As a key component in the drive motors of electric vessels, NdFeB permanent magnets are primarily characterized by their high magnetic energy product. To withstand demanding conditions such as high temperatures, applications require the selection of heat-resistant permanent magnet materials and optimized thermal management designs. This product predominantly utilizes block magnets and employs segmented assembly techniques to effectively reduce eddy current losses in the motor, thereby further enhancing motor efficiency to meet the power requirements of vessels of varying sizes.
