World Electric Vehicle Journal : Comparative Study of Permanent Magnet, Conventional, and Advanced Induction Machines for Traction Applications
This paper investigates and compares the torque-generating capabilities and electromagnetic performance of advanced non-overlapping winding induction machines (AIM), conventional induction machines (CIM), and interior-permanent magnet (IPM) machines for electric vehicle (EV) applications.
Figure 1. Two-dimensional views of the compared machines: (a) IPM (48S/16M/8P). (b) CIM (48S/52R/8P). (c) AIM (24S/26R/8P).
All investigated machines are designed based on the specifications of the Toyota Prius 2010 IPM machine. The steady-state and flux-weakening performance characteristics are calculated by employing the 2D finite element method and MatLab, and the obtained results are quantitatively compared. Furthermore, the torque-generating capabilities of three machines are investigated for different electric loadings, and the machine having the highest torque-generating capability is determined as AIM. Moreover, the major parameters affecting the torque-generating capability, such as magnetic saturation and magnet demagnetization, are examined in depth.
