The Woodpecker is the entry level model and incorporates motor, bearing and armboard in a solid and fairly substantial slab of plinth, with aluminium facing top and bottom. The motor is a three-phase DC design that acts like a phase locked-loop (PLL) and has all its supply electronics internally which keeps things tidy from a manufacturing perspective. Placing the power inlet underneath the plinth keeps things aesthetically tidy, too, while power is derived from a wall-wart supply that has a power indicator.
*Good conditions. No box.
