Abstract
A rotor mechanism includes a plurality of rotor bars and a rotor core. The rotor bars are disposed along the edge of the rotor core. The rotor core has a plurality of magnetic flux-barrier units and at least one flux channel. Each magnetic flux-barrier unit extends from one of the rotor bars to another rotor bar. The flux channel passes through the flux-barrier units and surrounds an axis of the rotor core, wherein each magnetic flux-barrier unit is a magnetic flux barrier, and the area between the adjacent magnetic flux-barrier units and the flux channel are pathways for magnetic flux.
