I have been following the posts concerning the design of SRSG phase
controllers. One of the major concerns, at least for larger motors, appears to
be the self-breaking action of the motor upon spin down. Could this not be
prevented through the use of a double-pole switch to completely remove the
phase control circuitry from the motor when it is turned off? One of the switch
poles would break the circuit from the 120 volt power while the other switch
pole would simultaneously break the circuit from the phase controller to the
motor. This would prevent any self-breaking action. Comments?
