This interior magnet rotary electric machine () is provided with a rotor () that has a rotor core () having two sets of permanent magnets () embedded therein, and with a stator () that is disposed facing the rotor (). The two sets of permanent magnets () each comprise a pair of magnets () of like polarity disposed adjacently along the circumferential direction of the rotor. In the rotor core (), magnet embedding holes (), which accommodate the magnets () of like polarity, are formed for each of the magnets of like polarity. The thickness (a), in the rotor () circumferential direction, of the portions () of the rotor core () between like poles is less than the thickness (b) of the portions () of the rotor core () between unlike poles.

Interior magnet rotary electric machine

This interior magnet rotary electric machine () is provided with: a rotor () that has a rotor core () having permanent magnets () embedded therein; a stator () that is disposed facing the rotor (); and a fiber-reinforced plastic tube () that is fitted over and fixed to the rotor core ().

An axial gap type dynamo-electric machine () comprises: a stator () provided with a magnetic core () and an exciting coil (); a rotor () provided with a plurality of permanent magnets () circumferentially arranged around a rotation center axis (AX), the rotor () being also provided with a disk-shaped base material () for supporting the permanent magnets, the rotor () being disposed at an axial distance from the stator (); and affixation members () for affixing the permanent magnets () to the base material (). The permanent magnets () are provided with front surfaces facing the stator (), rear surfaces facing the base material, and engagement-receiving sections () formed at peripheral edges of the permanent magnets (). The affixation members () include: engagement sections () engaging the engagement-receiving sections; and affixation sections () forming mechanical affixation structures relative to the base material.

Axial-gap rotating electric machine

The invention is characterized in: forming a magnetic field inside a flow channel tube, the tube wall of which is formed from a material that is nonmagnetic and which, when the pressure outside the flow channel tube is lower than the pressure inside the flow channel tube, passes a portion of the air flowing inside the tube through the tube wall and discharges same to the outside thereof; supplying air to the flow channel tube so that at least a region of laminar flow is formed inside the flow channel tube; and reducing the pressure outside the flow channel tube to a prescribed pressure.
