Comprehensive Research on a Modular-Stator Linear Switched Reluctance Motor with a Toroidally Wound Mover for Elevator Applications

This paper presents a novel modular-stator linear switched reluctance motor (MSLSRM) for elevator applications. The topology and its operating principle is illustrated and the magnetic equivalent circuit is derived for the aligned position. To attain the electromagnetic features of the motor, two dimensional and three dimensional finite element methods are employed. The static inductance and force profiles are obtained and the flux density distributions are given. Also, the dynamic operation of the introduced motor is performed. To demonstrate the positive sides of the suggested motor, a fair comparative study is done. To this end, two linear motors are considered and the static performance and dynamic waveforms of the three motors are compared. It is illustrated that the new motor has higher mean force and lower force ripple in comparison with the considered SRMs.
