More Information
Summary:The electric rotating machine includes a rotatable rotor including first magnetic field parts and second magnetic field parts formed in front and rear surfaces, respectively, by arranging permanent magnets in a circumferential direction; a first stator equipped with coils opposing the first magnetic field parts disposed, the coils forming first stator magnetic fields; a second stator equipped with coils opposing the second magnetic field parts disposed, the coils forming second stator magnetic fields; and a power feeder for driving the rotor to rotate by supplying power to the coils, and a power collector for extracting an induced current generated in the coils of the other stator resulting from rotation of the rotor. At least the coils disposed on the power supply side are formed by a superconducting material, a current supplied to the superconducting coils being made larger than an induced current generated in the other coils.
