The invention relates to a motor and an applied dryer thereof, the motor and the applied dryer thereof comprises a stator intertwined by a main coil and an auxiliary coil, a rotor located at the inner diameter of the stator, a spindle combined with the rotor, two end caps located at two ends and fixedly connected with the stator, and a centrifugal switch. The two ends of the spindle are supported on the end caps through a bearing, the centrifugal switch comprises a centrifugal mechanism and a centrifugal switch implementing mechanism, wherein, the centrifugal mechanism is arranged on the spindle, the centrifugal switch implementing mechanism is arranged on the end caps, a slide block of the centrifugal mechanism can realize the power on and off of the auxiliary coil at circuits by swing arm action of the centrifugal switch mechanism, thereby effectively improving all kinds of operating performance of the motor.
