Abstract

The invention discloses an internal control permanent magnet pole-changing motor. The internal control permanent magnet pole-changing motor is composed of an 1 excitation solenoid, an 2 internal I-shaped magnetizer, a 3 stator solenoid, an 4 N external permanent magnet 1, an 15 S external permanent magnet 2 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 the permanent magnets synchronously cut the 3 stator solenoid. The magnetic lines of force of the 3 stator solenoid are cut by the permanent magnets to generate a cutting driving magnetic field. The objective of speed regulation and driving can be realized by utilizing a reverse cutting driving magnetic field.
