Abstract
A high-precision magnet encoder in which high-order harmonic components can be suppressed without increasing the number of lead wires connecting magnetic field detecting elements to a signal processing circuit. Hall sensors of phase A, phase B, phase Aand phase Bare arranged sequentially around a permanent magnetat intervals of 90 degrees via an air gap. Hall sensors of phase C, phase D, phase C, phase Dare arranged at positions 60 degrees away from the Hall sensors of phase A, phase B, phase Aand phase B, respectively. Connection is made between the positive output terminals of a set of Hall sensors located at positions 60 degrees away from each other and between their negative output terminals.
