Scott, you did a great job illustrating the way voltages are varied to achieve different speeds for PSC motors.
One question. Would a weak capacitor cause a PSC motor to work on high speed setting (full voltage) but not on low speed setting?
Does a weak capacitor just not shift the phase as much as it should and thereby affect the running torque?
At lower speed there are lower rpms but does the torque remain the same? Would the current draw remain the same for all speeds while the voltage changes would be responsible for the horsepower changes throught the three speeds?
