Embodiment
As can be seen from Fig. 1, electric main produces DC power supply through transformer step-down, rectification, filtering, voltage stabilizing etc., supplies with work such as oscillator, speed regulator, controller, reaches motor is rotated on request, drives the purpose of rapping arm work.
Fig. 2 illustrates, and this novel rapping arm that is installed on the direct current arbor that comprises also has 180 ° of steering controling circuits of direct current machine: by AC transformer, rectification circuit, filter circuit, voltage stabilizing circuit and 0.5HZ low-frequency oscillator in turn cascade form; 0.5HZ low-frequency oscillatory network is: positive source is connected to triode BG1 collector electrode after being connected in series relay J 1 and resistance R 2 in turn, electrochemical capacitor C2 positive pole is connected to triode BG1 collector electrode, electrochemical capacitor C2 negative pole is connected to triode BG2 base stage, electrochemical capacitor C3 positive pole is connected to triode BG2 collector electrode, electrochemical capacitor C3 negative pole is connected to triode BG1 base stage, two front ends of duplex potentiometer W1 all connect positive source, be connected to electrochemical capacitor C2 negative pole behind the rear end series resistor R3 of duplex potentiometer W1, be connected to electrochemical capacitor C3 negative pole, triode BG1 behind the series resistor R4 of another rear end of duplex potentiometer, the emitter of BG2 all connects power cathode; Power rectifier bridge D1-4 output cathode serial connection relay J 1 often open coil one end that is connected to direct current machine D behind the node J1-1, positive source serial connection relay J 2 often open the coil other end that is connected to direct current machine D behind the node J2-1, be connected to coil one end of direct current machine D behind the normally closed node J1-2 of power cathode serial connection relay J 1, be connected to the coil other end (the controlled polarity of motor, without circuit such as pressurizer, duplex potentiometer adjusted in concert shuttle speed) of direct current machine D behind the normally closed node J2-2 of power cathode serial connection relay J 2.

Operation principle and circuit structure described in Fig. 1 and Fig. 2 all can be used at aspects such as electric power deicing, flour processing, just use object according to difference, may also need to change frequency parameter and power of motor, and these are not difficult to apply.
Such as in Fig. 2, the speed time is if adjust in 30% scope, just then utilize duplex potentiometer to finish, if but go beyond the scope, just need increase or reduce R
3, R
4, C
2, C
3Realize that it is to slow down that general parameters increases, it is to quicken that parameter reduces.Must note, when frequency of oscillation faster than 10Hz, substantially be in continuous state when being 0.1 second blanking time, and because of the motor magnetic hysteresis loop is difficult to catch up with, be good at realizing 180 ° round reverse, hits meaning so lose beat; And be slower than 0.1Hz in frequency of oscillation, when promptly the time interval is 10 seconds,, lacked work sensation continuously near standstill state.So parameter is selected to want suitably.
Moreover, when:
R
3＝R
4 C
2＝C
3
Be parameter when identical, motor is to make at the uniform velocity back and forth movement.But when according to some place special instructions for use being arranged, as advertising, what have needs retention time long, and what have only need flash again fast, like this, just want conscious being designed to:
R
3≠R
4 C
2≠C

Concrete if want the front time long, the back time is short, then need: R
3＞R
4C
2＞C

If want the back time long, the front time is short conversely, then needs: R
3＜R
4C
2＜C

In addition, if with duplex potentiometer unsolder one side, keep a side, doing to regulate also is a kind of householder method.
So, how is resistance capacitance determined on earth? two kinds of methods are arranged:
The one, according to specific requirement, calculate by following formula:
f＝1/2πRC
In preceding physics and chemistry water treatment facilities, we will get frequency f is 0.5Hz, and selecting electric capacity in this examination earlier is 10uf, that is:
C=10 * 10
-6, in the substitution formula:
0.5＝1/2×3.14×10×10
-6*R
Then: R=0.5 ÷ (0.5 * 3.14 * 10 * 10
-6)
＝0.318×10
5
＝31.8(kΩ)
Be that resistance R can be elected 32k Ω as, but regulate leeway for staying, our adapted the duplex potentiometer of 10k Ω, so the real resistance R of selecting
3=R
4=30k Ω, visible theory and practice has reached unanimity substantially.
The 2nd, debug screening at work again, to arrive ideal effect.
Above-mentioned both combinations will be better more fully selection of parameter methods.
