The detection sensor 53 senses the rotation position (angle) of the arm 55 and applies it to a control unit to be described later. Accordingly, the engine is operated in various modes by the operation of the driving motor M, for example, the lowest point at which the engine is stopped, the starting point of the idling state, or the maximum point mode at which the engine is operated at the maximum, The operation of each mode is precisely controlled by

In the embodiment of the present invention as described above, since the reducer R is integrally provided with the driving motor M, and the detection sensor 53 is installed inside the cover 50 through the angle frame 53a, the prior art of the switch bracket (1-29) can be omitted, and since the angle frame (53a) is bolted to the long hole of the cover body (51), the installation angle of the detection sensor (53) can be easily adjusted, and the actuator is compactly configured can do.

Meanwhile, the actuator may include a driven shaft 63 , an encoder 65 , a calculation unit 71a , a storage unit 71b , and a reset unit 71c as shown in FIGS. 10 and 13 .

That is, the calculator 71a calculates the rotation speed or angle of the driving motor M corresponding to the lowest point when the engine is stopped, the starting point in the idling state, and the maximum point at which the engine operates at the maximum. The calculation unit 71a calculates the number of rotations or the rotation angle of the driving motor M through the pulse or current value applied from the encoder 65 and stores the calculated value through the storage unit 71b,

The reset unit 71c resets the zero point of the driving motor M based on the number of rotations or the rotation angle of the driving motor M sensed through the encoder 65 . The reset unit 71c resets the zero point of the driving motor M based on the calculated value of the storage unit 71b when the engine is restarted after the engine is stopped. For example, the reset unit 71c checks the rotation angle of the driving motor M through the calculated value stored before restarting, and resets the current state of the driving motor M to the zero point if the rotation angle is not the zero position. . Accordingly, the driving motor M is driven without repeated error. That is, when the driving motor M is repeatedly driven without being reset to the zero point, the driving motor M cannot be operated precisely due to a repetition error. However, since the driving motor M is reset to the zero point by the reset unit 71c as described above, it can be stably operated.

In the setting unit 83a, the period and time for automatically driving the engine are set. For example, the setting unit 83a may be set to 8:00 pm after one month,

The counting unit 83b counts the period and time set in the setting unit 83a, and applies a completion signal when the counting is finished. The signal applying unit 83c operates according to the left side signal of the counting unit, and applies a driving signal or a driving stop signal of a driving motor constituting the actuator so that the driving of the engine is automatically controlled. The driving confirmation unit 83d checks the driving state of the driving motor M to check the driving of the engine through the driving motor M of the actuator driven by the signal applying unit 83c, that is, the driving confirmation unit ( 83d) operates the driving motor M when a driving signal is applied from the signal applying unit 83c to drive the engine, and when a driving stop signal is applied, stops the operation of the driving motor M to drive the engine stop And, the driving check unit (83d), if the driving motor (M) does not operate according to the signal is determined to be a failure and warns of an abnormality through the above-described warning unit (72).
