| Summary: | In the article the technique of the mathematical description and researches of the two- speed asynchronous electric drive for the passenger lift of a traditional design is offered. The mathematical model is presented and its elements are described. The attention is paid to nonlinearities of the two-speed asynchronous electric drive and to detailed analysis of its energetic indices. The results of research of electromechanical transformation in the mechanism of the passenger lift with the two - speed asynchronous motor by a method of mathematical modeling are submitted. At researches are taken into account: variable parameters of an equivalent circuit of the asynchronous motor at work on high and low speeds, variable value of а worm gear reducer efficiency, load of a cabin, direction and real structure of a motion cycle of the lift, which moved under the optimum diagram. The results of modeling are checked up and are confirmed experimentally on the working passenger lift. |
