Motor apparatus having cooling structure

A motor apparatus having a cooling structure for an air mobility, the motor apparatus comprising:

• a first part having a first flow path and a motor installed thereon;
• a second part having a second flow path, and configured to be rotatably mounted on the first part and connected to the motor to be rotated when the motor is operated, the second part further configured to be coupled to a shaft to rotate a propeller;
• and
• a turbine portion coupled to an inside of the second part and configured to be rotated together with the second part,
• wherein:
• the turbine portion includes a plurality of disks each having an opening hole and disks of the plurality of disks are stacked on each other in a vertical direction of the motor apparatus and form a space between the respective disks,
• the opening holes and the spaces are in communication with each other,
• when the turbine portion is rotated together with the second part, air is drawn through the first flow path or the second flow path and introduced into the opening hole of each of the disks, and
• the air introduced into the opening holes is then discharged into the space formed between the respective disks to cool the motor.
