  • Three phase spin motor power meter
    Patent number: 4028623
    Abstract: The power meter provides an analog output voltage which is proportional to ower for both sine wave excitation and all other excitation types. The circuit of the meter involves the use of electronic multipliers to produce the low-ampere product of voltage and current in real time, and sums the results to produce the total power output representation for all phases.
