Description

Technical Field

[0001] The invention belongs to the field of structural design and manufacturing of three-phase asynchronous motors, and in particular relates to a butt-jointed three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a commonly used motor. The speed of its rotor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion. The existing three-phase asynchronous motors often have a high speed and high internal heat when running. For this reason, it is generally necessary to design an intake blade at the rear end of the drive shaft to inhale airflow and dissipate heat through air intake. For this reason, it is generally necessary to install a filter plate on the outside of the rear end of the casing to filter the inhaled airflow through the filter plate to prevent internal pollution of the casing. However, after a period of operation, the filter plate will be blocked. For this reason, the filter plate needs to be replaced regularly, which is a cumbersome operation. At the same time, the motor often cannot be replaced during operation, which is inflexible. For this reason, the structure needs to be redesigned to improve the flexibility of use and avoid the cumbersomeness of replacing the filter plate. Summary of the invention
