Abstract
An electric motor rotor mechanism includes a plurality of rotor bars and a rotor core. The rotor bars are disposed on the rotor core. The rotor core has a plurality of lines of barriers and a plurality of flux barrier holes. Each of the lines of barriers extends from one of the rotor bars to another one of the rotor bars. The flux barrier holes are arranged along the lines of barriers. Each of the flux barrier holes is a magnetic flux barrier. An area between each adjacent flux barrier hole is a magnetic flux path.
