Description

Technical Field

[0001] The utility model relates to the technical field of motor iron core processing devices, in particular to a three-phase asynchronous motor iron core processing device. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor. It is a type of motor that is powered by simultaneously connecting to a 380V three-phase alternating current (with a phase difference of 120 degrees). Because the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor.

[0003] The rotor speed of the three-phase asynchronous motor is lower than 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.

[0004] The iron core is the core component of the three-phase asynchronous motor, which is used to increase the magnetic flux of the inductor coil to achieve the maximum conversion of electromagnetic power. The iron core of the existing three-phase asynchronous motor is generally composed of multiple stacked silicon steel sheets. Burrs are easily generated on the edges of the silicon steel sheets during the stamping process. These burrs are easy to affect the overall quality of the iron core during the stacking process of the silicon steel sheets. In addition, the commonly used iron core deburring device has less polishing surface and needs to process both sides of the iron core separately, resulting in low processing efficiency.

[0005] Therefore, there is an urgent need for a three-phase asynchronous motor core processing device that can improve deburring efficiency. Summary of the invention
