MOTOR DEVICE UTILIZING MAGNETIC FORCE TO DRIVE A ROTOR

摘要

A motor device utilizing magnetic force to drive a rotor. The motor device includes a main body, a rotor and a controlling unit. The main body has two openings and an internal chamber. The rotor is magnetic and swingably dispos ed in the chamber between the two openings. The controlling unit is disposed on outer side of the main body to apply a magnetic force to the rotor for driving the rotor to at least rotate. The rotor is a column body with a certain length. The rotor ha s a profile corresponding to a configuration of a peripheral wall of the chamber. The outer face of the rotor is formed with at least one spiral groove to define at least on e spiral stripe. The rotor is magnetically driven to drive a fluid to flow from one opening to the other opening.
