AI Technical Summary
The existing permanent magnet synchronous motors rely mainly on axial ventilation holes on the stator for air cooling, which cannot effectively remove the heat inside the motor, affecting the motor's performance and lifespan.
The air intake component actively blows air into the inside of the housing, and air cooling is achieved through the gap between the stator and the rotor. The airflow exchanges heat through the air duct between the stator and the rotor, and finally the hot air is discharged from the heat dissipation port, increasing the air flow speed and contact area.
It improves the heat dissipation of the motor, effectively removing heat generated during long-term operation, thus improving the motor's performance and lifespan.
