【Abstract】 In this paper, the working principle of NdFeB magnetic force lifter is discussed, and then 500kg type of NdFeB magnetic force lifter has been designed and developed, which is of small volume, stable properties, high safe factor, being advantageous over AlNiCo one with safe factor decreasing greatly during working. It will be widely used in machining, mould manufacturing, and metallurgy etc.更多还原
