Abstract
Provided is a rotating electric machine () including a stator () and a rotor (). The rotor () includes a plurality of stages of rotor units (and) stacked in an axial direction. Each of the rotor units (and) includes a pair of permanent magnets () and slits (and) arranged in one or more rows. The slits (and) has an arc-like shape. Both ends of the arc-like shape are located on an outer periphery side of the rotor (). When an angle formed between two straight lines that connect positions of both ends of the arc-like shape and a rotation axis center of the rotor () is defined as an arc angle, at least one of the arc angle of the slit () and the number of rows of the slits is different between at least two rotor units (and).
