摘要
Provided is a method for commutating, on the basis of an absolute encoder, a BLDC (Brushless DC) motor having a stator and a rotor. Here, the absolute encoder is constructed to rotate dependently on rotation of the rotor, and the method comprises the steps of: obtaining the output value of the absolute encoder; determining the location of the rotor of the BLDC motor on the basis of the output value of the absolute encoder; and applying a control signal to the BLDC motor on the basis of the determined location of the rotor. Thus, since a Hall sensor is not included, minimization and weight reduction is possible and a thorough control of the rotation in a stationary state and a control in a low speed and low torque is also possible.
