<p>PROBLEM TO BE SOLVED: To improve the assemblability of permanent magnets.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 magnet support has wall portions intervening between adjacent first permanent magnets and between adjacent second permanent magnets, respectively.</p> |
