[TCML] SRSG talk continued... If you build SRSG's, this is a must see!

Well first off I finally found a few answers to my own questions online. 
Yes, an 60, 1200, or 1800 (etc) rpm motor is called synchronous because 
of its rpm value, but... there are other traits, a sub category if you 
will of synchronous motors. This is so stupid, because I feel everybody 
has been trying to tell me this...   :-[  The sailent pole is a type of 
sync motor that will always lock phase in the same position regardless 
how and when power is applied. I knew all this. I think it was just a 
matter of sorting out what was what and why the motor behaved this way.

Essentially, it sounds like a hysteresis sync motor is one which 
operates very quietly and in perfect sync with AC waveform but starts up 
in a random position each time where as the salient pole sync motor 
concentrates the flux lines through the armature allowing the motor to 
maintain a position with respect to its stator when power is applied, 
but it does so sacrificing added noise, and vibration.

Ok sorry, now for the website everyone MUST visit:

Not sure how much these babies will cost but its worth a phone call next 
week.
