Patent number: 11606004Abstract: The disclosure relates to a self-cooling motor and a hot-air-circulation device using the same. The self-cooling motor includes a housing, a stator assembly, a rotor assembly and an impeller. The housing includes a sleeve and a bottom plate. The sleeve has a first end and a second end opposite to each other. The bottom plate is disposed adjacent to the first end and forms an inlet facing a radial direction. The rotor assembly coupled to the stator assembly includes a shaft extending outside the housing along an axial direction. The impeller is fixed to the shaft and is adjacent to the second end to form an outlet facing the radial direction. When the shaft drives the impeller to rotate, the airflow enters through the inlet and is discharged from the outlet in the radial direction.Type: GrantFiled: February 1, 2021Date of Patent: March 14, 2023Assignee: DELTA ELECTRONICS, INC.Inventors: Hou-Chu Chen, Yueh Hsiung, Kun-Chou Lee, Chin-Chu Hsu
