Working Principle
This product features a structure similar to a typical vertical-wound rotor asynchronous motor. Since it operates in a locked-rotor state, its working principle resembles that of an induction motor and transformer. A turbine transmission mechanism is installed on the voltage regulator to induce angular displacement of the rotor or apply braking to it. When the relative angular position of the rotor changes, for single-phase voltage regulators, this alters the interlinked magnetic flux between the stator and rotor windings, thereby changing the induced electromotive force in the secondary winding. For three-phase voltage regulators, it modifies the phase angle of the induced electromotive force on both the stator and rotor windings. Through a self-coupled circuit connection, this enables smooth, stepless variation of the output voltage.
1.The primary winding of a three-phase voltage regulator can be placed either in the stator or the rotor, depending on the design. The connection between the primary winding and the secondary winding is as shown in Figure 1 (a).
