The reasonable design of the centrifugal fan is very important to the performance of the motor. Although the structure principle of the centrifugal fan on the motor is very similar to that of the impeller of the Centrifugal Fan, most of the designers of the motor are not familiar with the design theory of the impeller of the fan because of the limitation of the specialty, therefore, the centrifugal fan on the motor is still the motor technology needs to be studied. Therefore, the application of Fan impeller design theory to motor design is significant to improve the motor design.
