Description

Technical Field

[0001] The utility model relates to the technical field of stator structures in motors, in particular to a high-efficiency motor and a stator structure thereof. Background Art

[0002] As core devices for converting electrical energy into mechanical energy, electric motors are widely and indispensable in various fields, including modern industry, transportation, agriculture, and homes. In industry, electric motors drive a variety of production machinery, such as machine tools, fans, pumps, and compressors, serving as the driving force behind industrial production. In transportation, the development of electric vehicles relies heavily on high-performance electric motors. In homes, appliances ranging from refrigerators and washing machines to air conditioners also rely on electric motors. With the increasing number of electric motors in use and their diverse applications, motor maintenance and repair have become crucial. Throughout their lifecycle, electric motors can experience various faults, such as stator winding short circuits, insulation damage, and bearing wear. Diagnosing and repairing these faults often requires access to the motor's internal structure, with the inspection or replacement of stator teeth being a common problem. Traditional stator tooth installation often utilizes numerous bolted connections, welds, or complex nested structures. These traditional connection methods can be quite complex when disassembling stator teeth for repair or replacement. Bolts may be difficult to remove due to rust, thread damage, etc., and welded structures require special cutting equipment to separate. These operations can easily damage other parts of the stator, increasing maintenance costs and time. Therefore, we propose a high-efficiency motor and its stator structure to solve this problem. Utility Model Content

[0003] The purpose of the present utility model is to provide a high-efficiency motor and a stator structure thereof to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The cam is fixedly mounted on the support frame of the motor, and the cam is fixedly mounted on the support frame of the motor to the support member.

[0006] Preferably, the two groups of shells are respectively slidably installed inside the corresponding placement grooves, and a spring 1 is provided inside the two groups of shells. The two ends of the spring 1 are respectively fixedly connected to the corresponding slide plate and the inner wall of one side of the shell.

[0007] Preferably, the two groups of pressure plates are respectively slidably installed inside the corresponding slide grooves, and two groups of springs 2 are provided inside the two groups of slide grooves. The two ends of the two groups of springs 2 located on the same side are respectively fixedly connected to the corresponding pressure plates and one side inner wall of the slide groove.

[0008] Preferably, two groups of limiting grooves are provided on the outer sides of the multiple groups of stator teeth, and limiting bars are provided inside the two groups of half cores, and the two groups of limiting bars are movably engaged in the inside of the corresponding limiting grooves.

[0009] Preferably, connecting rods are fixedly installed on the tops of the two groups of slides, and pull plates are fixedly installed on the tops of the two groups of connecting rods. The two groups of connecting rods slide through the interiors of the corresponding shells respectively, and limiting rods are slidably installed inside the two groups of pressure plates. The two groups of limiting rods are fixedly connected to the inner walls on both sides of the corresponding slide grooves respectively.

[0010] Preferably, multiple groups of stoppers are fixedly mounted on both sides of the two groups of half cores, and the multiple groups of stoppers located on the same side are movably abutted against both sides of the multiple groups of half cores respectively.

[0011] The present invention provides a high-efficiency motor and its stator structure, which are provided with a half core, a mounting block 1, a mounting block 2, a placement groove, a slide groove and a mounting assembly. The limit bars arranged inside the two sets of half cores are movably connected to the inside of the limit grooves provided on the outer side of the stator teeth. First, the two sets of pull plates are pulled horizontally left and right, so that the pull plates drive the connecting rod and the slide plate to move, so that the slide plate drives the plug block to disengage from the inside of the mounting block 2 while squeezing the spring 1. Then, the two sets of pull plates are pressed, so that the housing drives the two sets of fixing rods to move. Under the restoring action of the spring 1 and the spring 2, the pressure plate drives the plug bar to return to the inside of the plug plate, so that the slide plate drives the plug block to be re-inserted into the inside of the mounting block 2. This structure is simple and easy to operate, and is convenient for installation, double fixing and removal of the two sets of half cores outside multiple sets of stator teeth, effectively reducing the time required for installation and removal. The double fixing can effectively prevent the half cores from being displaced or loosened due to factors such as vibration and electromagnetic force generated by the operation of the motor, and is convenient for maintenance and replacement of the half cores and internal parts.

[0012] In the present invention, a high-efficiency motor and a stator structure thereof are provided with limit slots, limit bars and blocks. By movably clamping the limit bars provided inside the two groups of half cores into the limit slots provided on the outside of the stator teeth, multiple groups of blocks are used to facilitate effective positioning of multiple groups of stator teeth, thereby providing a precise positioning reference for the installation of the half cores on the stator teeth, ensuring that the relative position between the half cores and the stator teeth is accurate, and avoiding the position offset of the half cores due to manual assembly errors.

[0021] In this embodiment, two groups of limiting grooves 9 are provided on the outer sides of the multiple groups of stator teeth 5, and limiting strips 3 are provided inside the two groups of half cores 1. The two groups of limiting strips 3 are movably engaged with the corresponding limiting grooves 9, which provides a precise positioning reference for the installation of the two groups of half cores 1.
