Electrical filters for sewing machines - why?
Greetings everyone - today we're going to talk about electrical filters, why they're needed, how they work, and what's being sold...
Important note! Everything written below is for people unfamiliar with Ohm's law, simply for users of household machines!
If you own an electromechanical machine - then this topic is not for you :)
V In electromechanics - power fluctuations in the network can affect the machine's operation very rarely - in 99% of cases you won't notice it :) unless you're sewing during a thunderstorm and there are voltage surges in the network at that time, then yes, the machine will slow down or speed up on its own.

And for computer machines, good power supply is sometimes critical.

EThere are several elements in the machine that can be affected by static and power surges. First of all, the touch screen (settings get messed up), and in some machines there are also touch control buttons, which are also susceptible to false triggering from static or interference in the network.

SStatic electricity - we all remember the physics experiments with a glass rod, a sphere, and wool :)

PWe can get approximately this when working on the machine if certain conditions coincide. For example, cold, and working with wool...

NNetwork voltage instability. This also happens - different houses, different wiring, even if you did everything "according to feng shui" in your apartment/house - your neighbor could have done it completely differently, or just decided to use electric welding. The load in the network will cause a voltage change - and in which direction, only a fortune teller knows :)

Ht's good if it's low, then everything will be fine, but if the voltage rises, trouble is inevitable, and the circuit breaker will not save, because it works by current, not by voltage.
BMost household machines do not have grounding (a plug with 3 pins), and our homes, with very few exceptions, also do not have grounding in the network.

ISometimes this leads to changes in the touchscreen settings (controlling the machine by touching the display), sometimes the machine can spontaneously start sewing slowly...

InOf course, you always need to understand the specific case, and there can be many reasons for such behavior – but poor power supply is one of the possible ones and cannot be ruled out.

What to do?

YIs the machine behaving strangely?
EIf possible, take it to friends who live further away, not in your area, sew there – if the problems are gone, then a voltage stabilizer will most likely help.

I About it, actually.

WOften in chain stores, a power strip and a stabilizer are simply called an extension cord. NIt has nothing in common with a stabilizer.

SA stabilizer has components in its structure that allow it to maintain a constant output voltage within a certain range. It can also disconnect power to the connected device to preserve its functionality if voltage limits are exceeded.

NFor example, during imbalances and surges in both directions during a thunderstorm, in abnormal network situations, etc.
InAs a rule, they are publicly known as voltage stabilizers for gas boilers. It so happened that this particular area is critical to power, and no one wants to "joke" with gas :)

Pfuses that are in the devices - protect the external network, that is, your wiring - and in case of a short circuit, the "fuses will blow" and the circuit breaker will trip.
But a fuse cannot protect against a power surge!

"Fuses" - the circuit breaker will only trip by current

EIf your home network does not have a voltage protection device, then the most expensive equipment for you should be used through a stabilizer.

InOf course, you can't get enough stabilizers for all consumers in the house - and that's a completely different story :)

VThe photo above is just an example - you can easily find a suitable option by searching for "voltage stabilizer".

OPay attention to its output power - 150-200 wt will be enough for most machines.

EIf you need advice on selecting equipment or related issues, I'm always happy to help!
