arduino - PWM an AC pump using MOSFET



I'm currently stuck on my project as I'm not sure what to do with PWMing my pump as I want to adjust the pressure.


I will be using an Arduino for PWM. The pump is 60W @ 230V 50Hz mains and is a vibratory pump, it has a built in diode so it only sees half of AC signal.


My question is would this circuit work? Do I need to add additional passive components? I think I do, but I don't know what or where should I add them.


current circuit


Thanks in advance!

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
