Chuo Seiki AMH-13
I picked up a X stage which uses a Chuo Seiki AMH-13 auto micro. The auto micro uses a coreless DC motor and of course came without a driver.
It turned out to be pretty simple to drive, requiring only a DC voltage somewhere in the region of 1 and 5V. When I was testing it I set the current limit to 200mA and it appeared to consume between 100 and 200mA.
