Can't read the Tr4 picture, better focused pics please.

 

Can't read the Tr4 picture, better focused pics please.

Surface of Tr4 is VERY shiny and stamped? details very small, seems to be something like
E828 5144
R5P212A7NPA
The twopin connector nearest and below is marked RXD1
TXD1
Sorry not able to give you more info. Have att another photo in case it may help.
Thanks again fo help

Connected per your suggestion but it won't run. Do I need a ground (earth) connection too, and what about the temperature sensor?
Grateful for your help,
Ray

Just read this about Beko (origin of the motor). Could this motor be of the inverter type, and what difference does that make?
"
What is ProSmart™ Inverter Motor technology?
Our ProSmart™ Inverter Motor technology comes with some of our washing machines, washer dryers and dishwashers. This type of motor is brushless which helps to drive its high energy efficiency and its ability to rotate at optimal speeds, which means that the overall efficiency that your appliance runs at will increase. That it’s brushless will help to reduce the motor’s friction, helping it to be quieter while it operates
Best wishes,

Okay so can you measure the resistance of the field windings, M1,M5,M10, and does it definitely have two brushes on the rotor, if so you can test it by measuring the resistance across the brushes and spinning it, the reading should go up and down.

Sorry to ask such a silly question but do I measure field windings as M1 to M5 or M1. to earth?

 

M1 to M5 and M1 to M10,

 

M1 to M5 1.5 ohms, M1 to 1.7 ohms. Motor definitely has two brushes and resistance across them goes up and down on spinning.
I'm obviously doing something wrong - why can't I make it run?

 

Looks like you do have the older Brushed, Universal? motor.

 

I think this is the motor., put one field winding in series with the brushes for one direction, and the other field winding for reverse.

Thanks for both your replies. The videos from MaxH did indeed show me how to get the brushes out, and back in but I don't think it told me much else. Dodgdave's video went deeper, but sadly relied on English subtitles to a commentary in. I think, Hindustani.
Some useful diagrams there but I'll have to look again tomorrow to see if I really understand what is being explained.
Thanks again for help from both.

It is a series motor so the fields and armature are in series across the controlled supply.
Universal version, works on both AC and DC.

So just put one field winding in series with the brushes and it will run one way. The other winding is for reverse.

 

With a Universal, series field motor, you need both field windings in order to run, both windings have to be reversed in conjunction with the armature.
To reverse, either swap leads to both fields or the armature.
Shunt field motor , the same thing.

Normally yes, but this one uses one field winding for each direction . See video previous post#30.

 

Seems a very hard way around reversing a Universal motor!!?
Tracing the motor schematic out, deciphering the video, they appear to have wound two sets of field windings, and each is selected for each direction.
Rather than just reversing a single N.S. pair!

Yes i know, i wondered why it had a tapped field winding, and now we know.

 

So just put one field winding in series with the brushes and it will run one way. The other winding is for reverse.

Many thanks, now have it sorted.

Good, so how did you wire it , like the video?
