  • Motor and rotating shaft cooling device thereof
    Patent number: 11581778
    Abstract: A motor and a rotating shaft cooling device thereof are disclosed. A rotating shaft of the motor is formed with an annular space. A shaft has a front end and a rear end. The shaft is a blind tube formed with a channel communicating with the annular space through a plurality of nozzles. The distance between the nozzles and the rear end is less than one-half of the length of the shaft. A cooling fluid flows through the nozzles to form a jet array to impinge on the inner wall of the rotating shaft to cool the rotating shaft, and flows back in the annular space to enhance the cooling effect, increase the heat exchange area, and improve the cooling effectiveness of the rotating shaft.
