Based on the irreversible demagnetization of the permanent magnet (PM) in vehicle permanent magnet motor (PMM), the demagnetization mechanism of PM is presented and the main factor of vehicle high density PMM demagnetization is analyzed in this paper. The design, analysis and optimization method of anti-demagnetization of PMM at home and abroad are proposed. The advantages and disadvantages of anti-demagnetization analysis method are investigated. At the same time, the solutions and research directions are pointed out, and these works will provide useful information for anti-demagnetization design and contribute to the development of the anti-demagnetization technology for vehicle PMM.
