<p><P>PROBLEM TO BE SOLVED: To realize a motor capable of demonstrating suitable drive state and regeneration state in accordance with running conditions in a simple configuration. <P>SOLUTION: A wheel construction 1 is constituted by providing a stator 13 changing a magnetic pole within a caliper generating braking force by pressing a brake pad to friction sliding surfaces 2a, 2b of a disk rotor 2, setting a permanent magnet 3 on the friction sliding surfaces 2a, 2b of the disk rotor 2, and allowing the stator 13 to be set in the drive state that generates driving force rotatably driving the disk rotor 2 and in the regeneration state that generates electromotive force by rotation of the disk rotor 2. The stator 13 can be brought into close contact with the permanent magnet 3 of the disk rotor 2 and be separated apart from the permanent magnet 3 by hydraulic pressure for a brake. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
