Abstract

The invention discloses an externally controlled excitation pole-changing motor. The externally controlled excitation pole-changing motor includes 1 an excitation solenoid, 2 an external circular magnetizer, 3 a stator solenoid, 4 an inner stator magnetizer, and 14 an active magnetic control system lidesheng. The built-in control information of 14 the active magnetic control system lidesheng is output via 9 an active magnetic control system lidesheng control port 1 and input via 7 an input port 1 and output via 13 an active magnetic control system lidesheng control port 2 and input via 10 an input port 2 to supply power to 1 the excitation solenoid, 1 the excitation solenoid is electrified to generate an N / S variable heteropolar magnetic field, the variable heteropolar magnetic field generated by the 1 excitation solenoid and the rotor synchronously cut 3 the stator solenoid, 3 the stator solenoid cut magnetic line generates AC voltage to be output via 15 an output port 1 and 16 an output port 2 to realize complete closing to generate a cutting magnetic field. The aim of speed and driving adjustment is realized by a reverse cutting magnetic field.

Description

technical field [0001] The present invention relates to an externally controlled excitation type pole change technology for multi-field applications such as excitation pole change, and in particular to a device that uses an outer annular magnetizer to control the magnitude of the current in the excitation wire; And other devices that use the drive motor and adjust the speed at any time (referred to as "external control excitation pole-changing 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 provides an externally controlled excitation pole-changing motor technology aiming...
