No, lossy is a capacitor term too. A perfect capacitor would have no
resistive losses at all. All of the energy you put into it via charging
would be delivered back to you on discharge. But real capacitors have
resistance as well, it absorbs some of the energy in the AC component of
the input, and causes the capacitor to heat up.
First, let me say that I am not an engineer, or electrician, or motor
repair person, but rather just a jack of all trades that plays with
things to figure them out so I cannot get technical for you here,
however, in the unlikely event that you still need this info, I have a
Craftsman 6 inch grinder that has the same capacitor and same
problem. I know that it is functioning as a starting capacitor since
I can give the wheel a spin by hand and turn it on and it will run all
day long, even after I have cut the capacitor totally out of the
system. Sears does sell them thru their parts section for 4.49 each
with a 6.99 shipping and handling charge plus any taxes for your area,
making the part cost 25% of a new grinder to me and the new ones have
a more powerful motor so I am also looking to find one cheaper
