Модернізація системи керування ліфтом багатоповерхового будинку

Abstract

За результатами досліджень з метою покращення ефективності роботи ліфта багатоповерхового будинку було створено систему підпорядкованого регулювання з керуванням по контуру швидкості та струму.

Based on the results of the research, a system of subordinate regulation with speed and current contour control was created in order to improve the efficiency of the elevator of a multi-story building. The power of the drive motor was calculated, an electric machine was selected - an asynchronous motor with a short-circuited rotor. Checks for overheating and overload capacity have been carried out. The technical and economic calculation of the electric drive system was also carried out, based on the results of the calculation, the frequency converter - asynchronous motor system was selected. The mechanical characteristics for the nominal mode of operation are calculated and constructed.
