Can anyone provide me with the math for a balanced mixer. I looked thru all of my old textbooks, and can only find the math for a simple mixer. I.e., 2 * Cos(A) * Cos(B).
Thanks.
Here's a puzzler for you guys. It has me stumped at the moment.
I have a prototype circuit, real pcb, on which I have a Caddock MP2060 non-inductive resistor of 0.05 ohms. I was trying to use it for current sensing. However, the voltage produced across it doesn't match the current measured...
Is anyone experiencing bearing failure in VFD motors? If so, what have you done to solve the problem? Is it worse with some VFDs than with others? What are your motor sizes? How long are your motor leads? Any other useful thoughts would be appreciated.
