AI Technical Summary
Poor heat dissipation in the front cover of the existing electric motor leads to increased bearing temperature, affecting the mechanical properties and lubrication performance of the bearing and the stability of the electric motor, which may result in unstable equipment operation and shortened lifespan.
A shroud and a guide plate are installed on the front cover of the motor. The air blown by the cooling fan effectively dissipates heat from the front cover. The airflow is guided by the shroud and the guide plate to the cavity between the front cover and the shroud, forming a negative pressure zone to accelerate airflow and ensure good heat dissipation of the bearing.
It effectively reduces the temperature rise of the bearing, avoids noise and wear problems, and improves the service life and operational stability of the motor.
