Segmented rotor type magnetic flux switching motor with hybrid excitation and magnetic adjustment method

Abstract

The invention discloses a segmented rotor type magnetic flux switching motor with hybrid excitation and a magnetic adjustment method. The motor comprises a stator yoke, a permanent magnet, an exciting winding, an armature winding, a segmented rotor and a non-concentrating flux sleeve, wherein the stator yoke is of a 12-tooth structure and formed by arranging excitation teeth and armature teeth in a staggered mode; the permanent magnet is arranged in the excitation teeth, one surface of the permanent magnet is opposite to the rotor, and two sides of the permanent magnet are provided with concentrating flux bridges; the armature winding and the exciting winding are integrated windings and respectively wound on the excitation teeth and the armature teeth; the segmented rotor is arranged in the non-concentrating flux sleeve, thus the whole rotor forms a cylinder structure; the concentrating flux bridges at the two sides of the permanent magnet provide return circuits for electro-exciting magnetic fields generated by the exciting winding, thus permanent magnet magnetic fields are closed after passing through the permanent magnet, the stator yoke, air gaps and the segmented rotor in sequence, and electro-exciting magnetic fields are closed after passing through the stator yoke, the air gaps and the segmented stator; and a current of the exciting winding is adjusted to realize wide-range magnetic adjustment. The motor has the advantages of wider magnetic adjustment range, good fault-tolerant capability and small wind resistance and oil resistance and can be applied to the field of high-speed aviation.

Description

technical field [0001] The invention relates to a segmented rotor type mixed excitation magnetic flux switching motor and a magnetic adjustment method, which are suitable for the field of mixed excitation high-speed aviation. Background technique [0002] In recent years, with the rapid improvement of people's living standards and consumption levels, my country's consumption of natural energy has risen sharply, and various non-renewable energy sources have gradually shown an absolute reduction trend. Energy conservation and emission reduction have become an enduring topic. Therefore, while the application fields of motor drive and speed control systems are continuously expanding, various economic and technical indicators are also undergoing earth-shaking improvements and changes. New types of drive and speed-adjustable motors, which are widely used in social life, production and military fields, have become the focus of current research. [0003] With the continuous improve...
