The present invention relates to a safety apparatus for a linear motor actuator and, more specifically to a safety apparatus for a linear motor actuator which additionally winds a plurality of coils, thereby nothing interrupting an operation of the linear motor actuator, even if a problem occurs in one coil. The safety apparatus comprises: a magnetic unit in which magnetic materials of N-polarity and S-polarity are alternately arranged in the lengthwise direction; a core unit provided in parallel by being spaced at certain intervals from the magnetic unit, in which a coil unit having a plurality of coils wound therein are arranged in the lengthwise direction; a control unit for controlling power supply of the coil unit; and a power supply unit for supplying power to the control unit. 본 발명은 선형모터 액추에이터 안전장치에 관한 것으로서, 보다 상세하게는 별도의 코일을 복수로 감음으로써, 하나의 코일에 문제가 발생되어도, 선형모터 액추에이터의 동작에 지장이 없는 선형모터 액추에이터 안전장치를 제공한다.
