My new band saw has a three phase 3 HP motor. The magnetic switch is
broken (the saw runs fine if I bypass the switch).
I can't find a source of three phase magnetic switches. Anyone have one
to sell, or can offer a commercial source (no luck on ebay for a week)
Betcha Grainger or McMaster-Carr has them as well. MiniMax also sells
3phase machines, betcha they also could supply a switch
However, BEST folks for a new switch that will FIT would be the folks
who made/sold the saw, have you contacted them???
You need a magnetic motor starter complete with a start/stop switch.
NEMA size 0 will do the job.
Any decent industrial electrical distributor can help you.
BTW, you need the FLA shown on the nameplate to select the correct overload
Don't be shocked at a $200 price tag, it will be within 20% of that.
Your having a jargon problem -- it is refered to as a motor starter
instead of a motor switch, and I just did a quick search on e-bay and
there are a bunch otherwise Grainger has 'em but ouch their expensive
Check to see if your present motor starter has a replacable coil. If so they
are generally removed by taking out a couple of screws off the cover. Check
the resistance of the coil and if it's open get a new one. Cheaper than a
whole starter. Keep track of the relationship of any parts that come out with
the coil (iron laminations)
