Claim 7:
8. The rotor of claim 7, wherein
the first flux barriers each comprise a magnet loading region where the first permanent magnet is disposed, an inner-side cavity extending from the magnet loading region towards the d-axis, and an outer-side cavity extending from the magnet loading region towards the outer circumference of the rotor core,
the second flux barriers each comprise a magnet loading region where the second permanent magnet is disposed, an inner-side cavity extending from the magnet loading region towards the d-axis, and an outer-side cavity extending from the magnet loading region towards the outer circumference of the rotor core, and
the rotor core comprises a first bridge portion formed between the inner-side cavity of the first flux barrier and the d-axis, first outer circumferential bridge portion formed between the outer-side cavity of the first flux barrier and the outer circumference of the rotor core, a second bridge portion formed between the inner-side cavity of the second flux barrier and the d-axis, and a second outer circumferential bridge portion formed between the outer-side cavity of the second flux barrier and the outer circumference of the rotor core.
