Description

technical field [0001] The present invention relates to a double-side control permanent magnet pole changing technology for multi-field applications such as excitation pole change, and in particular to a device that uses double-sided I-shaped magnetizers to control the magnitude of the current in the excitation wire; electric vehicles, motors, Flying objects, locomotives, etc. use drive motors and devices that adjust speed at any time (referred to as "double-side controlled permanent magnet pole-changing motors"). 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 provides a side-con...
