PURPOSE:To equalize the output of a position detector and the counter electromotive output patterns of phases and to reduce a torque ripple and wow and flutter by suitably determining the pattern of a coil for a flat brushless motor. CONSTITUTION:Unit coil poles 1a-1i formed of 9 spiral pattern conductors and through holes 4a-4c for disposing position detectors are formed on one coil sheet 1. 4 spiral unit coil poles of the poles 1a-1d are deformed, the positional relationship of deforming phase coils as a whole and the total sum of deforming amounts are electromagnetically equalized equivalently so that the sum of the patterns of the counter-electromotive output of the same phase coils become the same among the phases. The position detectors are buried in the holes 4a-4c so that the outputs become the same. |
