The AC Motor Proto-Controller, as a circuit, aims to teach the basic concepts of electric motor control. In this case, DC will be used to drive the AC motor, as sort of a way to "train" the designer and user into understanding how concepts such as Pulse Width Modulation (PWM) and MOSFET logic.
The project will consist of the following fairly basic, but useful components:
1.) Six (6) N-Channel MOSFETs (In this case, the IRF1010E);
2.) Six (6) 10 kilo-ohm resistors
3.) One (1) Arduino Nano
4.) One (1) Three-Phase Electric Motor
Note: The Three-Phase Electric Motor may either be AC or DC, as long as it allows for voltages no less than 20 volts
The Concept, Summarized
Using Pulse Width Modulation (PWM), we would be able to control the speed and direction of the Three-Phase Motor by sending pulses of 20 volts DC to the positive terminal of the circuit and by automating the transmission of electrical signals that will come from the Arduino Nano to the gate of each MOSFET simultaneously, energizing the motor's coils. The direction of the motor's rotation will depend on how the user (a.k.a. you, the maker) programs the Arduino Nano.
