This motor will work very well for use with an inverter, the advantage of a 6P is greater torque vs. 4P. The usable speed range would probably be something like 20-100Hz. A fan cooled motor may tend to overheat if used too long below around 20Hz.This is the motor i am thinking of for my lathe.

Uncle Harry, I often suggest that individuals remove the stock control board completely and store it away if there is the intent to restore the machine to stock at some point. It i s much simpler to design a basic VFD control system with a couple of relays and a power supply, or a single relay and no power supply with the WJ200 that will work better and safer. Having contactors to switch motor directions and break power to the motor with the VFD operating could damage the VFD and defeats things like motor braking. If the the stock contactor have an unused NO pole (or configure one of the L1-L3 poles) one could use this to control the VFD input direction and retain the stock system wiring, the VFD would directly connected to the motor. As mentioned, used contractors can have contact resistance that may cause problems when used in a low voltage situations.
With regard to the G0509, I would also look at the single speed ERL1340 (or RML if looking for a 1440 or 1640) available through Quality Machine Tools and a few other vendors. It is made in Taiwan, very high quality, and get it with a single speed motor that will purr like a kitten with a VFD.
