There are a handful of motors that will work, with the Kollmorgen highest rated amongst them, but also hard to acquire and quite expensive by comparison.  The inexpensive options are the Chinese-made Mige motors.  The so-called “small Mige” has a lower power rating, so produces less force on the wheel.  If my experiments to date are any indication, that additional force is not needed.  😮

The “small Mige” is both quite heavy and quite powerful.


There is a compression fit coupling that provides the platform to which the wheel or quick release is attached.  The Simucube kit from SimRacing Bay included the 6-pointed star-shaped 70mm adaptor seen in the images.  The 4 bolts in the center clamp the coupling to the shaft.

But, since they stick out further than the surface of the 70mm adaptor plate, I needed to make a small spacer about 5/16 thick to prevent interference with my steering wheel mount.  Found some scrap wood and used a 3 1/4 and a 2 1/8 circular drill bits to create the spacer.
