Electric motor fault
<< < (3/3)
NormanV:
It was the on-off switch that I bypassed. It is  a no volt release switch so I wanted to eliminate that. The capacitor is 1.5uf and is always in circuit, there is no centrifugal switch. The motor does not have a rating plate. I checked the spec online and it is a 100w motor.
I am beginning to agree with you that the winding is gone. I will have to look out for another motor.

I would take it apart. Have a look inside. The windings will be solid copper, there is a joint where they are connected to the stranded wire to the connections. I have known these joints fail. No problem at all with the actual windings.
At least you can meter the windings for continuity.
Don't abandon hope 'til you sure no hope is left ...   :(
Best of luck ..  :zap:

I took it apart, it looks as though it is the end of the road for this motor. The windings are burnt.
Where can I find a cheap 100w motor? I thought about a sewing machine motor but the one that I checked
was 6000rpm, but I suppose that I could use the speed control. It might be quite useful on a scroll saw.
Any other ideas?
John Hill:
Norman, it looks like the connections are burned, not the coils themselves.  I suggest carefully cutting those 'cloth' sleeves off and looking at what is inside.  My guess is that you will find a poor connection which you will be able to repair.

NormanV:
YABBADABBADOO!!!!!!
John, I followed your suggestion and found a broken wire. I rejoined it and reassembled
the motor and now it is runnung at normal speed and with plenty of power.
Thank you those who made suggestions, I would have given up sooner without your help.
