On the Invention of “Revolving Type Electric Meter”

Abstract

It is well known that working energy of the electric meters has been limited to only two of the electric and the magnetic energy, and the difficulty of the construction of high sensibility meters and the expensiveness of these price are mainly owing to the limitation of the working energy. The author recently invented a new electric meter, the “Revolving type electric meter”, and obtained a patent (registered No. 38921), The following article gives the statement of its theory and construction principle;- In this meter the mechanical energy is easily used as the working energy in addition to the electric and the magnetic energy, by the constant speed separately excited generator principle, and its theory and principle can be effectively applied for the wide range of electric meters and measuring instruments.
