Zelmer vacuum cleaner how to connect the soft start?
Vacuum Cleaner Model: missing - sticker torn off
Color of the vacuum cleaner: red
Engine model : S-690
Vacuum Cleaner Power: 1000W
Year of production: January 2006 (date stamped on the engine)

Sketch of the vacuum cleaner scheme:

Soft start cube:

In front of the anti-interference capacitor or behind?

Please help.

Hello. Ie. soft start of the engine very simply, connect the black one to the engine power cord
red for the switch together with the 2nd power cord for the motor with the switch and blue also for the power switch. And we plug in the capacitor together with the red and blue ones.

So I have to connect a soft start before or after the anti-interference capacitor?

I think so:

or yes:

Connect upstream of the anti-interference suppression capacitor.

so I should understand this:

EDIT:

Thank you for your help.

Added after 14 [minutes]:

And why did the mixer manufacturer connect like this ?:

I stole the photo from this topic: https://www.elektroda.pl/rtvforum/topic997208.html

schematic sketch:

after all, soft start is also made on a triac.

Here in this photo you have a speed controller so the manufacturer installed it.

but this regulator also sows interference?

Interference suppression capacitors
In systems generating disturbances related to fast surges of the consumed current (such as electric motors, magnetos, thyristor control systems), capacitors are filter elements limiting the penetration of disturbances into the power grid (see the quality of electricity) and the formation of radio interference. Interference suppression capacitors usually have low resistance and inductance of the leads as well as high breakdown voltage, they should allow the flow of current of high instantaneous value.

So in this mixer, the producer made a mistake by installing the regulator behind the filter?

There would be no electric saliva, a household appliance mixer creates disturbances in the power grid.

we don't understand each other?
I am returning once again to post 5

schematic sketch:

here the manufacturer will connect the anti-interference filter to the regulator

in my opinion, this anti-interference filter in the mixer should be connected before the PWM speed controller

Why so?

Because the noise is coming from the engine. And that's how it should be.

and the regulator on the triac or the soft start cube does not disturb the network?

So if I would connect a soft star in this way, it would also be good? (I'm asking out of curiosity)

Sory that I ask so many questions but I want to understand.

I think that the anti-interference capacitor will work before or after.

I think? so you are not sure about the advice given?

In that case, I will wait for comments from other users before assembling the vacuum cleaner.

Topic summary

The discussion revolves around connecting a soft start mechanism to a Zelmer vacuum cleaner with a commutator motor (model S-690, 1000W, produced in January 2006). The user seeks guidance on whether to connect the soft start before or after the anti-interference capacitor. Responses indicate that the soft start should be connected upstream of the capacitor to minimize electrical interference. The conversation also touches on the implications of connecting speed controllers and interference suppression capacitors in relation to motor noise and electrical disturbances.
