the propulsion components of maglev

You only need to research and have a good understanding about these things. - I need someone to do the research of the logic of on/off switching components so I can buy the right one. - a OPU Optical or PLC, or Read Switch, or Hall Effect Sensor, or a micro control switch, - this logic components will turn the electromagnet on/off 30 - 40 times per second as the logic on the maglev train does. this is what i need your help with - logic components for on and off switching using logic sensors components. that's all. you see i already know the sensors. i need you to help me research which logic components I need . – that is which components that make’s maglev compulsion system to rapidly turn off/on so fast – that is the logic components I need that is the logic i need. ok i know - the manufacturers and where to buy these components. I have their phone numbers you can call and talk with their engineers. I need your help with finalizing which logic component will do what I need.
