发明名称 PERMANENT MAGNET SYNCHRONOUS MACHINE AND COMPRESSOR USING THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a permanent magnet synchronous machine capable of improving torque and efficiency even when utilization of a reluctance torque is difficult.SOLUTION: The permanent magnet synchronous machine, in which a plurality of magnetic poles 30 each having such a shape as to protrude inwards in the radial direction in a rotator 1 and interlinkage flux Ψp(WB) corresponding to an amount for one phase of a stator coil by a permanent magnet 3 forming the magnetic pole 30 and direct-axis and lateral axis inductance Ld(H), Lq(H) when a current effective value Irms (Arms) is passed through a stator coil satisfies the following formula (1), includes slits 7a each being formed from nonmagnetic material at the outer-peripheral portion of a permanent magnet 3 in the radial direction.
