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 motor drives the rotor shaft to rotate inside the transformer, but the rotation of the motor has the effect of inertia. When the output voltage of the transformer reaches a preset value, the motor will continue to rotate under the effect of inertia. Rotation causes the output voltage of the transformer to deviate from the preset voltage, which means that the transformation ratio of the adjustable transformer cannot be accurately controlled, which limits the popularization and application of the adjustable transformer in the field of high-voltage technology
