Classification of specifications for electric fan motors

　　The specifications of electric fan motors are generally divided into two types:DC motors and AC motors.Among them,DC motors are divided into brushless motors and brushless motors;AC motors are mainly divided into single-phase motors and three-phase motors.
　　The characteristics of DC motors are low noise,long lifespan,and low power,making them suitable for small electric fans.AC motors,on the other hand,have high power and noise,making them suitable for large electric fans.
