ABSTRACT:
A power control apparatus for a motor is disclosed. The power control apparatus includes: a moisture sensor for detecting moisture soaking into a housing including the motor; and a switching unit which is switched by an output signal of the moisture sensor, and switches on or off an AC power-supply signal applied to a driver circuit for providing the motor with a drive power-supply signal. Therefore, if moisture soaks into the suction apparatus including the motor, the AC power-supply signal applied to the driver circuit is blocked due to the moisture, such that a user can be protected from electric shock.
