I'm building a device that requires control over 3 phase induction AC motor 1.5 kw and 1400 rpm to do the following
1-reverse Motor direction
2-switch motor on/off (frequency up to 1 time per second)
3- Can be controlled by a micro controller (i.e accepts digital signal)
No need for controlling motor speed
what is the device that provides the above mentioned control that is cheaper than a VFD ?
possible solutions that I'm checking now are (VFD , Triac with an opto-coupler , Solid state Relay )
P.S: I have read over 9 posts on AC motor control here but couldn't find what I was looking for.also I'm still learning AC motors and I have little knowledge about them.
