| Abstract: | One of the digital tachometer of the electromagnetic induction is introduced. The induced electromotive force at the secondary coil can be got by changing the flux of the primary coil. And the force of magnetic is amplified in proportion to the amplification of the magnetic resistance. The digital output can be directly obtained by using this method. Thus the range of putting out signals is big enough and produces a strict linear relationship with rotating speed. |
