<p>PROBLEM TO BE SOLVED: To improve the assemblability of air core coils.SOLUTION: A generator includes: a shaft member; a plurality of first permanent magnets annularly arranged circumferentially with respect to the shaft member; a plurality of second permanent magnets annularly arranged in opposition to the respective first permanent magnets; a plurality of air core coils annularly arranged circumferentially with respect to the shaft member in a space between the first permanent magnets and the second permanent magnets; a disklike coil support fixed to the shaft member coaxially with the shaft member and supporting the plurality of air core coils; and a magnet support rotatably mounted on the shaft member, housing the coil support and supporting the first and second permanent magnets. The coil support has, for each air core coil, a bottomed recessed portion which the air core coil is mounted on.</p> |
