If a 3 phase motor is over spead , it generates power back into the line.
I saw this years ago and it was for a windmill generator that used a 3 phase motor.
A simplistic and inexpensive set up as no $3000.00 grid tie was needed.
The logic was if the motor can be run (powered) then when driven to a speed above what it runs it genertes power back and all is happy as far as the a/c is concerned (in sync?)
Any body have an idea if this works with rpc or vfd driven motors? If the motor is running and I speed it up with a windmill or gas motor will it generate back and will the rpc or vfd be able to handle this?
