When you talk about 3 phase motors I am thinking that you could measure ac voltage between any 2 of the phase wires and frequency would give an indication of the speed. My reference is from variable speed inverter drive motors that are used in residential air conditioners and industrial motors. Of course you would check the inputs to the module first. I saw phase 2 and 3 labeled on diagram. Is phase 1 connected to ground? Thanks for the Videos

You could do that also. I'm gonna wait for another opportunity to make another video on one that operates and use advanced tools to check it. Preferably in my shop. This video is intended to the DIYer. The third phase is not grounded. That is a grounded shield.
