I'm designing a hairdryer as project for a university class, but I'm having trouble regarding the choice of the motor. I need it to have two possible speeds. My first idea was to use an AC motor and a diode as in the schematic below, when the current flows through the diode, half of the AC wave gets cut, so the motor runs at half speed. My first question is: Will it work?
I also tried to use a DC motor instead with a rectifier bridge, but using the aforementioned diode to cut the wave in half doesn't seem to change to voltage on the motor very much, how can I make it work with I choose to use a DC motor?
Thanks in advance.
