Abstract: A rotor is formed such that a concave section is formed on the q axis and a gap between the concave section and a tooth of a stator is larger than a gap between an outer circumferential section and the tooth on the d axis. The concave section is formed in a substantially trapezoidal shape and formed such that an opening degree θp2 on an outer circumference side is large with respect to an opening degree θp1 on an inner circumference side. The opening degree θp2 is set within a range of approximately 60 degrees in the electrical angle. A slit is not formed near the d axis on the outer circumference side of the permanent magnet insertion hole and a plurality of slits are formed on left and right both sides a predetermined distance or more apart from the d axis.
