3phase control circuit

[mares]

Hi All,
Who can advise me a simple circuit for 3phase (variable freq) control? I am looking for a circuit what gives me 3 outputs (120-120deg shifted). The uotputs can be ttl or any pulse (at zero crossing fe) and the input can be an external pulse (clock) source or any control signal determining the frequency. I think there can be an IC or set (but not microcontroller solution!) I hope some of you can help!TIA (thnx in advance)

I can't think of any specific parts of the top of my head but there are heaps of ICs out there for driving 3 phase model engines. In particular brushless motors for model aircraft.
