Marius, the spindle motor in question is going to be a beast , as it's really a servo motor and Tacho , and may well have brake also these tend to crazy to work with , as you'll also need to be able to not only hold positon and zero crossing switches etc you need to monitor each leg and phase . amo

I have only worked with IGBT/MOSFET and expected solid state relays to be slow devices not suitable for PWM but they say "12 - 20kHz FAST PWM speeds". They state it is solid state relays but the figure on the top is an IGBT which require a good driver and electrical isolation! Nicklas Karlsson

I need to run the motor to its top RPM. Thanks, Andy, but I doubt this one will be enough. And even if it is - I think it's overcomplicated solution. Quite expensive too. I am planing to retrofit 2-4 machines. What do you think about controlling DC SSR with PWM like HDD-9V30E from http://www.po
