Unitized Double Sided Linear Switched Reluctance Motor with Auxiliary Winding for Rope Less Elevators

This paper analyze the Double Sided Linear Switched Reluctance Motor (DSLS-RM) with auxiliary winding for rope less elevators. Linear switched reluctance motor are two types based on the structure, single sided and double sided linear switched reluctance motor. Power electronic devices achieve the modulation of the speed and force developed in the linear motors. Instead, an auxiliary winding can used and modulation of force and speed can be achieved in the double sided linear switched reluctance motor. By using an auxiliary winding in double sided linear switched reluctance motor the flux weakening and strengthening will occurs in the stator, due to which the modulation of force and speed is possible without any power electronic devices. Due to addition of auxiliary winding in the stator the four modes of operation is possible by changing the direction of excitation of the windings. The modulation of force and speed for the DSLS-RM is analyzed using FEA analysis tool (ANSYS Maxwell). The experimental model of the double sided linear switched reluctance motor has been set up, analyzed and compared with simulation results.
