of machine inductance along the direct (d) and quadrature (q) axes. It behaves like a salient-pole
synchronous motor having direct and quadrature d–q axis machine inductances. e main challenges
of designing an IPM synchronous motor are as follows:
• Create variations of d–q axis inductances without varying air gap.
• Vary and control excitation of permanently excited rotor of IPM rotor.
• Optimum variation PM torque and reluctance torque for specic applications.
• Use of intelligent power converter and inverter modules for IPM drive.
• Reduction of weight, size, and cost of IPM motor.
