Abstract	本发明实施例公开了一种永磁电机。该永磁电机包括：圆环状定子结构和圆环状转子结构；定子铁芯在临近转子结构的环形表面，沿圆周方向设置的多个定子调制齿、电枢齿和电枢槽，按照一定子调制齿、一电枢槽、一电枢齿和另一电枢槽的顺序循环排列，第一定子永磁体与电枢齿一一对应，位于电枢齿临近转子结构的一端，第一定子永磁体沿径向充磁；第二定子永磁体位于对应的电枢槽的槽口，第二定子永磁体沿圆周方向充磁；相邻两个电枢槽对应的第二定子永磁体的充磁方向相反；转子铁芯在临近定子结构的环形表面，沿圆周方向相间设置有多个转子齿和转子槽。本发明实施例的技术方案可直接驱动负载，以摆脱传统传动系统中的中间传动装置。
Other Abstract	The embodiment of the invention discloses a permanent-magnet motor. The permanent-magnet motor comprises an annular stator structure and an annular rotor structure, wherein a stator core is provided with a plurality of stator modulation teeth, armature teeth and armature slots on an annular surface close to the rotor structure along the circumferential direction; the plurality of stator modulationteeth, armature teeth and armature slots are circularly arranged according to the order of one stator modulation tooth, one armature slot, one armature tooth and another armature slot; a first statorpermanent magnet corresponds to each armature tooth and is located at one end, close to the rotor structure, of the corresponding armature tooth; the first stator permanent magnets are magnetized along the radial direction; second stator permanent magnets are located in notches of the corresponding armature slots; the second stator permanent magnets are magnetized along the circumferential direction; and the second stator permanent magnets corresponding to two adjacent armature slots are opposite in magnetization direction; and a rotor core is alternately provided with a plurality of rotor teeth and rotor slots on the annular surface close to the stator structure along the circumferential direction. The permanent-magnet motor disclosed by the embodiment of the invention is capable of directly driving load to get rid of an intermediate transmission device in a traditional transmission system.
