The present invention relates to a motor device capable of reducing a load for stage settings, which is intended to extend the life of a drive motor by reducing a load which is applied to the drive motor when a drive shaft comes to a sudden stop due to a power shutoff. To this end, the motor device comprises: a drive motor having a drive shaft which operates in forward and backward directions by a control of a control unit when power is applied; a clutch unit which is connected to the drive shaft of the drive motor in rotatable manner via a drive shaft coupling key, transfers power in response to a control of the control unit which applies and shuts off power, and stops transferring power when the power is shut off and the drive shaft idles; a brake unit which has one end connected to one end of the clutch unit via a clutch coupling key for brake connection and is provided to stop or transfer driving power in response to a control of the control unit which applies and shuts off power; and a decelerator which has one end connected to the other end of the brake unit and is intended to slow down and output the driving power. |
