By accompanying drawing as seen, the utility model mainly comprises stator, end cap, bearing, rotor shaft, permanent magnet poles, position-limited lever, eccentric wheel, angular position sensor, output fork, angle indicator and angle dial.As shown in Figure 3, stator is made up of stator iron core 4 and stator coil 6, and two alignment circles 6 are wrapped in respectively on the last lower magnetic pole of stator iron core 4 up and down.Left end cap 2 and right end cap 5 fixed covers are in the and arranged on left and right sides of stator iron core 4.Respectively adorn a bearing 3 in the center hole of two end cap.The left and right shaft shoulder of rotor shaft 8 is installed in the interior ring of bearing 3.Rotor shaft 8 stage casing outer surfaces are loaded onto henry chloranthus herb sheet permanent magnet, constitute four permanent magnet poles 7.Shown in Fig. 3 and 5, the two ends of position-limited lever 11 are installed in close right bearing 3 inboards on the right end cap 5, and position-limited lever 11 is horizontally through among the square hole E of rotor shaft 8.As shown in Figure 3, eccentric wheel 9 is fixedly mounted on the right-hand member of rotor shaft 8.Angular position sensor is fixedly mounted on right end cap 5 outer basifacials, be in eccentric wheel 9 under.As shown in Figure 1, 2, output fork 1 usefulness screw 12 is fixedly mounted on the left end of rotor shaft 8.Angle indicator 13 is fixedly mounted on rotor shaft 8 left ends and is in output fork 1 right-hand near left end cap 2.Angle dial 14 is fixedly mounted on left end cap 2 outsides and is in the indicated scope of angle indicator 13.
The working principle of this speed governing actuating device is: when no current passes through in the stator coil 6, the magnetic pole of stator iron core 4 does not produce magnetic field, with the interaction force of the permanent magnet poles 7 of rotor to make a concerted effort be zero, rotor can freely be parked in any position in 75 ° of (0～100%) scopes.When in the stator coil 6 when the forward current, the making a concerted effort of the interaction force of stator field and rotor field rotor shaft 8 is driven to export forks 1 to turn to the big aperture of fuel valve position, motor is speedup then.Otherwise, when in the stator coil 6 when the back current, the making a concerted effort of the interaction force of stator field and rotor field rotor shaft 8 is driven to export forks 1 to turn to the little aperture of fuel valve position, motor then slows down.When practical application, whether want galvanization in the stator coil 6, still determine by the state that is conditioned object by back current by forward current.When for example this actuating device is used for rotational speed regulation that combustion gas starts, if the current actual speed of motor is lower than the rotating speed of setting, then speed controller can be exported the voltage of a rising, the result that this voltage is compared with the output voltage of the angular position sensor of actuating device be one on the occasion of, controller will feed the electric current of forward in the stator coil 6 of actuating device, actuating device will be to the direction deflection of aperture increase, the fuel valve of motor is opened greatly, and the actual speed of motor will rise.If instead the current actual speed of motor is higher than the rotating speed of setting, then speed controller can be exported the voltage of a decline, the result that this voltage is compared with the output voltage of the angular position sensor of actuating device is a negative value, controller will feed reverse electric current in the stator coil 6 of actuating device, the direction deflection that actuating device will reduce to aperture, the fuel valve of motor is turned down, and the actual speed of motor will descend.When the current actual speed of motor equates with the rotating speed of setting, the output voltage of speed controller is constant, this voltage equates that with the output voltage of the angular position sensor of actuating device it is zero that controller makes the electric current that feeds stator coil 6, and the output angle of this actuating device is constant.
This actuating device has self-locating function, can not change the angle outgoing position because of other external factor when being conditioned system stability work.Its principle is: when being conditioned parameter and equating with setting value, the regulating voltage of controller is a certain value, if a certain external factor makes this actuating device produce deflection to the direction that aperture increases, then the output voltage of the position transducer of actuating device just rises, the result of the output voltage comparison of the regulating voltage of controller and position transducer is a negative value, controller promptly feeds back current in the stator coil 6 of actuating device, the result makes actuating device to the direction deflection that aperture reduces, and makes the reposition of aperture position.Same make actuating device when aperture reduces direction deflection when external factor, can make its reposition by the generation forward current in the stator coil 6.
Because controlled device is to work in steady state in most times, this actuating device is to maintain a certain definite position in most of times, the electric current most of the time of passing through in the stator coil 6 of actuating device is zero, actuating device is not power consumption under this state, so power consumption is very low, itself generates heat very light.
This actuating device is that contactless nothing is worn and torn between the eccentric wheel 9 of the inductive head 10 of its angular position sensor and rotation in course of action all the time, and it is very reliable to work.
The hot-wire coil 6 of this actuating device is fixed, and the electric current that leads to coil 6 like this needn't adopt carbon brush, can guarantee long working life.Because it is single-phase leading to the electric current of coil 6, so lower to the requirement of control circuit.
The rotor shaft 8 of this actuating device can directly be exported bigger moment of torsion (greater than 10Nm), acceleration and deceleration mechanism in addition, and simple in structure so speed of response is fast, cost is lower.
