Abstract

The invention discloses an external control permanent magnetism pole-changing motor. The external control permanent magnetism pole-changing motor comprises 1. excitation coils, 2. an annular magnetizer, 3. a stator coil, 4. an N external permanent magnet 1, 15. an S external permanent magnet 2 and 14. an active magnetic control system lidesheng. The internal control information in 14. the active magnetic control system lidesheng is respectively output through 9. a control port 1 for the active magnetic control system lidesheng, and is output through 7. an input port 1 and 13. a control port 2 for the active magnetic control system lidesheng, and supplies power for 1. the excitation coils through 10. an input port 2; as the 1. excitation coils obtain power, an N / S changeable heteropolarity magnetic field is generated; a 3. stator coil is cut by the changeable heteropolarity magnetic field generated from the 1. excitation coils and the permanent magnets; and cutting and driving of magnetic field is generated as the stator coil is influenced by cutting of magnetic line by the permanent magnets so that speed adjusting and driving can be realized by means of reverse cutting and driving of magnetic field.

Description

technical field [0001] The present invention relates to an externally controlled permanent-magnet pole-changing technology for multi-field applications such as excitation pole-changing, and in particular to a device that uses an outer annular magnetizer 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 "external control 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 an extern...
