Patent ID: 6915558

Claim:
A method of assembling a separable transformer onto an object, wherein said separable transformer comprises a primary core and a secondary core adapted to be opposed to each other and to effect contactless transmission of at least one of a signal arid energy therebetween, said method comprising: mounting said primary core directly on a primary unit of the object adapted to be provided with the primary core and carrying out electric wiring, to thereby assemble a primary sub-module; mounting said secondary core directly to a secondary unit of the object adapted to be provided with the secondary core and carrying out electric wiring, to thereby assemble a secondary sub-module; and assembling said primary sub-module including the primary core and said secondary sub-module including the secondary core together, with said primary and secondary cores opposed to each other; wherein: said primary core comprises a stator core mounted to a stationary member, and said secondary core comprises a rotor core mounted to a rotation shaft rotatably supported by said stationary member, said rotation shaft is provided with a guide member including a first reference face defining a reference position in a diametrical direction of the rotation shaft and a second reference face defining a reference position in an axial direction of the rotational shaft, and said stator core and said rotor core are respectively mounted to said stationary member and said rotation shaft with reference to said first and second reference faces of said guide member.
