Title:
LONG TRANSFORMER FOR NONCONTACT POWER SOURCE
Document Type and Number:
Japanese Patent JPH05308025
Kind Code:
A
Abstract:
PURPOSE: To provide a long transformer for non contact power sources which can supply a power supply voltage to a moving load in a non-contacting state.
CONSTITUTION: After a primary coil 4 is wound around the long section 2 of a magnetic core 1, a secondary coil 6 is movably wound around the section 2 so that the winding of the coil 6 can partially overlap the winding of the coil 4. Therefore, a power supply voltage can be supplied to a load 9 from the coil 6 in a non-contacting state even when the load 9 is always moved in Xand Y-directions by means of a mobile body 8 fitted with the load 9.
