Through the technical scheme provided by the invention, the technical problem that the supporting stability of the structure for supporting the diaphragm belt in the magnetron in the prior art is relatively poor can be solved.

The application provides a magnetron structure. The magnetron structure comprises a main body part having a containing cavity; the main body part has a plurality of vane parts which are arranged at intervals around the containing cavity; a gap between two adjacent vane parts forms a resonant cavity; the resonant cavity is arranged in communication with the containing cavity; a mounting groove and a diaphragm belt, the mounting groove is arranged on the plurality of vane parts and is in communication with the resonant cavity to form an annular groove; the diaphragm belt is arranged in the mounting groove; wherein the mounting groove comprises a shallow groove section and a deep groove section, along the extension direction of the containing cavity, the depth of the deep groove section is greater than the depth of the shallow groove section; the shallow groove section and the deep groove section are at least two, and the shallow groove section and the deep groove section are arranged alternately at intervals. Through the technical scheme provided by the application, the technical problem of poor support stability of the structure for supporting the diaphragm belt in the magnetron in the prior art can be solved.

This utility model relates to the field of power motor technology, specifically a floor scrubber motor, including a fixed base, a fixed connecting ring, a stator assembly, a shaft assembly, a rotor housing, and a rotor assembly. One end of the fixed base has a connecting part that connects to the fixed connecting ring. The stator assembly includes a stator frame and stator windings, with the stator windings mounted on the stator frame. The inner diameter of the stator frame is used to connect the connecting part to the fixed connecting ring. The shaft assembly is mounted on the fixed connecting ring and connected to the rotor housing. The rotor assembly is mounted on the inner wall of the rotor housing and is opposite to the stator assembly. The inner diameter of the stator frame in this utility model securely connects the fixed connecting ring and the connecting part, forming a stable overall structure. During high-speed motor operation, it effectively resists vibration and external impact, reduces relative displacement and loosening between components, and ensures the overall reliability and durability of the motor.

The utility model relates to the technical field of motor stators, in particular to a stator punching sheet which comprises an integrally annular yoke portion, tooth portions evenly distributed along the circumference are arranged in the yoke portion, a tooth groove is formed between every two adjacent tooth portions, one side, close to the yoke portion, of each tooth groove is in an arc shape, the other ends of the tooth portions are all provided with shoe portions, and the shoe portions are arranged on the yoke portion. The shoe part is arc-shaped, the arc length of the shoe part is smaller than that of one side, close to the yoke part, of each tooth groove, and heat dissipation grooves are evenly distributed in the surface, corresponding to the tooth grooves, of the yoke part. The torque output by the motor can be effectively improved, and meanwhile the service life of the motor can be prolonged.

The invention relates to the technical field of motor stator windings, in particular to a semicircular externally-wound alternating current electronic stator winding which comprises a stator core, a plurality of winding grooves are evenly formed in the stator core in the circumferential direction, winding coils are evenly wound on the winding grooves, and the winding coils are wound from inside to outside along the axis of the stator core. The stator core is further connected with a PG plate, the PG plate and the stator core are coaxially arranged, and the diameter of the PG plate is the same as that of the stator core. According to the invention, the anti-interference performance and integrity of the stator winding are improved.
