PURPOSE: A motor system is provided to achieve improved accuracy and reliability of control of centrifugal switch, while reducing noises of the motor. CONSTITUTION: A motor system comprises a motor(200) for sensing the speed of the rotor and generating and outputting the pulse signal having the frequency determined by the sensed speed of the rotor; a centrifugal switch(300) which turns on/off by the speed of the rotor; and a switch control unit(100) for converting the frequency of the pulse signal output from the motor into a voltage value and controlling the centrifugal switch to be turned on if the voltage value is higher than the threshold voltage.
