Abstract

This paper presents a multi permanent magnet layers for ∇ -V-U shape rotor designs of interior permanent magnet synchronous motor and permanent magnet assisted synchronous reluctance
motor to maximize the torque and power for wide range capability for electric vehicle applications. Six models of the ∇ -V-U layer shapes of the interior permanent magnet synchronous motor and permanent magnet assisted synchronous reluctance motor are evaluated in the constant torque for wide range speed by analytical torque-current-speed methods. The average, ripple and cogging torque, and the output power are proposed with different rotor magnet designs via an analytical torque model. The rotor topologies are then checked by the analytical method and finite element method for their constant power for wide range performances. It is shown that the ∇ 2U rotor structure with double U layer -permanent magnet assistance has the higher average torque and efficiency for wide range speed up to 20000 rpm.
