Problems solved by technology

[0002] In low-voltage and ultra-low-voltage power transmission and transformation, transformers are irreplaceable devices. Although there are many types of existing transformers, most of them are designed as specific transformer structures. For some special fields, it is often necessary to adjust and transform the transformer , the general transformer cannot be realized conveniently. The motor is used to control the rotation of the rotor shaft to change the relative electrical angle of the stator and the rotor. The stator is the primary winding of the transformer, and the rotor is the secondary winding of the transformer, so as to continuously change the voltage. Output size, realize the ratio adjustment of input and output voltage

[0003] The disadvantage of the prior art structure is that the output voltage of the transformer needs to be changed by changing the rotation angle of the rotor shaft. For a transformer with this structure, the output voltage of the transformer is usually collected by the voltage collector and fed back to the controller. When the collected output voltage reaches the preset voltage, the rotor shaft will continue to rotate due to inertia until it stops rotating. At this point, the output voltage will deviate from the preset value and cause adverse effects on the use of external electrical equipment.
