Description

Technical Field

[0001] This utility model relates to the field of AC motor technology, specifically to an AC motor with a leakage protection structure. Background Technology

[0002] In modern industrial production and daily life, AC motors, as the core equipment for converting electrical energy into mechanical energy, are widely used in many fields such as power, machinery, and home appliances. With the increasing complexity of motor usage scenarios, such as humid industrial environments and outdoor operations, the safety and reliability of motors face severe challenges. Traditional AC motors have many shortcomings in structural design, making it difficult to meet the current demand for high performance and high safety of motors. On the one hand, the support structure of traditional AC motors is not very stable. During operation, the motor is prone to positional deviation due to factors such as vibration and external impact, which leads to misalignment of the relative positions of the internal stator and rotor, thereby affecting the normal operation of the motor, increasing the probability of failure, and shortening the service life of the motor. On the other hand, the limitation of heat dissipation performance also restricts the working efficiency of the motor. Relying on simple heat dissipation methods alone is not enough to quickly dissipate the large amount of heat generated by the generator. Overheating of the motor will not only reduce performance, but may also cause serious problems such as insulation aging and short circuits. In terms of protection, the casing of traditional motors is not sufficiently protective and cannot effectively resist the intrusion of external objects and moisture, posing a risk of leakage and threatening the personal safety of operators and the stable operation of equipment. At the same time, the internal sealing performance of the motor is poor, and impurities such as dust and moisture can easily enter, affecting the insulation performance of the motor and accelerating the aging and damage of components. In addition, traditional motors are inconvenient to maintain, and the complex disassembly and assembly structure increases the difficulty of inspection and maintenance and the maintenance cost. Moreover, the friction loss of the rotating parts of the motor is large, resulting in low energy utilization and low transmission efficiency.

It is mainly used to support components such as fixing rings. Column No. 1 is firmly connected to the base plate, such as by welding, to ensure that it can withstand the corresponding pressure and vibration when the motor is running, and to provide stable support for the upper structure of the motor. 3. Fixing ring: The fixing ring is a ring structure whose inner diameter is adapted to the size of the relevant components of the motor. It is installed on the top of the No. 1 column. Its main function is to fix and limit certain components of the motor to prevent them from shifting during operation. The fixing ring is tightly connected to the No. 1 column by bolts or welding to ensure the reliability of the fixation. 4. Connecting block: The connecting block is an intermediate structure used to connect different components. Its shape depends on the specific connection requirements and may be square, trapezoidal, etc. The connecting block has multiple connecting holes. Different components of the motor, such as mounting rings and fixing rings, can be connected together by bolts and other connecting parts, so that the components form an organic whole and enhance the stability and integrity of the motor structure. 5. Expansion bolts: Expansion bolts are fastening components used to fix the motor to the mounting base. They consist of bolts, expansion sleeves, etc. During installation, the expansion bolts are driven into the pre-drilled mounting holes, and then the bolts are tightened, causing the expansion sleeves to expand and press tightly against the wall of the mounting hole, thereby achieving a firm connection between the motor and the mounting base and preventing the motor from loosening or shifting during operation. 6. Mounting ring: The mounting ring is a ring-shaped structure that surrounds the motor housing and other components. Its surface is usually machined with threaded holes for connection with other components. The main function of the mounting ring is to facilitate the installation and fixation of the motor to the external structure.

The function of the limiting groove is to limit certain components of the motor, prevent unnecessary movement and shaking during operation, ensure the relative position accuracy between the components of the motor, and improve the running stability and reliability of the motor. 13. Limiting ring: The limiting ring is a ring-shaped limiting structure whose outer diameter matches the inner diameter of the limiting groove. The limiting ring is installed on the corresponding component and works in conjunction with the limiting groove to precisely limit the position of the component. The limiting ring can prevent the component from being displaced in the axial or radial direction, ensuring the stability and accuracy of each component of the motor during operation. 14. Fixing column: The fixing column is a column-shaped structure used to fix important internal components of the motor. It is usually made of high-strength materials. One end of the fixing column is fixed to the motor housing or other supporting components, and the other end is used to install and fix the core components of the motor such as stator and rotor. The fixing column is tightly connected to the core components by bolts and other connecting parts to ensure the stability and reliability of the core components during operation. 15. Movable column: A movable column is a column structure with a certain degree of freedom of movement. One end of it is connected to the base plate of the motor or other components through a movable connection, such as a hinge. The movable column can swing or move within a certain range. Its function is to adapt to some possible deformation or displacement during the operation of the motor, and at the same time, it can also play a certain role in buffering and reducing the impact force on the motor. 16. Buffer pad: Buffer pads are generally made of elastic materials such as rubber and come in various shapes, such as round and square. Buffer pads are installed at the connection between motor components, such as between the column and the base plate, or between the fixing ring and the component. Their function is to absorb the vibration and impact generated during motor operation, reduce wear and noise between components, and improve the operating comfort and stability of the motor.
