Abstract

The invention creatively discloses a laterally controlled excited pole-changing motor. The laterally controlled excited pole-changing motor comprises an excitation solenoid (1), a lateral H-shaped magnetizer (2), a stator solenoid (3), a lateral stator magnetizer (4), an active magnetic control system lidesheng (14) and the like, wherein built-in control information of the active magnetic control system lidesheng (14) is output via an active magnetic control system lidesheng control port 1 (9) and via an active magnetic control system lidesheng control port 2 (13) respectively and power supply of the excitation solenoid (1) is realized through an input port 1 (7) and an input port 2 (10) respectively; the excitation solenoid (1) is electrified to generate a polarized magnetic field with a variable N / S; the variable polarized magnetic field generated by the excitation solenoid (1) and a rotor synchronously cut the stator solenoid (3); and the stator solenoid (3) subjected to cutting of magnetic lines of force generates alternating current voltage and outputs a cutting magnetic field which is generated by completed closure through an output port 1 (15) and an output port 2 (16) respectively. The targets of speed adjustment and driving are achieved by a reverse cutting magnetic field.

Description

technical field [0001] The present invention relates to a side control excitation type pole changing technology for multi-field applications such as excitation pole changing, especially to a device that uses a side I-shaped magnetic conductor to control the magnitude of the current in the excitation wire; electric vehicles, motors, flying objects, Locomotives and other devices that use drive motors and adjust the speed at any time (referred to as "side-controlled excitation 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 control type excitat...
