摘 要：正Single-phase permanent magnet（PM） linear oscillating actuators having alternative topologies are designed and analyzed by finite element analysis,with particular reference to a novel tubular E-core interior permanent magnet（IPM） oscillating *** electromagnetic performance is compared and relative merits are *** shows that the E-core actuators exhibit much less end flux leakage than the C-core actuators,and that the E-core IPM actuator is capable of producing equivalent peak force as the E-core Halbach surface PM actuator with nearly half the PM material used,while the mover structure is much simpler and easier to ***,the design parameters of the IPM actuator,*** magnet pole ratio and the split ratio,are optimized.
