Quantitative Comparison of Vernier Permanent-Magnet Motors with Interior Permanent-Magnet Motor for Hybrid Electric Vehicles

Study on interior permanent magnet synchronous motors for hybrid electric vehicle traction drive application considering permanent magnet type and temperature

Recently, interior permanent magnet synchronous motors (Interior-PMSMs) have become known as a good candidate for hybrid electric vehicle (HEV) traction drive application due to their unique merits. However, the dynamic and steady-state behaviors of these motors are quite dependent on the permanent magnet (PM) type, configuration, and volume in rotor structures. This paper uses a novel structur...

Calculating the interior permanent-magnet motor

This paper describes the calculation of torqueina brushless permanent-magnet line-start a.c. motor by means of the ~~UX-MMF diagram in combination with the finite-element method. Results are compared with measured ~~UX-MMF diagrams, with shaft torque measurements, and with torque calculated using the classical phasor diagram.

Loss Minimization Control of Interior Permanent Magnet Synchronous Motor for Electric Vehicles

Abstract This paper aims to improve efficiency in interior permanent magnet synchronous motor(IPMSM) drives for electric vehicles. The controllable electrical loss which consists of the copper loss and the iron loss can be minimized by the optimal control of the armature current vector. The control algorithm of current vector minimizing the electrical loss is proposed and the optimal current ve...
