Návrh pohonu výtahu s polovodičovým měničem

Abstract

In this diploma work I solve the suggestion of modernizing the elevator drive by using the frequency converter. I deal here with the possibility of a better exchange process of the original worn-out and technically unsuitable elevators for new ones. In the suggestion I am concerned with two possibilities of the new machines. The first one is substitution by a new short-circuit armature asynchronous motor, and the second one is substitution by a gearless synchronous machine. Calculations of the static and dynamic parameters of both drive types are mentioned here. These parameters are used for a correct suggestion, the motor dimensioning, and the frequency converter. Wiring of the guiding switch-board is modified for operating with a frequency converter. Metering results provided with the help of the suggested types of elevators are enclosed. In conclusion I compared all variants of operating this type of elevators.
