The permanent magnetic materials are extensively applied in various electrical machines. Accurate calculation of equivalent field excitation of permanent magnet is very important in electromagnetic field analyzing on designing and researching of PM （permanent magnet） machines. The different kinds of permanent magnet model in analysis and numerical methods of electromagnetic field computation were investigated in this paper. The principles and implementation methods of each method were analyzed and their characteristics were compared. Improving suggestions to the boundary equivalent current method and element equivalent current method were given in this paper.
