Magnetic materials in electrical engineering are widely used in electrical equipment such as motors and transformers. Accurate simulation of hysteresis characteristics is very important for the design and application of magnetic materials. The research of hysteresis phenomenon in the field of magnetism has a history of nearly one hundred years. Scholars all over the world have established various mathematical models of hysteresis and developed many improved ones. Starting from the origin of hysteresis model, this paper introduces the development status of typical scalar hysteresis model, vector hysteresis model and hybrid vector hysteresis model, and analyzes the existing problems and future development trend of various hysteresis models. The improved hysteresis model can more accurately simulate the hysteresis characteristics of magnetic materials and provide strong support for practical engineering applications.
