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. |
