The present invention relates to a swing motor control apparatus using a swing brake and a method therefor. More specifically, in a hybrid construction machine wherein a swinging upper part body of the hybrid construction machine is driven by a motor, if it is sensed that an emergency stop switch has been operated or if a temperature of the swing motor is sensed to be higher than a preset critical temperature when the upper part body is in a stationary state, the upper part body can be fixed by applying a swing brake and current of the swing motor can be blocked. As a result, overheating of the swing motor can be prevented using a mechanical brake when the swing motor is overheating.
