How to make a reversal of an induction motor through a NVG button

Performing an audit of the shed, I found an old motor from a washing machine, start up from the relay PNVS 10. Convinced of the engine serviceability and relays, I decided to give them a second life in the form of the winepress, with the possibility of reversal. In this article we consider the reverse circuit and collect it in practice.

Engine Checking and preparation of material

Before starting the assembly of the circuit is necessary to conduct a full review of all parts of the engine, which mark AEP 16UHL4 220V 180WAnd make sure that no backlash and bearing performance. Also, if there is no terminal markings of the motor windings, it is necessary to determine in advance what the ends are starting coil and what to labor.

For this we need a multimeter and 4 marker tags.

So, we turn on our multimeter on a dial, take two arbitrary end and measure the resistance. If the device shows "1" - this means we've got different ends of the windings, so just replace one of the ends and then make the measurement.

So, I got that one winding resistance 16.5 OhmAnd the other 34.4 Ohm. Winding with less resistance - Working, and with a large - launcher. Now it is necessary to mark the findings according to receiving guests and all, the engine is prepared.

After that the button will need to prepare PNVS (Starter push), the switching switch (two or three positions) and connecting wires.

Note. I am well aware that this button - a rarity, and now reverse the scheme collected on starters, but it is possible in many such details lie idle. And after reading this article, they will be able to use them again, that is, bring them a second life for a long time useless things. So, experts and fans of new gadgets, do not judge strictly.

After all is prepared you can begin to reverse the assembly according to this scheme:

Wherein one terminal of the operating winding is connected to terminals "1" starter, and a second terminal connected to the contacts through the actuator output toggle number 5.

Conclusions start winding connected to pin tumbler 3 and 6.

In this case, we do the jumper between the contacts of toggle switches 1-6 and 3-4.

All our run scheme with the possibility of reversing completely ready. Now you only apply 230 volts and experience gathered on the performance scheme.

If you have neither the desire nor the ability to change the connection scheme and add a toggle switch, the change the direction of rotation of the connected motor is easy, just simply change the conclusions of one of the windings places.

conclusion

That's all I wanted to tell you about the reverse pattern beskondensatornogo single-phase motor with the start of the relay. If the article is to provide you with interesting and useful, do not forget to rate her huskies and thank you for your valuable attention!
