Design of V-Type Consequent-Pole IPM Machine for PM Cost Reduction With Analytical Method

This study proposes an analytical method (AM) for V-type consequent-pole permanent magnet (V-CPM) machines to quickly determine the suitable (PM) volume while reducing PM compared that of interior (V-IPM) machine. Special air-gap magnetic flux density modeling is adopted in AM, which consists 4 asymmetric regions under one and iron pole V-CPM. specific utilized V-CPM topology, has a different saturation trend from conventional surface-mounted CPM (S-CPM). Hence, additional consideration rotor by novel been done previous works. To achieve average torque similar V-IPM machine, machine designed proposed AM have same fundamental harmonic value density. Furthermore, two conditions are considered design prevent unnecessary minimize ripple. All performance metrics with those other demonstrate its superiority.
