 As you say, this failure can't be solved by the rotor interface, whether in 
hardware or software. My installation uses "solid state relays" based on 
triacs. >>

Interesting, But the start or run winding would heatup in a locked rotor 
condition,I may install a safety heater (Bimetal) inseries with the triac. 
Which would have a cutout of
approx 15 seconds. Of course this would mean a manual reset to restart.
