend on where the capacitor was connected, if on the input (diode) side then basic switching protection for the micro, if on the output side then part of a snubber (protect the motor and internal triac from spikes) which usually has a resistor in series. Slightly odd use of the MC3083 if it is controlling the motor directly, there is usually an external triac or SCR. Either way (as others suggest) refit a capacitor.

It's a matter of design philosophy for making something high end. Does one implement features with simple components, iterating and tweaking the design, taking longer to get it "just right", but keeping the naked parts cost low, or does one go the programmable logic route where the hardware is basically set in stone at the beginning and the software goes through the iterations to get it "working right". That's more expensive to produce per item, but it drastically reduces one's "time to market". Dyson chooses to have one hardware implementation and then implement its various devices in software, because recently graduated programmers are cheaper than experienced hardware engineers. It's a choice.

@natsterjam Ай бұрын

As someone already mentioned, if something turns on when it shouldn't, it's often a shorted MOSFET. When they die, they permanently turn on. Optocouplers are usually used to pass information back to high-voltage side and it's unlikely that's the culprit here. That capacitor might have been leaking a bit of current, MOSFETs don't need much to turn on, they just need to "see" voltage. That's the only explanation I can think of.

Result! It works with one less part. That capacitor should show as an open circuit on a 'Multimmiter'. Opto isolators are used in a feedback loop, for control of a mains power supply. Those caps are famous for going leaky, or short completely. The oscillator motor looks like it had three wires, so possibly three phase AC. That leaky cap possibly fired up the power supply, when it shouldn't have.

To vastly oversimplify, resistors let DC through, good capacitors do not. As the capacitor you found had got a large-ish resistance it was likely letting DC through where it should not have gone - which happened to turn the oscillate motor on. The cap was there for a reason, so you really ought to put a new one back in its place or bits of the circuit could suffer over time. Hope this helps?

The capacitor is just filtering any noise off so the LED in the opto-coupler I.C. won't accidentally turn on. Try radiating some RF noise close to the device, like a mobile phone or microwave oven, and you might see the device jitter and make a ghostly move as the noise introduces enough DC voltage to light up the internal LED. The opto couple is typically used to isolate the 240 volt side from the low voltage (e.g. 12 volt) side. When the LED is lit up (inside the opto coupler) an opto receiver on the opposite side of the opto coupler chip sees the light and switches on a transistor type component to conduct the 12 volts to the motor. This mitigates the risk of any high voltage shorts producing 240 volt on the 12 volt side and potentially killing someone or causing a fire. Not having the capacitor is not likely to cause any noticeable effect in a low RF noise environment. Personally I would have just disconnected the oscillator motor and told the customer it's buggered, but you can still use it to blow straight - but I'm lazy.
