Abstract: Against the backdrop of the large-scale development of offshore wind turbines both domestically and internationally, to reduce operation and maintenance difficulties and enhance the accessibility of maintenance, it is necessary to implement redundant design for medium speed permanent magnet generators. A medium speed permanent magnet generator based on redundant reliability design was introduced, and conducts simulation analysis of its electromagnetic characteristics and cooling performance was conducted. Comparing the design values with the type test values, the results indicate that the generator performs well in electromagnetic and mechanical characteristics, meeting the requirements for redundant operation. The successful development of the prototype provides an important reference for the ongoing development of high-reliability medium speed permanent magnet generators.
