Abstract
Disclosed herein is a power apparatus including a first motor, a second motor connected with the first motor in parallel, a driver configured to supply driving currents to the first and second motors, a current detector configured to detect the driving current of the first motor and the driving current of the second motor, a speed calculator configured to calculate a rotating speed of the first motor and a rotating speed of the second motor, and a controller configured to control the driver based on the rotating speed of the first motor, wherein the controller controls the driver so that the rotating speed of the first motor and the rotating speed of the second motor are the same as each other, when the rotating speed of the first motor and the rotating speed of the second motor are different from each other.
