The present invention relates to a motor for motor driven power steering (MDPS). According to the present invention, a motor is connected to a worm shaft engaged with a worm wheel and rotated in an MDPS housing, protrudes toward the worm shaft to transfer power when a power supply unit is turned on, and is separated from the worm shaft to cut off the power when the power supply unit is turned off. The motor comprises a driving blocking unit transferring rotary power when the power occurs and blocking the power when failure occurs. According to one embodiment of the present invention, the motor transfers the power to the worm shaft through the driving blocking unit installed in the motor, is separated from the worm shaft to block the power when the failure occurs in the motor, and it is also prevented that steering power is rapidly increased in a steering wheel.

    본 발명은 전동조향장치용 모터에 관한 것으로서, 전동조향장치(MDPS) 하우징 내에서 웜 휠과 치합되고 회전작동하는 웜 샤프트와 연결되어, 전원 온(ON)시 상시 웜 샤프트에 돌출되어 동력을 전달하고, 전원 오프(OFF)시 상기 웜 샤프트로부터 분리되어 동력을 차단하는 모터에 있어서, 상기 모터는 동력 발생시 회전력을 전달하고, 고장 발생시 동력을 차단하는 구동 차단부를 더 포함하여 이루어질 수 있다. 본 발명의 실시 예에 따르면, 모터에 장착되는 구동 차단부를 통해 모터의 동력을 웜 샤프트에 전달하고, 상기 모터의 고장 발생시에는 웜 샤프트와 분리되어 동력을 차단할 수 있을 뿐만 아니라 핸들 조향력이 급증하는 것을 방지할 수 있는 효과가 있다.
