Hi everyone,
Some hydraulic valve system use Solenoid to control the flow of Hydraulic. The electrical signal supplied to Solenoid could be both DC voltage or PWM ( Pulse With Modulation). The question is what happens if we change the frequency of PWM , for example if we change the frequency of PWM from 100 HZ to 330 HZ , how that affects the operation of Solenoid ?
I made a experiment to supply same DC current (1 A) to both 10 ohm Solenoid and 10 ohm resistor. Could anyone know why the heat generated from 10 ohm Solenoid is not so much compared with the heat from 10 ohm resistor Thank you so much
