An electric rake is designed for removing thatch from lawns - I think that ivy stems would just clog the tines.
A rotavator is a big heavy thing and far more awkward to use than a fork, and you'd have to go over and remove all the ivy by hand anyway after it had been churned up.
Sorry, I know it's not what you want to hear, but I don't think there's an alternative to digging methodically with a border fork and pulling the roots out by hand - that's how we got rid of ivy from the beds and borders in this garden.
Good luck - it's cheaper than gym membership and it's out there in the fresh air with the birds - at the moment every time we turn a forkful of soil we're joined by a robin who is feeding his hungry family on the grubs and worms we uncover
