Abstract
An energy converter includes a magnetism generation mechanism unit that generates a magnetic field when connected to an AC electrical power source, and a rotating mechanism unit having a single turn coil array member in which a plurality of single turn coils is disposed at a predetermined interval and a soft magnetic metal plate disposed on a side of the single turn coil array member opposite to the magnetism generation mechanism unit. The rotating mechanism unit is structured such that the single turn coil array member faces the magnetism generation mechanism unit across a predetermined magnetic gap and rotary driven by the magnetic field. Here, a drive signal period of the electrical power source is a period that maximizes an eddy current generated in the soft magnetic metal plate.
Claims8
An energy converter, comprising
- a magnetism generation mechanism unit that generates a magnetic field when connected to an AC electrical power source;
- and
- a rotating mechanism unit having a single turn coil array member in which a plurality of single turn coils is disposed at a predetermined interval and a soft magnetic metal plate disposed on a side of the single turn coil array member opposite to the magnetism generation mechanism unit, the rotating mechanism unit being structured such that the single turn coil array member faces the magnetism generation mechanism unit across a predetermined magnetic gap and rotary driven by the magnetic field,
- wherein a drive signal period of the electrical power source is a period that maximizes an eddy current generated in the soft magnetic metal plate,
- wherein the drive signal period Tg of the electrical power source satisfies a condition represented by Formula (1) given below.
- Tg=4td (1)
- (where, td is a response time for eddy current due to a magnetic flux penetrant diffusion wave into the soft magnetic metal plate to become maximum with respect to predetermined stepwise voltage application by the electrical power source and td is determined experimentally).
