RE: am I a SRSG failure?

Hi Dave,

Do you have a clamp on ammeter? You should be able to notice an increase in
amp draw after milling the flats. You will want to get to just under the
rated full load amps with rotor and electrodes installed at rated voltage. I
don't look for dead poles or anything, just take a little off, try the
motor, take a little more, etc till I can get lock up at near half rated
voltage with the rotor installed. Yes it is a lot of work to take the motor
apart and put it together several times, but in the end it is the best way
of getting close to optimum performance out of a motor modified for SRSG
duty. The best set of tool to tackle the job are a variac, a voltmeter, and
an ammeter. Of course a milling machine doesn't hurt, but elbow grease,
persistence, and a grinder or a good sharp flat file will work just fine.
