Noncontacting electric power transfer apparatus, noncontacting signal transfer apparatus, split-type mechanical apparatus employing these transfer apparatus, and a control method for controlling same |
摘要 |
A noncontacting power transfer apparatus, a noncontacting signal transfer apparatus and a separate machine apparatus that uses these couplers are disclosed. The power coupler is composed of a primary side and a secondary side that are fixed to a static unit and rotatable unit of the machine apparatus, respectively, such that its output does not vary with arbitrary rotation by the rotatable unit. The signal coupler is composed of receiving side portion having a electric-to-light conversion device that converts an electric signal to an optical signal of rotational symmetry relative to the axis of rotation of the rotatable unit and a photoelectric conversion device that converts an optical signal to an electric signal. Accordingly, the rotatable unit can be supplied with power from the static unit even while rotating, and moreover, can communicate with the static unit. Further, the rotatable unit can be easily attached to the static unit and can be removed from the static unit.
