Jumping switched reluctance motor operating as a hoist

The motor discussed in the paper utilizes the attraction force that an electromagnet exerts on a ferromagnetic yoke. Constituting the motor is a spring placed between the electromagnet and the ferromagnetic yoke, which is located on a guiding track. This arrangement travels in a jumping manner. Presented in the paper is an analysis of the motor´s performance based on the results obtained from a computer simulation of a dynamic model of the motor. Having measured the parameters of the mechanical system and the winding, calculations were performed considering the actual object. The motor´s operation depends on the supply conditions. In this paper, the motor operates as a switched reluctance motor that drives the hoist, i.e. a steady gravity load force and a mass are attached to the yoke. The simulation results show that the motor performs the highest efficiency equal to 23.4%
