Abstract：

The linear motor direct drive can improve the velocity, efficient and precision of mechanical press by eliminating any middle transmissions. However, traditional linear motor drive press exists restrictive relation between tonnage, cost and reliability. Therefore, based on summarizing the development status of linear motor drive forging apparatuses, structure schemes of novel linear motor direct drive high speed press were researched. Considering the work characteristics and manufacturing cost of mechanical press, three topologies of flux switch linear motor were designed, in which the secondary mover only consisted of salient pole core. In order to balance the motor normal force, punch structures driven by double flatplates, four side and six side tubular flux switch linear motors were proposed respectively. Thus, the stamping force of mechanical press was enhanced by combining pneumaticelectric with hybrid excitation.
