CALCULATION OF ELECTRICITY CONSUMED PER OPERATING CYCLE BY ELEVATOR GEARLESS ELECTRIC DRIVE ON THE BASIS OF A PERMANENT MAGNET SYNCHRONOUS MOTOR

Abstract

The paper presents a technique and an example of calculating electric energy consumed by an elevator drive on the basis of a synchronous motor with permanent magnets during the basic elevator operating cycle, with the expressions for acceleration and speed under start-up and deceleration conditions according to close to optimal s-tachogram of elevator speed change (sinusoidal law of change in jerk) being used.
