Abstract
The paper presents the mechanical and electrical characteristics of the synchronous motor for imposed moment variations at the shaft. The test setup is presented, used to determine the electrical and mechanical characteristics of the synchronous motor. Modelling the resistive torque allows the loading with different torsion vibrations. It is presented the used experimental workbench in order to determine the mechanical and electrical characteristics of synchronous motors in such conditions. The engine torque model allows the shaft to be loaded with variable resistive torque values generated by an electromechanical brake. The characteristics presented show the mechanical characteristic of the synchronous motor. Mechanical rotation speed characteristics are presented based on the variation of the resistive torque for 40 seconds, taking note of the value of the resistance when the motor exits synchronism. The determination of these characteristics are made based on the variation of the excitation current applied to the rotor winding of the synchronous motor.
