There is no tie to small motors. It just comes with one in the demo kit. Click the link and you'll see another link on that page to show you the product. It is 2 boards, the bottom one has some puny power electronicsa nd a small motor.

Are all BLDC motors 3-phase? I can't seem to find a direct answer to that question.

edit: oh yeah, that DSC has 6 PWM output lines for controlling 3-phase low-and high-side drive. It also has the ability to swap which PWM registers are controlling which PWM outputs, so you can generate a 6-step BLDC drive by simply rotating which output sees which register set, instead of rewriting each register in sequence.
