Abstract: Cerium magnets for wind power were developed through the dual main phase technology of cerium magnets and grain boundary control technology. Simulation and analysis were conducted using a direct drive 1. 5 MW permanent magnet wind turbine as an engineering case, especially the adaptive design of magnetic steel thickness. In the type test of the prototype, the consistency between the design values and the measured values, as well as the compliance of various performance indicators, were compared to verify the feasibility of the application of cerium magnets in wind power and the feasibility of the overall design scheme of the generator, which could meet the engineering requirements of the unit. The development of a 1. 5 MW cerium magnet prototype had laid a good foundation for the subsequent development and application of higher performance cerium magnets in wind power, and provided important reference basis.
