Wiper motor mod

[Dave Lane]

So the Singers wiper motor was making strange noises and this was tracked down to a worn armature shaft .
No probs as we might have some at work and after much hunting found a S/H one with a near perfect shaft , winding was shot thats no issue .
Also they have been a tad slow , wether due to the shaft wear or something else im not sure however every test I did came up with nothing , no stiff wheelboxes or cable , voltage fine etc etc .
Anyway as the armature needed a rewind and having got the original winding spec I altered it in the hope of more speed .
And it worked - almost too well ?, nice to have decent wipers at last
One very worn Shaft , ----------------------------------------------------------------- its replacement was perfect ,this image is after the rewind obviously


Comm turned and undercut Tother end , known as the Comm end -------------------------------------And this is the back end


End Result



As they were on the old armature , this is engine off. rather slow to say the least

Much Better , same as above , engine off - background noise is my neighbour who decided just then to pressure wash his car

And end result, sorted !

Nice job Dave, must be so handy being able to do motors like this.

How many speeds do the wipers have?

Just the one , yeh real handy being able to do this , no one else can in the club AFAIK

Just the one ,

My MK1 has two speed wipers on it which I find really handy.



Speeds are.............................. Off & On
The old ones are the best.

No one else I can think of, I know where to send any motors we need fixed now.

Your a magician Dave, Pat, the winding was done at 10V so -2 from where it would be at rest. So was thinking boost converter and do 14V at rest (12>14V boost)

Should be same effect. My worry is that Daves biggest upgrade is the removal of the 50 year old shellac or varnish and a nice new coat of insulation and baked.

Damn fine mod though and Dave would be the only one that could do it.

Dave has the winding details Pat if you fancy re-winding one ?

Thank you , yeh ive got the winding spec if anyone wants to have a go Lucas never even varnished the windings , its loose in the armature . Its done on the cheap really . i use top spec insulation , double coated wire , slots are pegged in and the varnish sets the windings solid - its cooked for 10 hours after its been soaking in it for a day and left to drain off .

Pat might have a go, that sounds like voodoo to me plus my winding leaves a lot to be desired
