I have a 120v AC induction motor with 4 taps: high, medium-high, medium-low and low.
Even the low tap is much too fast for my application, so I'll use a variac to bring the voltage down even further.
The question is: does it matter which tap I use with the variac?
Intuition suggests to use low, but I can't formulate a scientific explanation.
