摘要: An interior permanent magnet machine is described. The includes a rotor rotatable about central axis. plurality of openings and magnets disposed therein. are separated by webs configured to facilitate reducing leakage flux through the webs. also stator coaxially with from circumferential air gap. teeth that define slots therebetween. include tooth tip cogging torque ripple.
