Concept of the high reliability motor drive system for lift

A concept of the high reliability motor drive system for lift is described in this paper. Proposed solutions are derived from the practical realization of the lift system and represent a response to series of compromises and problems incurred during the process of designing, testing and servicing. The main purpose of this paper is to address different algorithms and implementation of the high reliability motor drive system for lift. We propose a solution at the block level.
