PROBLEM TO BE SOLVED: To solve the problem of an embedded magnet type rotor that the degree of freedom in the shape of a permanent magnet is very low when a permanent magnet of different shape is inserted into a magnet embedding part of a rotor core because one and one correspondence exists between the shape at the magnet embedding part and the shape of the permanent magnet of the rotor core, and the amount of a flux being generated from the rotor decreases significantly due to an increase in the magnet embedding part of the rotor core and an air gap of the permanent magnet except an injection molded resin magnet. SOLUTION: When a permanent magnet is inserted into the magnet embedding part of a stator core larger than the shape of the magnet, it is secured to its air gap part through a magnetical conductive resin.
