Abstract

The invention discloses an internal control excitation pole-changing three-phase motor. The internal control excitation pole-changing three-phase motor is composed of an 1 excitation solenoid, an 2 internal I-shaped magnetizer, a 3 stator solenoid, an 4 external stator magnetizer and an 14 active magnetic control system lidesheng. The built-in control information of the 14 active magnetic control system lidesheng is respectively outputted by an 9 active magnetic control system lidesheng control port 1 and outputted by an 7 input port 1 and an 13 active magnetic control system lidesheng control port 2 to supply power to the 1 excitation solenoid through an 10 input port 2. The 1 excitation solenoid is electrified to generate an N/S variable hetero-polarity magnetic field. The variable hetero-polarity magnetic field generated by the 1 excitation solenoid and a rotor synchronously cut the 3 stator solenoid. The magnetic lines of force of the 3 stator solenoid are cut to generate AC voltage passing through an 15 output port 1 and an 16 output port 2. An 17 output port 3, an 18 output port 4, an 19 output port 5 and an 20 output port 6 are completely closed to generate a cutting magnetic field. The objective of speed regulation and driving can be realized by utilizing a reverse cutting magnetic field.
