Source: InternetPublisher:狂妄火龙果 Keywords: phase locked loop integrated circuit generator Updated: 2020/01/05
Example of application of MC14046 in steady speed control of recording paper drive motor
. The reference pulse 256Hz is input from pin 14, and the feedback pulse is generated by the tachometer generator
FG
coaxial with the motor M as a sine wave signal. After amplification and shaping, it becomes a square wave
pulse signal and is input from pin 3. The phase comparator output PC2 (pin 13) is
filtered by a T-shaped resistor-capacitor network and controls the amplifier composed of composite tubes to drive the DC motor.
