Power(BK2008228)”,a permanent magnet synchronous linear motor in the free piston
power generation engine is studied.The structural features in the design of tubular
the development status of the tubular linear motor s仃ucnlre design is analyzed.
Through the introduction of finite element theory applied in the the motor
magnet linear motor in ths paper is a key part ofthe free piston power generation engine. The tubular permanent magnet linear motor owes characteristics of simple structure,
strong output,widely used and SO on.Based on this,the internal principles and basic
stmctllre of the tubular permanent magnet linear motor are introduced and the
introduced,the advantages and disadvantages of various control strategies are compared. Finally,a variety of selection methods about control strategy are introduced,and then
gap harmonic content are analyzed.The choice of tubular linear motor internal
parameters is optimized by Ansofi software.A set of practical motor optimal design
