WIPO Patent Application WO/2018/020631

A1

An electric motor (1) has a rotor (2) and a stator (3). The rotor (2) has a rotor core (21) and a plurality of permanent magnets (22) fixed on the outer surface of the rotor core (21). The stator (3) has a stator core (31) having tooth portions (312) and has windings (32) wound around the stator core (31). When the minimum distance from the center of end surfaces (312a) of the tooth portions (312) to the permanent magnets (22) is denoted by t1 and the distance from ends (312c) of the tooth portions (312) to the permanent magnets (22) is denoted by t2, the electric motor (1) satisfies an equation of 1
