Motor electronic governor controller 6
The circuit work theory This motor electronic governor controller circuit is composed of power supply circuit, ultralow-frequency oscillator and control implement circuit, the circuit is shown in the figure 8-63. The power supply circuit is made of depressurization capacitor C3, bleeder resistor R1, rectifier diodes VD3, filter capacitors C1 and steady voltage diode VS. The ultralow-frequency oscillator consists of time base integrated circuit IC, resistors R2-R4, potentiometers RP, capacitor C2 and diodes VD1, VD2. The control implement circuit is composed of solid state relay KN(SSR)、transistor VT and resistor R6.
