To provide a permanent magnet type motor having reduced torque ripple, in which torque ripples for electric angle sixth order and twelfth order are both reduced with a small skew angle. Driving is performed such that phases of currents flowing in two sets of three-phase armature windings 26-1 and 26-2 are different from each other by 20 degrees to 40 degrees in electric angle. A rotor 11 is composed of m stages of rotor component units arranged in the axial direction. The m stages of rotor component units are skewed to have a stage-skew structure such that a skew angle θ (unit: degree) between the adjacent units satisfies 26/m≰θ≰43.2/m (m is an integer equal to or greater than 2) in electric angle.
