This is from what they have in there description!!!
There is a connection to the spindle for power. Three of the four connections are used which connect to the internal coils that make the spindle spin. The fourth connection is not connected (NC).
This would be a Electrical code violation, and dangerous for the user, the 4th connection is Ground / Earth connection and is required
There price is also to high for this spindle combo
