A hybrid induction motor is provided to simplify a constitution and lower a manufacturing cost by removing a shading coil, a subsidiary coil or a condenser. A hybrid induction motor includes a permanent magnet frame(132), a rotation shaft, a counter-rotation prevention apparatus, a protrusion unit(174), and a stopper(170). The permanent magnet frame(132) supports a permanent magnet rotatably. The rotation shaft rotates to be integrated with a rotor of the permanent magnet. The counter-rotation prevention apparatus is installed on an upper plane of the permanent magnet frame(132), and prevents a counter-rotation of the rotation shaft. A first protrusion is installed on an upper plane of the permanent magnet frame(132) so that the counter-rotation prevention apparatus is rotated with the permanent magnet frame(132) along the counter-rotation of the rotation shaft. A second protrusion(173) is installed to rotate with the permanent magnet frame(132) along the rotation direction of the rotation shaft. The stopper(170) stops the rotation of the rotation shaft when the rotation shaft is counter-rotated.
