I am designing a turntable which will be used to spin plants to demonstrate to first year university students that they will grow towards the axis of revolution.
To do this I need a motor. I have decided to go with a three-phase AC induction motor, and with it I am going to get a VFD (variable frequency drive). I will be using a fan-belt drive.
My question is: am I going to have to adjust the diameter of the shaft of the turntable in my design in order to cater for the difference in speed (rpm) of the motor and the speed I want the turntable to rotate at (49 rpm), despite the VFD or will having the VFD mean I don't have to worry about that too much? That is one thing I am stuck on at the moment.
Any help on this matter would be much appreciated. Thank you.
