Abstract: A power system may include a first motor, a second motor connected in parallel to the first motor, a driver configured to supply a driving current to the first motor and the second motor and a controller configured to control the driver based on the driving current and a rotating speed of the first motor, and when the rotating speed of the first motor is different from a rotating speed of the second motor, the controller may control the driver so that the rotating speed of the first motor is equal to the rotating speed of the second motor. The power system may drive two and more motors at the same speed by applying the driving voltage based on the rotating speed and the driving current of one of two or more motors, using a single driving apparatus.
