Abstract
An electromagnetic device includes a plurality of coils formed by winding conductors. At least some of the conductors are constructed by stacking conductor constructional elements so that an eddy current generated by a leakage flux linked to the conductor is divided. An outer insulating member is disposed on an outer circumferential surface of the conductor stack for electrically insulating the conductor stack from another member. An inner insulating member whose thickness is smaller than a thickness of the outer insulating member is disposed between the conductor constructional elements adjoining to each other in the same conductor stack.
