Abstract
A motor apparatus has a cooling structure capable of effectively cooling the motor by inducing a fluid flow into the motor. In particular, the motor apparatus includes: 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; and a turbine portion coupled to the second part and including disks stacked on one another forming spaces therebetween. 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 an opening hole of each of the disks, and the air is discharged into the spaces formed between the respective disks to cool the motor.
