#$%^&*AU2015408849B220171207.pdf#####Abstract Disclosed is a rotor position estimation method for electromechanical energy conversion bilateral switched reluctance linear motor, applicable to rotor position estimation for bilateral switched reluctance linear motors that have any number of phases. 5 The stator windings of each phase of the bilateral switched reluctance linear motor are composed of four concentration coils, wherein, two concentration coils are arranged on the stator at each side, the two concentration coils on the stator at one side are connected in series to form a stator winding u, the two concentration coils on the stator at the other side are connected in series to form a stator winding d; the inductance values of the stator 10 winding u and the stator winding d are detected online, an overlap distance value d between the stator pole and the rotor pole of the bilateral switched reluctance linear motor is obtained through calculation, and thereby the rotor position is obtained. The accuracy of the rotor position is insusceptible to the influence of the rotor eccentricity. The method disclosed in the present invention sets a basis for sensorless controlling a bilateral switched 15 reluctance linear motor, and has wide application prospects. 8856974_1 (GHMatters) P105254.AU
