Description
技术领域 technical field
本发明属于电机制造技术领域，涉及一种磁链并联双转子复合电机。 The invention belongs to the technical field of motor manufacturing, and relates to a flux-chain parallel double-rotor composite motor.
背景技术 Background technique
传统定子永磁型磁通切换电机具有转矩密度和功率密度高的特点，定子与转子均为凸极结构，永磁体与电枢绕组均位于定子侧，转子侧既无电枢绕组也无永磁体，结构简单，机械强度高，适合高速运行，且能够运行于较恶劣的环境条件下。但是，传统定子永磁型磁通切换电机仅采用单转子结构，即仅具有外转子或内转子，工作模式单一。 The traditional stator permanent magnet flux switching motor has the characteristics of high torque density and power density. The stator and rotor are salient pole structures. The permanent magnets and armature windings are located on the stator side. The magnet has simple structure, high mechanical strength, is suitable for high-speed operation, and can operate under relatively harsh environmental conditions. However, the traditional stator permanent magnet flux switching motor only adopts a single rotor structure, that is, only has an outer rotor or an inner rotor, and has a single working mode.
文件ZL201210274466.1提出一种复合式磁通切换电机结构，采用双转子电机结构，内外两个电机彼此独立，分别驱动内外两个转子运行。该电机具有多种工作模式，能有效提高系统运行的灵活性，满足现代电动汽车驱动系统与工业驱动系统中对电机运行灵活性高，可靠性高的要求。但是，复合电机结构由于两个电机定子轭部采用隔磁环隔离，且为了防止内外电机磁场耦合，必然要求定子轭部厚度较大，从而增加了电机体积。 Document ZL201210274466.1 proposes a compound flux switching motor structure, which adopts a dual-rotor motor structure. The inner and outer motors are independent of each other, and drive the inner and outer rotors to run respectively. The motor has a variety of working modes, which can effectively improve the flexibility of the system operation and meet the requirements of high flexibility and reliability of the motor in the drive system of modern electric vehicles and industrial drive systems. However, in the compound motor structure, since the stator yokes of the two motors are separated by a magnetic isolation ring, and in order to prevent the magnetic field coupling of the inner and outer motors, the thickness of the stator yoke must be relatively large, thereby increasing the volume of the motor.
因此，本发明提出一种磁链并联双转子复合电机，通过内外电机磁路并联，构成两条相互独立的功率路径，在实现电机多工作模式的前提下，有效减小了电机轭部厚度，能满足电动汽车及工业驱动系统对电机体积小、结构紧凑、功率密度高的要求。 Therefore, the present invention proposes a flux-linkage parallel dual-rotor composite motor, which forms two mutually independent power paths through the parallel connection of the inner and outer motor magnetic circuits, and effectively reduces the thickness of the yoke of the motor on the premise of realizing the multi-working mode of the motor. It can meet the requirements of electric vehicles and industrial drive systems for motors with small size, compact structure and high power density.
