An AC motor is more regularly ment of induction motor driving system used in lift. The fundamental used because of its ruggedness and simplicity. A motor is operation of the induction motor drive hardware and software are introduced, and the different control techniques are described. Next, chosen depending on design intent for the lift. Required several issue related to dimensioning of drive system is considered. power to start the cab in motion is equal to the power to Lastly, this paper discusses practical problems in the realization of the overcome static, or stationary friction, and to accelerate the lift system and represents a response to series of compromises and mass from rest to full speed. Considerations that must be problems incurred during the process of designing, testing and servic- ing. included in the choice of an acceptable motor are good
