The Study of the Synchronous Motor

Abstract

This paper presents the mechanical and electrical characteristics of the synchronous motor. The test setup is presented and used to determine the mechanical and electrical characteristics of the synchronous motor. Modeling the resistive torque allows the loading with different capacities and torsional vibrations. The characteristics of the synchronous motor are presented, as a function of different torques for a constant speed until the fall out of step occurs. The mechanical characteristics, as well as rotational speed and power, as a function of torque, until reaching the loss of synchronism, are plotted. Furthermore, the efficiency of the motor for an operation process that reaches the loss of synchronism is presented.
