Modeling the mechanical and electrical characteristics of the synchronous motor

Abstract

This paper presents the mechanical and electrical characteristics of the synchronous motor for variations of the required moment. It is presented the test configuration used to determine the mechanical and electrical characteristics of the synchronous motor. Engine torque modelling allows the shaft to be loaded with various resistive moments generated by an electromechanical brake. The presented characteristics highlight the mechanical characteristic of the synchronous motor, which does not depend on the resistant mechanical torque of the working machine during the technological process. There are presented the mechanical characteristics of the rotation speed depending on the variation of the resistant moment until the synchronism exit of the synchronous motor. The determination of these characteristics is dependent on the variation of the excitation current of the synchronous motor.
