Yes, what you say sounds like the situation that is happening. I am worried about changing the sizes of the pulleys to change the ratio of the wheel head, because that would still result in a wheelhead that spins at a fixed speed - albeit a bit slower. Furthermore, I am not sure I could fit a larger ratio into the wheel I have (See photos attached on my other comment). The current method of controlling the speed is by loosening or tightening the belts - so at the "slowest" setting the belt slips more. But I find this method ineffective. I will look into the frequency inverter, since I think that could give me a bit more control. Thank you for the suggestions!

Hi, Thank you for your response. The wheel is driven by two belts. I attach some photos. Thanks again!

I recently acquired an old electric pottery wheel that runs on an AC motor. The wheel has no way of regulating the speed of rotations, so it just goes at one set speed that is too fast to do anything with. I tried using a variable voltage controller to reduce the current that reached the motor, with the hopes that that would slow the rotations of the wheel. At lower voltages the wheel would just stop, and once the voltage was just high enough (180V I think) the wheel would spin at full speed again. Any ideas on how to reduce the revolutions of my wheel? Thank you!
