Hard to say Phil without some kind of manual- can you post a close up of the terminal block?

.any ideas what motors I can [power?] with these
what I gather from this manual is that the drive is singular purpose designed for a very specific piezo-electric vibrator. Not a rotary motor.
If you could track down one of these Sanki piezos maybe you could make an unnecessarily complicated sex toy.
Otherwise I'd call it useless.

The timer might be useful for someone building a RPC to drop out a starting contactor possibly, but the controller like Strantor says won't be too useful.

Even the 200mA versions, if they have the same phase and frequency specs (single phase, 60-300hz output) are not going to be useful for powering any kind of A.C. motor whatsoever, except for the piezo units from Sanki. These are very niche drives for a very specific application and might be worth a lot of money to someone with a Sanki vibrator looking for repair parts. If I were you I would put them on eBay for a high price and wait wait wait for the big fish to come along. You may have to relist several times.

In the mean time those fincor drives are probably your best bet. Old but good. Of course you would need to verify the specs on those meet your requirements.
