PURPOSE:To enable the torque constant of a motor to be easily varied, by connecting the two points of a coil conductor to each other between them via a superconducting member. CONSTITUTION:A stator coil 1 is composed of a 6-turn winding, and a part of a first - a third turn coil is connected via a superconducting member 2. When the superconducting member 2 is in a superconducting state, then a conductor A and a conductor B are short-circuited via conductors C, and the stator coil 1 is equal to the coil of a three-turn winding. When the superconducting member 2 is not in a superconducting state, then the conductor A and the conductor D are in an insulated state, and the stator coil 1 shows the characteristic of the 6-turn winding coil. Accordingly, if characteristic showing the superconduction of the superconducting member 2 is controlled, the torque constant of a motor can be controlled. |
