Re: [TCML] rotary spark gap motors

Miles,

Hysteresis sync motors do not have salient pole properties.  Yes, using a
hysteresis sync motor you'd have to re-phase the spark gap every time you start it up.

I show some sync rotary gaps at my website at:

Trying to figure out the right motor type to run an SRSG with NSTs..  I know I 
want a synchronous motor and I have read that it should be a salient pole type.  
So my questions are;
Is a synchronous motor with 4 poles with an RPM of 1800 a salient pole? Or 6 
poles at 1200 RPM, etc... Or just a synchronous motor?
If the motor is just synchronous without salient pole properties, does this mean 
I have to "re-sync" the spark gap every time the motor starts? Do Hysteresis 
Synchronous Motors have salient pole properties?
