  • Permanent magnet system and method of forming thereof
    Patent number: 11448715
    Abstract: There is provided a method of forming a permanent magnet system, the method including: determining one or more types of geometrical parameters for forming an array of magnet ring pairs including a first subarray of first magnet rings and a second subarray of second magnet rings spaced apart from the first subarray of the first magnet rings along a longitudinal axis; and forming the array of magnet ring pairs based on the determined one or more types of geometrical parameters, whereby the above-mentioned determining one or more types of geometrical parameters for forming the array of magnet ring pairs is based on a genetic algorithm. There is also provided a corresponding permanent magnet system, such as formed by the method.
