Hello Marvin,
Welcome to the forum, :Welcome: , I have moved your topic into the student zone as you will get a better response in here.
It is doubtful that anyone here will give you the answers to your questions directly TBH.
Please have a go and let us know what methods you feel suitable and we will then willingly critique those attempted answers.
For example, if you had one on a 3ph squirrel cage induction motor, and how could this be reversed.

We then have the opportunity to explain which bits are wrong and right, or ask you to go into further depth so you can build your underpinning knowledge and grow your competence with the theory side of things.
So, to that end, please come back to us with your ideas on the questions and I'm sure that some of the others around here would be willing to give you some more pointers.
