Routers are generally single phase motors with brushes, not really suited to long switch-on periods. VFD means Variable Frequency Drive and it has 3 phase output at a changeable frequency so you can control the speed and direction of the Spindle, which is a 3 phase motor, usually brushless, so more suitable for continuous use.

Cheers,

Thanks for the explanation. Makes sense now. I'll definitely look into this for the bigger machine.
