摘要：In case of electromechanical equipments driven by alternating current motors, it is possible to reduce the exploitation costs by choosing correctly the driving motor (asynchronous motor or permanent magnet synchronous motor). One of the objectives followed in this paper is the comparative approach from the view point of operation performances and exploitation cost obtained for the two types of motors (asynchronous motor and the permanent magnet one), with the help of some specialized computation soft-wares. The utilization of a permanent magnet synchronous motor, which has an efficiency increased with 11.2% and the power factor better with 10.6%, is a solution for reducing the exploitation cost and for preserving the drive performances.
