I am looking for a simple circuit for controlling 3 phase motor. I Have an application. I would like to create a small demo project before going into bigger implementation
I have a borewell. 3 phase motors are used to pump water from the borewell. I am going to connect a water flow sensor to check volume or whether water is flowing or not. if there is no water flowing in the sensor motor will be running idle state. I wanted to cut off the motor supply when the water flow is zero. else it should keep running.
Can someone suggest to me the necessary component and schematic to execute the project?
I am planning to use node MCU/ Water flow sensor/ DC motor/Relay board to make the demo version.
My question how can replicate this application.
Let me know if any better application and sensor can be used.
