Don't they just throw juice to windings in both directions at once,
essentially freezing up the motor magnetically? That's a little safer

On a bunch of my 3-phase machines, I used what is called a plugging
switch that was controlled with a V-belt coming off a main shaft to stop
the motor.


Huh? How does a switch (electrical) controlled by a belt (mechanical)
stop a motor (electrical)? Ya lost me there, Tawmmy me boy. Are you
running a steam engine and mainshaft in yer shoppe?

Zis you? http://tinyurl.com/o2lctvz
