Title:
ELECTRIC COMPRESSOR
Document Type and Number:
Japanese Patent JP2023122318
Kind Code:
A
Abstract:
To obtain a more satisfactory damping effect.SOLUTION: A first coil 34A and a second coil 34B are disposed in parallel with each other so as to generate an annular magnetic flux φ100 passing both the inside of a first linear part 51A and the inside of a third linear part 51B by a current i1 flowing to a first winding wire 60A and a third winding wire 60B. The annular magnetic flux φ100 passing both the inside of the first linear part 51A and the inside of the third linear part 51B is generated by the current i1 flowing to the first winding wire 60A and the third winding wire 60B, such that leakage magnetic fluxes generated from the first coil 34A and the second coil 34B are strengthened each other. Thus, mutual inductance is generated. Damping effects generated in a first conductor 70A and a second conductor 70B then become greater in proportion to the mutual inductance.SELECTED DRAWING: Figure 5
