摘要： PROBLEM TO BE SOLVED: To provide a method of winding a coil for a detector, which suppresses a reduction in accuracy of detecting an angle by reducing interference of magnetic flux leaking from a rotating transformer to a stator without adding new components nor new work processes. SOLUTION: In a method of winding a coil for a detector, a winding group for one phase is constructed so that a magnetic flux distribution obtained by connecting a winding group wound around fixed magnetic poles in series may follow a sine wave distribution of 2P poles, and a winding group for n phases is constructed by using a plurality of winding groups for one phase so as to obtain a sine wave magnetic flux distribution of 2P poles and n phases. Crossover wires between the fixed magnetic poles in the winding groups for one phase are so formed that a half of the crossover wires (for example, crossover wires of winding group 1) and the remaining half of the crossover wires (for examples, crossover wires of the winding group 4) are in opposite directions along the circumferential direction of a stator core and that the total length may be the same.
