Description
Technical Field
[0001] The present invention relates to the technical field of hybrid excitation motors, and in particular to a magnetic circuit decoupling hybrid excitation motor with integrated compensation winding. Background Art
[0002] In DC power generation systems, permanent magnet generators (PMGs) offer the advantages of high power density and efficiency. However, permanent magnets are expensive, increasing the cost of the power generation system. Furthermore, since magnetic field regulation in PMGs is difficult, they require a controlled rectifier unit to achieve voltage regulation. This complicates power generation control and reduces system reliability. By incorporating an electric excitation section into a PMG, a hybrid excitation motor can be constructed. Compared to a PMG, a hybrid excitation generator replaces the controlled rectifier unit with an uncontrolled rectifier unit. This allows voltage regulation and motor demagnetization in the event of a motor fault by simply adjusting the DC excitation current. This eliminates the need for rotor position detection, simplifying power generation control and significantly improving system reliability.
[0003] Hybrid excitation generators with magnetic decoupling offer advantages such as high magnetic adjustment efficiency, a wide bidirectional magnetic adjustment range, and minimal risk of permanent magnet demagnetization, while maintaining a simple and reliable hybrid excitation motor structure. These advantages hold great promise for application in DC power generation systems. However, due to differences in the characteristics of the permanent magnet and electrically excited magnetic circuits, the armature reaction of these hybrid excitation generators under load generates reactive power flow in both the permanent magnet and electrically excited motors. This reactive power generation limits the power output capability of these hybrid excitation motors, diminishing their advantages in DC power generation systems.
[0004] Therefore, how to improve the power output capacity of the magnetic circuit decoupling hybrid excitation generator without increasing the complexity of the motor structure and the complexity of the control method has become a research direction. Summary of the Invention
