Effciency gains can be 4-6% on a PWM drive --
1.33*Motor HP x hrs operating x Cost/KWH x Effciency Gain = savings in electricity costs
Thus for a 100hp motor at $0.10 / KWH at 5% gain
it will save about $5890/yr savings in electricy costs
Blog Doing Math in FPGAs Tom Burke 18 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
