Thrust force distribution on the surface of stator and rotor poles of switched reluctance motor

An effort is made to establish an effective means of determining the optimum geometrical configuration for such a motor. It is necessary to know the thrust force distribution as a function of the relative displacement between stator and rotor pole faces. The authors discuss the problem of the force distribution for a linear switched-reluctance motor whose structure is very simple. Taking the narrowness of the air gap into account, it is possible to establish a method for measuring the thrust force by introducing the concept of partial magnetic flux
