התרחיש
A vibratory feeder needs an adjustable 0–300 Hz pulse train to modulate coil current and control feed rate.
מה מופיע בתרשים הזה
פענחו את ההחלטות שמאחוריו.
01
Use a 555 timer in astable mode with a 500k potentiometer for continuous 0–300 Hz frequency adjustment
02
Drive the coil with an N-channel MOSFET and add a flyback diode for inductive kickback protection
Reuse for variable low-frequency pulse generation driving inductive loads such as vibratory feeders, solenoid hammers, or buzzer coils.
