The paper presents the calculation results of synchronization processes trough AC and DC excitation voltage for a selected model of two-speed synchronous motor with switchable armature and field magnet windings. The synchronous motor type GAe 1716/20t is used for driving the main fans type WPK 5.3 in deep underground mines. The effect of the instant of starting synchronization out of asynchronous operation and greater then nominal value of excitation voltage on the process's effectiveness and the dynamic waveforms was presented. The influence of AC excitation voltage on armature current, field current, field-winding-terminal voltage, electromagnetic torque and rotational speed during synchronization processes has been demonstrated. The calculation results are presented as diagrams over time.

The work presents calculation results of synchronization process of a two-speed, silent-pole, high power synchronous motor. The calculations were based on the examined two-dimensional, field-circuit model for the high power motor, type GAe 1716/20t with switchable configuration connection of armature winding and field magnet. The motor is applied in fan drives in underground mines. The influence of the excitation voltage value greater than nominal and nominal during synchronization process on stator currents, excitation current, electromagnetic torque and rotational speed was examined. The influence of constant excitation voltage value and close-loop excitation current control on synchronization process have been compared. Dynamic diagrams of stator currents, excitation current, excitation voltage, electromagnetic torque and rotational speed during synchronization process as results of computer simulation are presented.
