Rotary electrical machine

Abstract

Provided is a rotary electrical machine capable of suppressing an increase in eddy current in the rotary electrical machine and significantly reducing a loss of a coil. The rotary electrical machine includes a stator having a coil and a first magnetic core, and a rotor having a permanent magnet and a second magnetic core. The rotary electrical machine includes a magnetic structure provided in at least one of two coil end portions that are both ends of the coil, the magnetic structure inducing magnetic flux directed from the second magnetic core toward the first magnetic core. Here, the magnetic structure guides the magnetic flux directed from the second magnetic core to the first magnetic core in a radial direction of the rotary electrical machine and guides the magnetic flux in a circumferential direction of the rotary electrical machine. In addition, the magnetic structure is provided such that the magnetic flux does not substantially interlink with the coil.
