To obtain a permanent magnet motor capable of reducing a decrease in torque due to demagnetization and increasing torque per unit of magnet weight. When the number of poles of permanent magnets is set to P and the number of slots is set to N, the relationship of P:N=2n:12n is established, where n is an integer equal to or more than 2; an air gap length between the inner circumference of a stator core and the outer circumference of the permanent magnet is less than or equal to 1.0 mm; the permanent magnet does not contain a heavy rare earth element and is embedded in a rotor core except for a curve portion of an outer circumference portion; and a circumferential center thickness of the permanent magnet is 2.4 to 4.2 mm.
