Description

technical field [0001] The present invention relates to a double-side controlled excitation type pole-changing technology for multi-field applications such as excitation pole change, in particular to a device that uses a double-sided I-shaped magnetizer to control the magnitude of the current in the excitation wire; Objects, locomotives and other devices that use the drive motor and adjust the speed at any time (referred to as "double-side control excitation pole-changing three-phase motor"). Background technique [0002] At present, the motors directly control the current or voltage and frequency of the main line package on-line. The frequency converter is mainly composed of electronic components. Damage; the frequency converter is an online frequency conversion mode, and the product cost is high; the price of the frequency converter and the motor of this power is similar and high. Contents of the invention [0003] The invention aims at providing a double-side control e...
