Problems solved by technology
Although this structure can improve the requirements of different working conditions, because the two motors do not work at the same time, and the clutch is very large in size and weight in order to meet various working conditions, the power density of the system is very low, and due to the existence of the clutch , which makes the system less efficient, and also produces greater mechanical vibration and noise

The invention relates to a variable structure motor system, comprising a main controller, a variable structure driver and an independent winding motor; the main controller receives control instructions and feedback information of the permanent magnet independent winding motor, and generates power driving and driving topology variable structure instructions , the variable structure driver converts the drive topology structure according to the drive topology variable structure command, and the variable structure driver converts the winding drive mode of the independent winding motor into N star structure or independent H bridge structure. When the independent H bridge structure is adopted , the multiple windings of the motor are connected in series, and the variable structure driver drives the independent winding motor according to the power drive command. The variable structure motor system of the present invention can meet the requirements of different working conditions. Compared with the multi-motor + clutch structure, the weight and volume of the motor drive system can be effectively reduced, the power density can be effectively improved, and the mechanical noise can be eliminated.
Description
technical field [0001] The invention relates to a variable structure motor system, which belongs to the field of motors. Background technique [0002] With the development of high-power-density magnets and power devices, the application of motor systems, especially permanent magnet motor systems, continues to expand, such as the development of all-electric vehicles, all-electric tanks, and all-electric ships. The working conditions of key power mechanisms and propulsion power sources are often complex and often changeable, such as high speed, low speed, light load, overload, normal and fault conditions. [0003] In the prior art, in order to make the motor system meet the requirements of different driving conditions, a structure of two motors + clutches is usually used, such as a high-speed motor + a low-speed motor through a clutch, and the corresponding motors are switched to work according to different working conditions. Although this structure can improve the requireme...
