Title:
INDUCTION MACHINE
Document Type and Number:
Japanese Patent JP2017225274
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an induction machine in which a cogging torque is small.SOLUTION: A disk type power generator 1 comprises: a back yoke 12 made from a magnetic material holding a magnet 121; and a coil yoke 11 made from the magnetic material to which a coil 111 wounding an electric wire is provided. In the disk type power generator, the back yoke 12 and the coil yoke 11 can be relatively rotated while maintaining a state where the coil yoke 11 is faced to pole faces 121 N/S of the magnet 121 held by the back yoke 12. The coil yoke 11 has an annular shape so that a faced surface 118 faced to the pole surfaces 121 N/S is extended to a peripheral direction.SELECTED DRAWING: Figure 1
