My project:: I am making a bed with 8 AC motors in the base...each motor will give a different angle of rotation...i will also wire in 16 limit switches one on each end of each motor's motion, so that it doesn't keep moving. I am going to use an arduino mega and 16 buttons... which will move that respective motor either clock wise or anti clock wise and will move it as long as the button is pressed then stopped.
Question:: So i want to be able to reverse each AC motor and also be able to stop it. the programming side is done. the hardware side is also done. i can't seem to find a way to reverse AC motor. i just need a switch type thing which has 3 states in it, CW, CCW, and stop. or in other words, on1, off, on2 and ofc that switch has to be programmable by arduino.
My Attempts:: I have thought about using a DPDT relay which will take care of the reversal. but it will keep reversing... i have thought about using a tripple pole tripple throw relay but that is too rare to find... actually i found some images but i couldn't find a seller.
I have thought about VFD but they are expensive considering i would need one for each motor. and since i dont want to control speed or need 3 phase output it will be overkill. i just need the h-bridge inside that circuit. it would be wonderful i could get a schematic so i can make it myself since im designing the pcb for it myself.
NOTE: I understand that i have not provided enough information about motors and that is important so the motors are single phase AC motor 220V probably universal motor...i haven't decided on the motors..but thats the one im gonna probably use. I just want someone to point me in the right direction since AC world is just so new to me.
