Too large capacity of the capacitor for the 230V motor, is it possible

I would like to know if it is possible to use a 20µF capacitor for the motor
which worked with a 16µF capacitor and ran at high speed?

In the absence of a 16µF capacitor, I would like to use 20µF.



Below are some photos.

Hi. Nothing will happen instead of 16µF you can successfully use 20µF I did it. Rather less of a problem. The motor has trouble starting under load.

So it will not change the speed and power of the engine

Hi. Neither power nor speed will change. And even under load, the engine can start more confidently.

Thanks for your help, but there is one more problem, it doesn't spin. And when it starts to run at idle without a capacitor, the light goes out and the plugs burn out. I connected it as the diagram says and nothing but buzzes, even if you manually accelerate it, it doesn't spin. so I plugged it in different ways and nothing better but the traffic jams sit down.

Is the engine damaged?

Why in different ways? Not cheaper right? Do you think isolation will wait?

It is not worth exaggerating with the capacitor, because when it is too large, the motor will start to heat up, and as for the fact that it does not want to work properly, it is necessary to check whether it has good windings because after such tests it is not known

Hello, the inscriptions suggest that it is a tamata or a wiaty (washing machine) engine. If so, this engine is basically useless: the mower is too weak, you can buy a grinder in a supermarket for funny money and with a disc holder on both sides (and a capacitor) I would start the topic with what it is supposed to be used for? Colleagues are right about the capacitance of the capacitor: the larger it is, the more current flows through the auxiliary winding and it is made of thinner wire, and in extreme cases it can cause burning. +- 30% will not damage it, but in some applications it will either not move -30% or it will heat up +30%. Calling it (in the case of burning it does not pay: for scrap metal for PLN 5 you can get another one, read in good working order.

I agree with colcolcol, this engine is not worth interest if, according to what was written about it, it is burnt because, as stated, it did not work according to the scheme, it is better to buy another efficient one

The engine is from the shed. It's supposed to drive a slow-speed sharpener. such a razor costs from 1500 to 2300 although it has a simple design.

So the engine for scrap and I have to look for a new one?

Well, from what I read, if it doesn't work when it's connected according to the diagram, normally the motor should accelerate after turning it by hand - when it's good (after giving it the direction of rotation), it's normal operation of the motors.
If this one does not behave like this, and after connecting the capacitor it also does not spin, then the conclusion is simple, it's time to wind up, because there is nothing to try if it won't help anyway, it's a waste of time.

Every motor (!) from the washing machine, the so-called compact (brushless) can be used for your device, it is very difficult to burn it even through wrong connection, unless it is damp or has worn insulation, each (!) of this type of motor has 16 or 12 pairs of poles used for spinning "slowly", if a large (about 8 cm) pulley is installed, the pulley itself can be replaced. but these engines are in Bydgoszcz at the first better scrap yard from the subway. When connected, it should draw about 1 ampere without load until .. not much more.
