Abstract

PURPOSE:To form a rotor for an AC electric machine having high operating efficiency by associating a squirrel cage rotor and a permanent magnet rotor with a single rotor, thereby producing it in small size inexpensively. CONSTITUTION:A permanent magnet 3 having a plurality of grooves 3a axially formed on the outer peripheral surface of approximately cylindrical permanent magnet is inserted into a cylindrical yoke 2 having a rotating shaft 1, and is secured to the yoke 2. A metallic conductor 4 made of aluminum or the like is provided in the grooves 3a of the magnet 3, is shortcircuited with a shortcircuiting ring 5 to form a squirrel cage rotor. The ring 5 is formed in a ring shape, is insulated from the yoke 2, and is provided above or below the permanent magnet 3. Since the squirrel cage rotor and the permanent magnet can be associated with the single rotor in this manner, the shape of the AC electric machine is not increased in size, and the operation efficiency can be improved.
