Hi I'm hoping you can help me save a much loved and needed powertool for which spares are no longer avaiable.
The tool is a combined mitre and table saw.
It has had little use but just wouldn't work after giving absolutely no reason to suspect a problem
We checked for basic continuity,re-made the internal connections to the switch upon which the saw started but would not shut off.
There is a speed control module together with a speed sensor ( Hall sensor?)
The only reason we can think of for the speed control is for a slow start which we really don't need.
Spares are unavailable and a replacement is several hundred pounds.
We are thinking the motor field and armature windings are sound,I guess these are checkable though? so were wondering if we could rewire the switch arrangement without the speed control.
So we're looking for a wiring diagram to connect the motor to the switch including the capacitor.
From reading posts on here it will be a universal motor I think,and the capacitor present is for suppression/reducing arcing at the commutator.
Hope you can help.
p.s. I have a decent understanding of basic electrical theory,and own a good quality meter.
Thanks.
Mick.
